ABSTRACT:
A combined gas/steam power plant includes a gas turbine power set for delivering power such as for driving an electrical generator which comprises a combustion chamber, a gas turbine and a compressor driven by it, and a steam power plant comprising a steam generator and a steam turbine for delivering power such as for driving another electrical generator. Gas generators produce fuel gas for firing the combustion chamber and steam generator respectively. Independent charging groups, each comprising a gas turbine and compressor, are provided for the combustion chamber and steam generator respectively. Gasification air for generating the portion of fuel gas supplied to the combustion chamber is taken from the combustion air conveyed by the compressor of the gas turbine power set and compressed further in the compressor of the charging group allocated to the combustion chamber up to the pressure prevailing in the appertaining fuel gas generator. Gasification air for generating the portion of fuel gas supplied to the steam generator is compressed in the compressor of the other charging group allocated to the steam generator from ambient pressure up to the pressure prevailing in the appertaining fuel gas generator, and the two portions of the fuel gas are passed through the gas turbines of their respective charging groups and thence to the combustion chamber and steam generator. In addition, the steam generator, which is not supercharged, is connected directly to the outlet of the power delivering gas turbine.
