ABSTRACT:
A process for operating a combined gas turbine/steam turbine power plant having an integrated partial fuel-combustion process is disclosed wherein a portion of a supply of compressed air is fed to a combustion reactor in which a fuel is gasified. The gasified fuel is combusted to drive a gas turbine with the discharge from the gas turbine heating a waste heat steam generator. Steam is generated in a boiler heated by the gasified fuel and drives a steam turbine. The steam is saturated in the boiler and is dried and heated in a heat exchanger arranged downstream of the boiler and upstream of the waste heat steam generator. The heat exchanger is heated by the portion of the compressed air with the air further compressed immediately downstream of the heat exchanger.
