Firing Notes
1. The Lower Heating Value (LHV) of the fuel efficiencies shall be used for efficiency calculations
2. Typical radiation heat loss value of 1.5% is used typically considered. However, in cases with a flue gas/air preheater, a value of 2.5% is normally considered.
3. Typical Excess Air values can be used as follows:
- Natural Draft - 15% excess air
- Forced Draft - 10% excess air
4. API 560 - Pressure at the Arch should be maintained at -2.5mmH2Og (-0.1inH2Og)
Tube Support Notes
1. Design temp. for tube supports should be Arch temp + 100 C (180 F)
2. No credit should be considered for shielding effect of tube supports by refractory
3. API 560 states if fuel the Vanadium + Sodium content in fuel exceeds 100ppm, supports to be either:
- 50Cr-50Ni metallurgy, without any coating
- Covered with 50 mm (2 in) of castable refractory (see API 560)

Notes
1. Environmentally friendly body-soluble fibre is the recommended choice for fire insulation
2. HW and MW Castable is strong enough to be used on floor without a top brick layer
3. Ceramic fibre insulation are typically used in all areas except stack and ducting.
4. Ceramic fibre not suitable for convection sections with sootblowers or steam lances are used for cleaning.
5. Vapour barrier protective coating is required behind all areas lined with ceramic fibre
6. SS foil barrier is required for ceramic fibre lined areas if the sulphur content exceeds 500ppm by mass.

Firing Notes
1. The Lower Heating Value (LHV) of the fuel efficiencies shall be used for efficiency calculations
2. Typical radiation heat loss value of 1.5% is used typically considered. However, in cases with a flue gas/air preheater, a value of 2.5% is normally considered.
3. Typical Excess Air values can be used as follows:
- Natural Draft - 15% excess air
- Forced Draft - 10% excess air
4. API 560 - Pressure at the Arch should be maintained at -2.5mmH2Og (-0.1inH2Og)
Tube Support Notes
1. Design temp. for tube supports should be Arch temp + 100 C (180 F)
2. No credit should be considered for shielding effect of tube supports by refractory
3. API 560 states if fuel the Vanadium + Sodium content in fuel exceeds 100ppm, supports to be either:
- 50Cr-50Ni metallurgy, without any coating
- Covered with 50 mm (2 in) of castable refractory (see API 560)

Notes
1. Environmentally friendly body-soluble fibre is the recommended choice for fire insulation
2. HW and MW Castable is strong enough to be used on floor without a top brick layer
3. Ceramic fibre insulation are typically used in all areas except stack and ducting.
4. Ceramic fibre not suitable for convection sections with sootblowers or steam lances are used for cleaning.
5. Vapour barrier protective coating is required behind all areas lined with ceramic fibre
6. SS foil barrier is required for ceramic fibre lined areas if the sulphur content exceeds 500ppm by mass.

Firing Notes
1. The Lower Heating Value (LHV) of the fuel efficiencies shall be used for efficiency calculations
2. Typical radiation heat loss value of 1.5% is used typically considered. However, in cases with a flue gas/air preheater, a value of 2.5% is normally considered.
3. Typical Excess Air values can be used as follows:
- Natural Draft - 15% excess air
- Forced Draft - 10% excess air
4. API 560 - Pressure at the Arch should be maintained at -2.5mmH2Og (-0.1inH2Og)
Tube Support Notes
1. Design temp. for tube supports should be Arch temp + 100 C (180 F)
2. No credit should be considered for shielding effect of tube supports by refractory
3. API 560 states if fuel the Vanadium + Sodium content in fuel exceeds 100ppm, supports to be either:
- 50Cr-50Ni metallurgy, without any coating
- Covered with 50 mm (2 in) of castable refractory (see API 560)

Notes
1. Environmentally friendly body-soluble fibre is the recommended choice for fire insulation
2. HW and MW Castable is strong enough to be used on floor without a top brick layer
3. Ceramic fibre insulation are typically used in all areas except stack and ducting.
4. Ceramic fibre not suitable for convection sections with sootblowers or steam lances are used for cleaning.
5. Vapour barrier protective coating is required behind all areas lined with ceramic fibre
6. SS foil barrier is required for ceramic fibre lined areas if the sulphur content exceeds 500ppm by mass.

Firing Notes
1. The Lower Heating Value (LHV) of the fuel efficiencies shall be used for efficiency calculations
2. Typical radiation heat loss value of 1.5% is used typically considered. However, in cases with a flue gas/air preheater, a value of 2.5% is normally considered.
3. Typical Excess Air values can be used as follows:
- Natural Draft - 15% excess air
- Forced Draft - 10% excess air
4. API 560 - Pressure at the Arch should be maintained at -2.5mmH2Og (-0.1inH2Og)
Tube Support Notes
1. Design temp. for tube supports should be Arch temp + 100 C (180 F)
2. No credit should be considered for shielding effect of tube supports by refractory
3. API 560 states if fuel the Vanadium + Sodium content in fuel exceeds 100ppm, supports to be either:
- 50Cr-50Ni metallurgy, without any coating
- Covered with 50 mm (2 in) of castable refractory (see API 560)

Notes
1. Environmentally friendly body-soluble fibre is the recommended choice for fire insulation
2. HW and MW Castable is strong enough to be used on floor without a top brick layer
3. Ceramic fibre insulation are typically used in all areas except stack and ducting.
4. Ceramic fibre not suitable for convection sections with sootblowers or steam lances are used for cleaning.
5. Vapour barrier protective coating is required behind all areas lined with ceramic fibre
6. SS foil barrier is required for ceramic fibre lined areas if the sulphur content exceeds 500ppm by mass.

