A steam boiler system includes a steam air preheater disposed in inlet ducting for preheating intake air. A boiler feed pump provides high-pressure water to a boiler which in turn produces steam to drive a main turbine. Exhaust flow from the turbine is routed directly to a main condenser, with the exception of a small extraction flow which is used to drive a boiler feed pump turbine.

Auxiliary boiler is used to provide the plant with saturated steam. It is used whenever there is a water demand and no or low electricity demand. Also it is used when there is maintenance on the waste heat recovery boiler. The main components are the FD fan (force draught fan), burners, upper and lower drums, downcomers and risers (evaporator), the economizer and the feedwater.
