ABSTRACT:
A process for the production of power from a carbonaceous fuel comprising the steps of partially oxidizing the fuel with oxygen or an oxygen-containing gas to yield a gas stream containing combustible gas and steam, quenching that stream with quench water to cool and saturate the stream, passing the stream (A) through a heat exchanger in which the stream is further cooled by heat exchange with circulating water so condensing liquid water from the stream, expanding the stream (D) by lowering its pressure and removing sulphur compounds from the stream before or after lowering its pressure, heating and resaturating the steam (E), and then burning the stream (F) in a gas turbine to produce power, wherein it is the circulating water aforesaid which is used to provide the heat for resaturating the stream.