Firing Notes
1. The Lower Heating Value (LHV) of the fuel efficiencies shall be used for efficiency calculations
2. Typical radiation heat loss value of 1.5% is used typically considered. However, in cases with a flue gas/air preheater, a value of 2.5% is normally considered.
3. Typical Excess Air values can be used as follows:
- Natural Draft - 15% excess air
- Forced Draft - 10% excess air
4. API 560 - Pressure at the Arch should be maintained at -2.5mmH2Og (-0.1inH2Og)
Tube Support Notes
1. Design temp. for tube supports should be Arch temp + 100 C (180 F)
2. No credit should be considered for shielding effect of tube supports by refractory
3. API 560 states if fuel the Vanadium + Sodium content in fuel exceeds 100ppm, supports to be either:
- 50Cr-50Ni metallurgy, without any coating
- Covered with 50 mm (2 in) of castable refractory (see API 560)

Notes
1. Environmentally friendly body-soluble fibre is the recommended choice for fire insulation
2. HW and MW Castable is strong enough to be used on floor without a top brick layer
3. Ceramic fibre insulation are typically used in all areas except stack and ducting.
4. Ceramic fibre not suitable for convection sections with sootblowers or steam lances are used for cleaning.
5. Vapour barrier protective coating is required behind all areas lined with ceramic fibre
6. SS foil barrier is required for ceramic fibre lined areas if the sulphur content exceeds 500ppm by mass.

Firing Notes
1. The Lower Heating Value (LHV) of the fuel efficiencies shall be used for efficiency calculations
2. Typical radiation heat loss value of 1.5% is used typically considered. However, in cases with a flue gas/air preheater, a value of 2.5% is normally considered.
3. Typical Excess Air values can be used as follows:
- Natural Draft - 15% excess air
- Forced Draft - 10% excess air
4. API 560 - Pressure at the Arch should be maintained at -2.5mmH2Og (-0.1inH2Og)
Tube Support Notes
1. Design temp. for tube supports should be Arch temp + 100 C (180 F)
2. No credit should be considered for shielding effect of tube supports by refractory
3. API 560 states if fuel the Vanadium + Sodium content in fuel exceeds 100ppm, supports to be either:
- 50Cr-50Ni metallurgy, without any coating
- Covered with 50 mm (2 in) of castable refractory (see API 560)

Notes
1. Environmentally friendly body-soluble fibre is the recommended choice for fire insulation
2. HW and MW Castable is strong enough to be used on floor without a top brick layer
3. Ceramic fibre insulation are typically used in all areas except stack and ducting.
4. Ceramic fibre not suitable for convection sections with sootblowers or steam lances are used for cleaning.
5. Vapour barrier protective coating is required behind all areas lined with ceramic fibre
6. SS foil barrier is required for ceramic fibre lined areas if the sulphur content exceeds 500ppm by mass.

Firing Notes
1. The Lower Heating Value (LHV) of the fuel efficiencies shall be used for efficiency calculations
2. Typical radiation heat loss value of 1.5% is used typically considered. However, in cases with a flue gas/air preheater, a value of 2.5% is normally considered.
3. Typical Excess Air values can be used as follows:
- Natural Draft - 15% excess air
- Forced Draft - 10% excess air
4. API 560 - Pressure at the Arch should be maintained at -2.5mmH2Og (-0.1inH2Og)
Tube Support Notes
1. Design temp. for tube supports should be Arch temp + 100 C (180 F)
2. No credit should be considered for shielding effect of tube supports by refractory
3. API 560 states if fuel the Vanadium + Sodium content in fuel exceeds 100ppm, supports to be either:
- 50Cr-50Ni metallurgy, without any coating
- Covered with 50 mm (2 in) of castable refractory (see API 560)

Notes
1. Environmentally friendly body-soluble fibre is the recommended choice for fire insulation
2. HW and MW Castable is strong enough to be used on floor without a top brick layer
3. Ceramic fibre insulation are typically used in all areas except stack and ducting.
4. Ceramic fibre not suitable for convection sections with sootblowers or steam lances are used for cleaning.
5. Vapour barrier protective coating is required behind all areas lined with ceramic fibre
6. SS foil barrier is required for ceramic fibre lined areas if the sulphur content exceeds 500ppm by mass.

Firing Notes
1. The Lower Heating Value (LHV) of the fuel efficiencies shall be used for efficiency calculations
2. Typical radiation heat loss value of 1.5% is used typically considered. However, in cases with a flue gas/air preheater, a value of 2.5% is normally considered.
3. Typical Excess Air values can be used as follows:
- Natural Draft - 15% excess air
- Forced Draft - 10% excess air
4. API 560 - Pressure at the Arch should be maintained at -2.5mmH2Og (-0.1inH2Og)
Tube Support Notes
1. Design temp. for tube supports should be Arch temp + 100 C (180 F)
2. No credit should be considered for shielding effect of tube supports by refractory
3. API 560 states if fuel the Vanadium + Sodium content in fuel exceeds 100ppm, supports to be either:
- 50Cr-50Ni metallurgy, without any coating
- Covered with 50 mm (2 in) of castable refractory (see API 560)

Notes
1. Environmentally friendly body-soluble fibre is the recommended choice for fire insulation
2. HW and MW Castable is strong enough to be used on floor without a top brick layer
3. Ceramic fibre insulation are typically used in all areas except stack and ducting.
4. Ceramic fibre not suitable for convection sections with sootblowers or steam lances are used for cleaning.
5. Vapour barrier protective coating is required behind all areas lined with ceramic fibre
6. SS foil barrier is required for ceramic fibre lined areas if the sulphur content exceeds 500ppm by mass.

