Four Foster Wheeler single drum boilers generate steam for LNG Plants Trains 1&2.
Each boiler has a capacity of 360,000 Kg/h at M.C.R.
The boilers are natural gas fired with a design pressure of 76.5 barg.
Each boiler has two sections: the furnace and the heat recovery area.
Burners are arranged in three horizontal rows on the front wall of the furnace.
Accessories include forced draught fans, boiler feed water pumps, feed heaters, and seal air fans.
Steam is supplied at 62.0 barg and 4400C to drive two steam turbine generators and process Train-1&2 compressors.
The boilers are operated in pairs.
Fuel is natural gas and routed through knock out drums.
Three element feed water, fuel combustion, and steam temperature controls are provided.
Each burner has a manual air register and tertiary air damper.
Airflow from fans is metered, indicated, and recorded.
Seal air fans inject sealing air to pilot burners and flame detectors.
Boiler feed water system is a closed loop system.
Deaerators remove dissolved oxygen and carbon dioxide gases from feed water.
DEHA and ammonia solution are injected for scavenging oxygen.
Six boiler feed pumps are arranged in two sets of three pumps each.
Steam is supplied from boilers at 62 barg pressure and 4400C temperature.
High-pressure steam is supplied to two cross-connected headers.
Major users of high-pressure steam include process trains, compressors, and utilities.
