Heat to the steam system is provided by the flue gas from the gas turbine to the heat recovery steam generator (HRSG) and by the cooling of the fuel gas. The flue gas from the HRSG can be used to dry the fuel in an integrated dryer. 

The hot flue gas from the gas turbine is ducted to the heat recovery steam generator (HRSG), where the steam generated, along with steam from the gas cooler, is super-heated and is then supplied to a steam turbine (40 bar, 455 C), generating 1.8 MWc. 

Heat recovery for large systems is accomplished by means of a boiler (commonly referred to as a "heat recovery steam generator" [HRSG]). Smaller systems utilize either a steam or hot water boiler, or alternatively, some type of air-fo-air heaf exchanger.