Firing Notes
1. The Lower Heating Value (LHV) of the fuel efficiencies shall be used for efficiency calculations
2. Typical radiation heat loss value of 1.5% is used typically considered. However, in cases with a flue gas/air preheater, a value of 2.5% is normally considered.
3. Typical Excess Air values can be used as follows:
- Natural Draft - 15% excess air
- Forced Draft - 10% excess air
4. API 560 - Pressure at the Arch should be maintained at -2.5mmH2Og (-0.1inH2Og)
Tube Support Notes
1. Design temp. for tube supports should be Arch temp + 100 C (180 F)
2. No credit should be considered for shielding effect of tube supports by refractory
3. API 560 states if fuel the Vanadium + Sodium content in fuel exceeds 100ppm, supports to be either:
- 50Cr-50Ni metallurgy, without any coating
- Covered with 50 mm (2 in) of castable refractory (see API 560)

Notes
1. Environmentally friendly body-soluble fibre is the recommended choice for fire insulation
2. HW and MW Castable is strong enough to be used on floor without a top brick layer
3. Ceramic fibre insulation are typically used in all areas except stack and ducting.
4. Ceramic fibre not suitable for convection sections with sootblowers or steam lances are used for cleaning.
5. Vapour barrier protective coating is required behind all areas lined with ceramic fibre
6. SS foil barrier is required for ceramic fibre lined areas if the sulphur content exceeds 500ppm by mass.

Firing Notes
1. The Lower Heating Value (LHV) of the fuel efficiencies shall be used for efficiency calculations
2. Typical radiation heat loss value of 1.5% is used typically considered. However, in cases with a flue gas/air preheater, a value of 2.5% is normally considered.
3. Typical Excess Air values can be used as follows:
- Natural Draft - 15% excess air
- Forced Draft - 10% excess air
4. API 560 - Pressure at the Arch should be maintained at -2.5mmH2Og (-0.1inH2Og)
Tube Support Notes
1. Design temp. for tube supports should be Arch temp + 100 C (180 F)
2. No credit should be considered for shielding effect of tube supports by refractory
3. API 560 states if fuel the Vanadium + Sodium content in fuel exceeds 100ppm, supports to be either:
- 50Cr-50Ni metallurgy, without any coating
- Covered with 50 mm (2 in) of castable refractory (see API 560)

2. Typical radiation heat loss value of 1.5% is used typically considered. However, in cases with a flue gas/air preheater, a value of 2.5% is normally considered.
3. Typical Excess Air values can be used as follows:
- Natural Draft - 15% excess air
- Forced Draft - 10% excess air
4. API 560 - Pressure at the Arch should be maintained at -2.5mmH2Og (-0.1inH2Og)

Notes
1. Environmentally friendly body-soluble fibre is the recommended choice for fire insulation
2. HW and MW Castable is strong enough to be used on floor without a top brick layer
3. Ceramic fibre insulation are typically used in all areas except stack and ducting.
4. Ceramic fibre not suitable for convection sections with sootblowers or steam lances are used for cleaning.
5. Vapour barrier protective coating is required behind all areas lined with ceramic fibre
6. SS foil barrier is required for ceramic fibre lined areas if the sulphur content exceeds 500ppm by mass.

Firing Notes
1. The Lower Heating Value (LHV) of the fuel efficiencies shall be used for efficiency calculations
2. Typical radiation heat loss value of 1.5% is used typically considered. However, in cases with a flue gas/air preheater, a value of 2.5% is normally considered.
3. Typical Excess Air values can be used as follows:
- Natural Draft - 15% excess air
- Forced Draft - 10% excess air
4. API 560 - Pressure at the Arch should be maintained at -2.5mmH2Og (-0.1inH2Og)
Tube Support Notes
1. Design temp. for tube supports should be Arch temp + 100 C (180 F)
2. No credit should be considered for shielding effect of tube supports by refractory
3. API 560 states if fuel the Vanadium + Sodium content in fuel exceeds 100ppm, supports to be either:
- 50Cr-50Ni metallurgy, without any coating
- Covered with 50 mm (2 in) of castable refractory (see API 560)

Notes
1. Environmentally friendly body-soluble fibre is the recommended choice for fire insulation
2. HW and MW Castable is strong enough to be used on floor without a top brick layer
3. Ceramic fibre insulation are typically used in all areas except stack and ducting.
4. Ceramic fibre not suitable for convection sections with sootblowers or steam lances are used for cleaning.
5. Vapour barrier protective coating is required behind all areas lined with ceramic fibre
6. SS foil barrier is required for ceramic fibre lined areas if the sulphur content exceeds 500ppm by mass.

Firing Notes
1. The Lower Heating Value (LHV) of the fuel efficiencies shall be used for efficiency calculations
2. Typical radiation heat loss value of 1.5% is used typically considered. However, in cases with a flue gas/air preheater, a value of 2.5% is normally considered.
3. Typical Excess Air values can be used as follows:
- Natural Draft - 15% excess air
- Forced Draft - 10% excess air
4. API 560 - Pressure at the Arch should be maintained at -2.5mmH2Og (-0.1inH2Og)
Tube Support Notes
1. Design temp. for tube supports should be Arch temp + 100 C (180 F)
2. No credit should be considered for shielding effect of tube supports by refractory
3. API 560 states if fuel the Vanadium + Sodium content in fuel exceeds 100ppm, supports to be either:

2. One Pilot per burner is recommended
3. Electric spark ignition is recommended for each pilot
4. Forced draft system
Notes
1. The Lower Heating Value (LHV) of the fuel efficiencies shall be used for efficiency calculations
2. Typical radiation heat loss value of 1.5% is used typically considered. However, in cases with a flue gas/air preheater, a value of 2.5% is normally considered.
3. Typical Excess Air values can be used as follows:
- Natural Draft - 15% excess air
- Forced Draft - 10% excess air
4. API 560 - Pressure at the Arch should be maintained at -2.5mmH2Og (-0.1inH2Og)

Notes
1. Environmentally friendly body-soluble fibre is the recommended choice for fire insulation
2. HW and MW Castable is strong enough to be used on floor without a top brick layer
3. Ceramic fibre insulation are typically used in all areas except stack and ducting.
4. Ceramic fibre not suitable for convection sections with sootblowers or steam lances are used for cleaning.
5. Vapour barrier protective coating is required behind all areas lined with ceramic fibre
6. SS foil barrier is required for ceramic fibre lined areas if the sulphur content exceeds 500ppm by mass.

