In a combined-cycle turbine power station, a fluidised-bed boiler (30) is connected to the coal gasifier (1); part of the fluidised-bed material from the gasifier (1) is extracted and burned in this boiler. In the boiler (30), whose flue gases are passed to the coal gasifier (1), part of the steam for the steam-turbine set (3, 32 to 35, 41) is generated. The rest of the steam comes from a boiler (15) that is heated by the hot combustion gases coming from the coal gasifier (1), or from a waste-heat boiler (26) heated by the exhaust gases from the gas turbine (23). A sulphur scrubbing vessel (9), which is provided with calcined desulphurising additives from a fluidised-bed furnace (10) heated by the combustion gases, is connected downstream of the coal gasifier (1). <IMAGE> |
