ABSTRACT:
A gas and steam turbine plant includes a coal gasification plant, a gas turbine connected downstream of the coal gasification plant, a steam turbine having a water-steam loop and a steam generator connected downstream of the gas turbine. The steam generator includes a preheater connected to the water-steam loop, a heater of a high-pressure stage connected downstream of the preheater, and a heater of a low-pressure stage connected upstream of the preheater. An outflow line leads into the coal gasification plant and is connected to the water-steam loop downstream of the preheater, as seen in water flow direction. A heat exchanger has a primary side integrated with the water-steam loop between the low-pressure stage and the high-pressure stage and a secondary side connected parallel to the outflow line.