Firing Notes
1. The Lower Heating Value (LHV) of the fuel efficiencies shall be used for efficiency calculations
2. Typical radiation heat loss value of 1.5% is used typically considered. However, in cases with a flue gas/air preheater, a value of 2.5% is normally considered.
3. Typical Excess Air values can be used as follows:
- Natural Draft - 15% excess air
- Forced Draft - 10% excess air
4. API 560 - Pressure at the Arch should be maintained at -2.5mmH2Og (-0.1inH2Og)
Tube Support Notes
1. Design temp. for tube supports should be Arch temp + 100 C (180 F)
2. No credit should be considered for shielding effect of tube supports by refractory
3. API 560 states if fuel the Vanadium + Sodium content in fuel exceeds 100ppm, supports to be either:
- 50Cr-50Ni metallurgy, without any coating
- Covered with 50 mm (2 in) of castable refractory (see API 560)

Notes
1. Environmentally friendly body-soluble fibre is the recommended choice for fire insulation
2. HW and MW Castable is strong enough to be used on floor without a top brick layer
3. Ceramic fibre insulation are typically used in all areas except stack and ducting.
4. Ceramic fibre not suitable for convection sections with sootblowers or steam lances are used for cleaning.
5. Vapour barrier protective coating is required behind all areas lined with ceramic fibre
6. SS foil barrier is required for ceramic fibre lined areas if the sulphur content exceeds 500ppm by mass.

Firing Notes
1. The Lower Heating Value (LHV) of the fuel efficiencies shall be used for efficiency calculations
2. Typical radiation heat loss value of 1.5% is used typically considered. However, in cases with a flue gas/air preheater, a value of 2.5% is normally considered.
3. Typical Excess Air values can be used as follows:
- Natural Draft - 15% excess air
- Forced Draft - 10% excess air
4. API 560 - Pressure at the Arch should be maintained at -2.5mmH2Og (-0.1inH2Og)
Tube Support Notes
1. Design temp. for tube supports should be Arch temp + 100 C (180 F)
2. No credit should be considered for shielding effect of tube supports by refractory
3. API 560 states if fuel the Vanadium + Sodium content in fuel exceeds 100ppm, supports to be either:
- 50Cr-50Ni metallurgy, without any coating
- Covered with 50 mm (2 in) of castable refractory (see API 560)

1. One UV scanner per burner is recommended (if total no. burners < 20)
2. One Pilot per burner is recommended
3. Electric spark ignition is recommended for each pilot
4. Forced draft system
Notes
1. The Lower Heating Value (LHV) of the fuel efficiencies shall be used for efficiency calculations
2. Typical radiation heat loss value of 1.5% is used typically considered. However, in cases with a flue gas/air preheater, a value of 2.5% is normally considered.
3. Typical Excess Air values can be used as follows:
- Natural Draft - 15% excess air
- Forced Draft - 10% excess air
4. API 560 - Pressure at the Arch should be maintained at -2.5mmH2Og (-0.1inH2Og)

Notes
1. Environmentally friendly body-soluble fibre is the recommended choice for fire insulation
2. HW and MW Castable is strong enough to be used on floor without a top brick layer
3. Ceramic fibre insulation are typically used in all areas except stack and ducting.
4. Ceramic fibre not suitable for convection sections with sootblowers or steam lances are used for cleaning.
5. Vapour barrier protective coating is required behind all areas lined with ceramic fibre
6. SS foil barrier is required for ceramic fibre lined areas if the sulphur content exceeds 500ppm by mass.

Firing Notes
1. The Lower Heating Value (LHV) of the fuel efficiencies shall be used for efficiency calculations
2. Typical radiation heat loss value of 1.5% is used typically considered. However, in cases with a flue gas/air preheater, a value of 2.5% is normally considered.
3. Typical Excess Air values can be used as follows:
- Natural Draft - 15% excess air
- Forced Draft - 10% excess air
4. API 560 - Pressure at the Arch should be maintained at -2.5mmH2Og (-0.1inH2Og)
Tube Support Notes
1. Design temp. for tube supports should be Arch temp + 100 C (180 F)
2. No credit should be considered for shielding effect of tube supports by refractory
3. API 560 states if fuel the Vanadium + Sodium content in fuel exceeds 100ppm, supports to be either:
- 50Cr-50Ni metallurgy, without any coating
- Covered with 50 mm (2 in) of castable refractory (see API 560)

Notes
1. Environmentally friendly body-soluble fibre is the recommended choice for fire insulation
2. HW and MW Castable is strong enough to be used on floor without a top brick layer
3. Ceramic fibre insulation are typically used in all areas except stack and ducting.
4. Ceramic fibre not suitable for convection sections with sootblowers or steam lances are used for cleaning.
5. Vapour barrier protective coating is required behind all areas lined with ceramic fibre
6. SS foil barrier is required for ceramic fibre lined areas if the sulphur content exceeds 500ppm by mass.

