ABSTRACT:
Combined gas turbine/steam turbine plant, in which the exhaust gas line of the gas turbine block containing an air compressor, combustion chamber, gas turbine and generator is connected on the primary side to a steam generator which, in turn, comprises parts of the steam turbine block which also contains a high pressure and a low pressure turbine, a condenser, a feedwater tank and a feedwater pump. The combustion chamber of the gas turbine block is connected to the output of a coal gasification plant, the air separation unit which has an outlet for the separated nitrogen and the gasifier. The gasifier is followed by a steam generator for utilizing the raw gas heat and a heat exchanger for heating the purified gas by the raw gas. The steam generator arranged ahead of the raw gas/purified gas heat exchanger is designed as a high pressure steam generator, the secondary output of which is connected to the output of the steam generator of the steam turbine block. The raw-gas/purified-gas heat exchanger is followed by a low pressure steam generator, the secondary output of which is connected to the low pressure part of the steam turbine. The nitrogen outlet of the air separation unit located in the coal gasification plant is connected exclusively to the purified gas line leading to the combustion chamber or to the burners in the combustion chamber.