Firing Notes
1. The Lower Heating Value (LHV) of the fuel efficiencies shall be used for efficiency calculations
2. Typical radiation heat loss value of 1.5% is used typically considered. However, in cases with a flue gas/air preheater, a value of 2.5% is normally considered.
3. Typical Excess Air values can be used as follows:
- Natural Draft - 15% excess air
- Forced Draft - 10% excess air
4. API 560 - Pressure at the Arch should be maintained at -2.5mmH2Og (-0.1inH2Og)
Tube Support Notes
1. Design temp. for tube supports should be Arch temp + 100 C (180 F)
2. No credit should be considered for shielding effect of tube supports by refractory
3. API 560 states if fuel the Vanadium + Sodium content in fuel exceeds 100ppm, supports to be either:
- 50Cr-50Ni metallurgy, without any coating
- Covered with 50 mm (2 in) of castable refractory (see API 560)

Notes
1. Environmentally friendly body-soluble fibre is the recommended choice for fire insulation
2. HW and MW Castable is strong enough to be used on floor without a top brick layer
3. Ceramic fibre insulation are typically used in all areas except stack and ducting.
4. Ceramic fibre not suitable for convection sections with sootblowers or steam lances are used for cleaning.
5. Vapour barrier protective coating is required behind all areas lined with ceramic fibre
6. SS foil barrier is required for ceramic fibre lined areas if the sulphur content exceeds 500ppm by mass.

2. Typical radiation heat loss value of 1.5% is used typically considered. However, in cases with a flue gas/air preheater, a value of 2.5% is normally considered.
3. Typical Excess Air values can be used as follows:
- Natural Draft - 15% excess air
- Forced Draft - 10% excess air
4. API 560 - Pressure at the Arch should be maintained at -2.5mmH2Og (-0.1inH2Og)
Tube Support Notes
1. Design temp. for tube supports should be Arch temp + 100 C (180 F)
2. No credit should be considered for shielding effect of tube supports by refractory
3. API 560 states if fuel the Vanadium + Sodium content in fuel exceeds 100ppm, supports to be either:
- 50Cr-50Ni metallurgy, without any coating
- Covered with 50 mm (2 in) of castable refractory (see API 560)

Notes
1. Environmentally friendly body-soluble fibre is the recommended choice for fire insulation
2. HW and MW Castable is strong enough to be used on floor without a top brick layer
3. Ceramic fibre insulation are typically used in all areas except stack and ducting.
4. Ceramic fibre not suitable for convection sections with sootblowers or steam lances are used for cleaning.
5. Vapour barrier protective coating is required behind all areas lined with ceramic fibre
6. SS foil barrier is required for ceramic fibre lined areas if the sulphur content exceeds 500ppm by mass.

Firing Notes
1. The Lower Heating Value (LHV) of the fuel efficiencies shall be used for efficiency calculations
2. Typical radiation heat loss value of 1.5% is used typically considered. However, in cases with a flue gas/air preheater, a value of 2.5% is normally considered.
3. Typical Excess Air values can be used as follows:
- Natural Draft - 15% excess air
- Forced Draft - 10% excess air
4. API 560 - Pressure at the Arch should be maintained at -2.5mmH2Og (-0.1inH2Og)
Tube Support Notes
1. Design temp. for tube supports should be Arch temp + 100 C (180 F)
2. No credit should be considered for shielding effect of tube supports by refractory
3. API 560 states if fuel the Vanadium + Sodium content in fuel exceeds 100ppm, supports to be either:
- 50Cr-50Ni metallurgy, without any coating
- Covered with 50 mm (2 in) of castable refractory (see API 560)

Notes
1. Environmentally friendly body-soluble fibre is the recommended choice for fire insulation
2. HW and MW Castable is strong enough to be used on floor without a top brick layer
3. Ceramic fibre insulation are typically used in all areas except stack and ducting.
4. Ceramic fibre not suitable for convection sections with sootblowers or steam lances are used for cleaning.
5. Vapour barrier protective coating is required behind all areas lined with ceramic fibre
6. SS foil barrier is required for ceramic fibre lined areas if the sulphur content exceeds 500ppm by mass.

Firing Notes
1. The Lower Heating Value (LHV) of the fuel efficiencies shall be used for efficiency calculations
2. Typical radiation heat loss value of 1.5% is used typically considered. However, in cases with a flue gas/air preheater, a value of 2.5% is normally considered.
3. Typical Excess Air values can be used as follows:
- Natural Draft - 15% excess air
- Forced Draft - 10% excess air
4. API 560 - Pressure at the Arch should be maintained at -2.5mmH₂Og (-0.1inH₂Og)
Tube Support Notes
1. Design temp. for tube supports should be Arch temp + 100 C (180 F)
2. No credit should be considered for shielding effect of tube supports by refractory
3. API 560 states if fuel the Vanadium + Sodium content in fuel exceeds 100ppm, supports to be either:
- 50Cr-50Ni metallurgy, without any coating
- Covered with 50 mm (2 in) of castable refractory (see API 560)

Notes
1. Environmentally friendly body-soluble fibre is the recommended choice for fire insulation
2. HW and MW Castable is strong enough to be used on floor without a top brick layer
3. Ceramic fibre insulation are typically used in all areas except stack and ducting.
4. Ceramic fibre not suitable for convection sections with sootblowers or steam lances are used for cleaning.
5. Vapour barrier protective coating is required behind all areas lined with ceramic fibre
6. SS foil barrier is required for ceramic fibre lined areas if the sulphur content exceeds 500ppm by mass.

Firing Notes
1. The Lower Heating Value (LHV) of the fuel efficiencies shall be used for efficiency calculations
2. Typical radiation heat loss value of 1.5% is used typically considered. However, in cases with a flue gas/air preheater, a value of 2.5% is normally considered.
3. Typical Excess Air values can be used as follows:
- Natural Draft - 15% excess air
- Forced Draft - 10% excess air
4. API 560 - Pressure at the Arch should be maintained at -2.5mmH₂Og (-0.1inH₂Og)
Tube Support Notes
1. Design temp. for tube supports should be Arch temp + 100 C (180 F)
2. No credit should be considered for shielding effect of tube supports by refractory
3. API 560 states if fuel the Vanadium + Sodium content in fuel exceeds 100ppm, supports to be either:
- 50Cr-50Ni metallurgy, without any coating
- Covered with 50 mm (2 in) of castable refractory (see API 560)

Notes
1. Environmentally friendly body-soluble fibre is the recommended choice for fire insulation
2. HW and MW Castable is strong enough to be used on floor without a top brick layer
3. Ceramic fibre insulation are typically used in all areas except stack and ducting.
4. Ceramic fibre not suitable for convection sections with sootblowers or steam lances are used for cleaning.
5. Vapour barrier protective coating is required behind all areas lined with ceramic fibre
6. SS foil barrier is required for ceramic fibre lined areas if the sulphur content exceeds 500ppm by mass.

Firing Notes
1. The Lower Heating Value (LHV) of the fuel efficiencies shall be used for efficiency calculations
2. Typical radiation heat loss value of 1.5% is used typically considered. However, in cases with a flue gas/air preheater, a value of 2.5% is normally considered.
3. Typical Excess Air values can be used as follows:
- Natural Draft - 15% excess air
- Forced Draft - 10% excess air
4. API 560 - Pressure at the Arch should be maintained at -2.5mmH₂Og (-0.1inH₂Og)
Tube Support Notes
1. Design temp. for tube supports should be Arch temp + 100 C (180 F)
2. No credit should be considered for shielding effect of tube supports by refractory
3. API 560 states if fuel the Vanadium + Sodium content in fuel exceeds 100ppm, supports to be either:
- 50Cr-50Ni metallurgy, without any coating
- Covered with 50 mm (2 in) of castable refractory (see API 560)

Notes
1. Environmentally friendly body-soluble fibre is the recommended choice for fire insulation
2. HW and MW Castable is strong enough to be used on floor without a top brick layer
3. Ceramic fibre insulation are typically used in all areas except stack and ducting.
4. Ceramic fibre not suitable for convection sections with sootblowers or steam lances are used for cleaning.
5. Vapour barrier protective coating is required behind all areas lined with ceramic fibre
6. SS foil barrier is required for ceramic fibre lined areas if the sulphur content exceeds 500ppm by mass.

Firing Notes
1. The Lower Heating Value (LHV) of the fuel efficiencies shall be used for efficiency calculations
2. Typical radiation heat loss value of 1.5% is used typically considered. However, in cases with a flue gas/air preheater, a value of 2.5% is normally considered.
3. Typical Excess Air values can be used as follows:
- Natural Draft - 15% excess air
- Forced Draft - 10% excess air
4. API 560 - Pressure at the Arch should be maintained at -2.5mmH2Og (-0.1inH2Og)
Tube Support Notes
1. Design temp. for tube supports should be Arch temp + 100 C (180 F)
2. No credit should be considered for shielding effect of tube supports by refractory
3. API 560 states if fuel the Vanadium + Sodium content in fuel exceeds 100ppm, supports to be either:
- 50Cr-50Ni metallurgy, without any coating
- Covered with 50 mm (2 in) of castable refractory (see API 560)

Notes
1. Environmentally friendly body-soluble fibre is the recommended choice for fire insulation
2. HW and MW Castable is strong enough to be used on floor without a top brick layer
3. Ceramic fibre insulation are typically used in all areas except stack and ducting.
4. Ceramic fibre not suitable for convection sections with sootblowers or steam lances are used for cleaning.
5. Vapour barrier protective coating is required behind all areas lined with ceramic fibre
6. SS foil barrier is required for ceramic fibre lined areas if the sulphur content exceeds 500ppm by mass.

Firing Notes
1. The Lower Heating Value (LHV) of the fuel efficiencies shall be used for efficiency calculations
2. Typical radiation heat loss value of 1.5% is used typically considered. However, in cases with a flue gas/air preheater, a value of 2.5% is normally considered.
3. Typical Excess Air values can be used as follows:
- Natural Draft - 15% excess air
- Forced Draft - 10% excess air
4. API 560 - Pressure at the Arch should be maintained at -2.5mmH2Og (-0.1inH2Og)
Tube Support Notes
1. Design temp. for tube supports should be Arch temp + 100 C (180 F)
2. No credit should be considered for shielding effect of tube supports by refractory
3. API 560 states if fuel the Vanadium + Sodium content in fuel exceeds 100ppm, supports to be either:
- 50Cr-50Ni metallurgy, without any coating
- Covered with 50 mm (2 in) of castable refractory (see API 560)

Notes
1. Environmentally friendly body-soluble fibre is the recommended choice for fire insulation
2. HW and MW Castable is strong enough to be used on floor without a top brick layer
3. Ceramic fibre insulation are typically used in all areas except stack and ducting.
4. Ceramic fibre not suitable for convection sections with sootblowers or steam lances are used for cleaning.
5. Vapour barrier protective coating is required behind all areas lined with ceramic fibre
6. SS foil barrier is required for ceramic fibre lined areas if the sulphur content exceeds 500ppm by mass.

Firing Notes
1. The Lower Heating Value (LHV) of the fuel efficiencies shall be used for efficiency calculations
2. Typical radiation heat loss value of 1.5% is used typically considered. However, in cases with a flue gas/air preheater, a value of 2.5% is normally considered.
3. Typical Excess Air values can be used as follows:
- Natural Draft - 15% excess air
- Forced Draft - 10% excess air
4. API 560 - Pressure at the Arch should be maintained at -2.5mmH2Og (-0.1inH2Og)
Tube Support Notes
1. Design temp. for tube supports should be Arch temp + 100 C (180 F)
2. No credit should be considered for shielding effect of tube supports by refractory
3. API 560 states if fuel the Vanadium + Sodium content in fuel exceeds 100ppm, supports to be either:
- 50Cr-50Ni metallurgy, without any coating
- Covered with 50 mm (2 in) of castable refractory (see API 560)

Notes
1. Environmentally friendly body-soluble fibre is the recommended choice for fire insulation
2. HW and MW Castable is strong enough to be used on floor without a top brick layer
3. Ceramic fibre insulation are typically used in all areas except stack and ducting.
4. Ceramic fibre not suitable for convection sections with sootblowers or steam lances are used for cleaning.
5. Vapour barrier protective coating is required behind all areas lined with ceramic fibre
6. SS foil barrier is required for ceramic fibre lined areas if the sulphur content exceeds 500ppm by mass.

Firing Notes
1. The Lower Heating Value (LHV) of the fuel efficiencies shall be used for efficiency calculations
2. Typical radiation heat loss value of 1.5% is used typically considered. However, in cases with a flue gas/air preheater, a value of 2.5% is normally considered.
3. Typical Excess Air values can be used as follows:
- Natural Draft - 15% excess air
- Forced Draft - 10% excess air
4. API 560 - Pressure at the Arch should be maintained at -2.5mmH2Og (-0.1inH2Og)
Tube Support Notes
1. Design temp. for tube supports should be Arch temp + 100 C (180 F)
2. No credit should be considered for shielding effect of tube supports by refractory
3. API 560 states if fuel the Vanadium + Sodium content in fuel exceeds 100ppm, supports to be either:
- 50Cr-50Ni metallurgy, without any coating
- Covered with 50 mm (2 in) of castable refractory (see API 560)

Notes
1. Environmentally friendly body-soluble fibre is the recommended choice for fire insulation
2. HW and MW Castable is strong enough to be used on floor without a top brick layer
3. Ceramic fibre insulation are typically used in all areas except stack and ducting.
4. Ceramic fibre not suitable for convection sections with sootblowers or steam lances are used for cleaning.
5. Vapour barrier protective coating is required behind all areas lined with ceramic fibre
6. SS foil barrier is required for ceramic fibre lined areas if the sulphur content exceeds 500ppm by mass.

Firing Notes
1. The Lower Heating Value (LHV) of the fuel efficiencies shall be used for efficiency calculations
2. Typical radiation heat loss value of 1.5% is used typically considered. However, in cases with a flue gas/air preheater, a value of 2.5% is normally considered.
3. Typical Excess Air values can be used as follows:
- Natural Draft - 15% excess air
- Forced Draft - 10% excess air
4. API 560 - Pressure at the Arch should be maintained at -2.5mmH₂Og (-0.1inH₂Og)
Tube Support Notes
1. Design temp. for tube supports should be Arch temp + 100 C (180 F)
2. No credit should be considered for shielding effect of tube supports by refractory
3. API 560 states if fuel the Vanadium + Sodium content in fuel exceeds 100ppm, supports to be either:
- 50Cr-50Ni metallurgy, without any coating
- Covered with 50 mm (2 in) of castable refractory (see API 560)

Notes
1. Environmentally friendly body-soluble fibre is the recommended choice for fire insulation
2. HW and MW Castable is strong enough to be used on floor without a top brick layer
3. Ceramic fibre insulation are typically used in all areas except stack and ducting.
4. Ceramic fibre not suitable for convection sections with sootblowers or steam lances are used for cleaning.
5. Vapour barrier protective coating is required behind all areas lined with ceramic fibre
6. SS foil barrier is required for ceramic fibre lined areas if the sulphur content exceeds 500ppm by mass.

Firing Notes
1. The Lower Heating Value (LHV) of the fuel efficiencies shall be used for efficiency calculations
2. Typical radiation heat loss value of 1.5% is used typically considered. However, in cases with a flue gas/air preheater, a value of 2.5% is normally considered.
3. Typical Excess Air values can be used as follows:
- Natural Draft - 15% excess air
- Forced Draft - 10% excess air
4. API 560 - Pressure at the Arch should be maintained at -2.5mmH₂Og (-0.1inH₂Og)
Tube Support Notes
1. Design temp. for tube supports should be Arch temp + 100 C (180 F)
2. No credit should be considered for shielding effect of tube supports by refractory
3. API 560 states if fuel the Vanadium + Sodium content in fuel exceeds 100ppm, supports to be either:
- 50Cr-50Ni metallurgy, without any coating
- Covered with 50 mm (2 in) of castable refractory (see API 560)

Notes
1. One UV scanner per burner is recommended (if total no. burners < 20)
2. One Pilot per burner is recommended
3. Electric spark ignition is recommended for each pilot
4. Forced draft system
Notes
1. The Lower Heating Value (LHV) of the fuel efficiencies shall be used for efficiency calculations
2. Typical radiation heat loss value of 1.5% is used typically considered. However, in cases with a flue gas/air preheater, a value of 2.5% is normally considered.
3. Typical Excess Air values can be used as follows:
- Natural Draft - 15% excess air
- Forced Draft - 10% excess air
4. API 560 - Pressure at the Arch should be maintained at -2.5mmH₂Og (-0.1inH₂Og)

Notes
1. Environmentally friendly body-soluble fibre is the recommended choice for fire insulation
2. HW and MW Castable is strong enough to be used on floor without a top brick layer
3. Ceramic fibre insulation are typically used in all areas except stack and ducting.
4. Ceramic fibre not suitable for convection sections with sootblowers or steam lances are used for cleaning.
5. Vapour barrier protective coating is required behind all areas lined with ceramic fibre
6. SS foil barrier is required for ceramic fibre lined areas if the sulphur content exceeds 500ppm by mass.

Firing Notes
1. The Lower Heating Value (LHV) of the fuel efficiencies shall be used for efficiency calculations
2. Typical radiation heat loss value of 1.5% is used typically considered. However, in cases with a flue gas/air preheater, a value of 2.5% is normally considered.
3. Typical Excess Air values can be used as follows:
- Natural Draft - 15% excess air
- Forced Draft - 10% excess air
4. API 560 - Pressure at the Arch should be maintained at -2.5mmH₂Og (-0.1inH₂Og)
Tube Support Notes
1. Design temp. for tube supports should be Arch temp + 100 C (180 F)
2. No credit should be considered for shielding effect of tube supports by refractory
3. API 560 states if fuel the Vanadium + Sodium content in fuel exceeds 100ppm, supports to be either:
- 50Cr-50Ni metallurgy, without any coating
- Covered with 50 mm (2 in) of castable refractory (see API 560)

Notes
1. Environmentally friendly body-soluble fibre is the recommended choice for fire insulation
2. HW and MW Castable is strong enough to be used on floor without a top brick layer
3. Ceramic fibre insulation are typically used in all areas except stack and ducting.
4. Ceramic fibre not suitable for convection sections with sootblowers or steam lances are used for cleaning.
5. Vapour barrier protective coating is required behind all areas lined with ceramic fibre
6. SS foil barrier is required for ceramic fibre lined areas if the sulphur content exceeds 500ppm by mass.

Firing Notes
1. The Lower Heating Value (LHV) of the fuel efficiencies shall be used for efficiency calculations
2. Typical radiation heat loss value of 1.5% is used typically considered. However, in cases with a flue gas/air preheater, a value of 2.5% is normally considered.
3. Typical Excess Air values can be used as follows:
- Natural Draft - 15% excess air
- Forced Draft - 10% excess air
4. API 560 - Pressure at the Arch should be maintained at -2.5mmH₂Og (-0.1inH₂Og)
Tube Support Notes
1. Design temp. for tube supports should be Arch temp + 100 C (180 F)
2. No credit should be considered for shielding effect of tube supports by refractory
3. API 560 states if fuel the Vanadium + Sodium content in fuel exceeds 100ppm, supports to be either:
- 50Cr-50Ni metallurgy, without any coating
- Covered with 50 mm (2 in) of castable refractory (see API 560)

Notes
1. Environmentally friendly body-soluble fibre is the recommended choice for fire insulation
2. HW and MW Castable is strong enough to be used on floor without a top brick layer
3. Ceramic fibre insulation are typically used in all areas except stack and ducting.
4. Ceramic fibre not suitable for convection sections with sootblowers or steam lances are used for cleaning.
5. Vapour barrier protective coating is required behind all areas lined with ceramic fibre
6. SS foil barrier is required for ceramic fibre lined areas if the sulphur content exceeds 500ppm by mass.

Firing Notes
1. The Lower Heating Value (LHV) of the fuel efficiencies shall be used for efficiency calculations
2. Typical radiation heat loss value of 1.5% is used typically considered. However, in cases with a flue gas/air preheater, a value of 2.5% is normally considered.
3. Typical Excess Air values can be used as follows:
- Natural Draft - 15% excess air
- Forced Draft - 10% excess air
4. API 560 - Pressure at the Arch should be maintained at -2.5mmH2Og (-0.1inH2Og)
Tube Support Notes
1. Design temp. for tube supports should be Arch temp + 100 C (180 F)
2. No credit should be considered for shielding effect of tube supports by refractory
3. API 560 states if fuel the Vanadium + Sodium content in fuel exceeds 100ppm, supports to be either:
- 50Cr-50Ni metallurgy, without any coating
- Covered with 50 mm (2 in) of castable refractory (see API 560)

Notes
1. Environmentally friendly body-soluble fibre is the recommended choice for fire insulation
2. HW and MW Castable is strong enough to be used on floor without a top brick layer
3. Ceramic fibre insulation are typically used in all areas except stack and ducting.
4. Ceramic fibre not suitable for convection sections with sootblowers or steam lances are used for cleaning.
5. Vapour barrier protective coating is required behind all areas lined with ceramic fibre
6. SS foil barrier is required for ceramic fibre lined areas if the sulphur content exceeds 500ppm by mass.

Firing Notes
1. The Lower Heating Value (LHV) of the fuel efficiencies shall be used for efficiency calculations
2. Typical radiation heat loss value of 1.5% is used typically considered. However, in cases with a flue gas/air preheater, a value of 2.5% is normally considered.
3. Typical Excess Air values can be used as follows:
- Natural Draft - 15% excess air
- Forced Draft - 10% excess air
4. API 560 - Pressure at the Arch should be maintained at -2.5mmH₂Og (-0.1inH₂Og)
Tube Support Notes
1. Design temp. for tube supports should be Arch temp + 100 C (180 F)
2. No credit should be considered for shielding effect of tube supports by refractory
3. API 560 states if fuel the Vanadium + Sodium content in fuel exceeds 100ppm, supports to be either:
- 50Cr-50Ni metallurgy, without any coating
- Covered with 50 mm (2 in) of castable refractory (see API 560)

1. One UV scanner per burner is recommended (if total no. burners < 20)
2. One Pilot per burner is recommended
3. Electric spark ignition is recommended for each pilot
4. Forced draft system
Notes
1. The Lower Heating Value (LHV) of the fuel efficiencies shall be used for efficiency calculations
2. Typical radiation heat loss value of 1.5% is used typically considered. However, in cases with a flue gas/air preheater, a value of 2.5% is normally considered.
3. Typical Excess Air values can be used as follows:
- Natural Draft - 15% excess air
- Forced Draft - 10% excess air
4. API 560 - Pressure at the Arch should be maintained at -2.5mmH₂Og (-0.1inH₂Og)

Notes
1. Environmentally friendly body-soluble fibre is the recommended choice for fire insulation
2. HW and MW Castable is strong enough to be used on floor without a top brick layer
3. Ceramic fibre insulation are typically used in all areas except stack and ducting.
4. Ceramic fibre not suitable for convection sections with sootblowers or steam lances are used for cleaning.
5. Vapour barrier protective coating is required behind all areas lined with ceramic fibre
6. SS foil barrier is required for ceramic fibre lined areas if the sulphur content exceeds 500ppm by mass.
