Abstract
A gas and steam turbine plant includes a steam turbine having a water-steam loop. A waste heat boiler which is connected downstream of a gas turbine includes a high-pressure preheater connected in the water-steam loop, a high-pressure heater connected downstream of the high-pressure preheater, a low-pressure heater connected upstream of the high-pressure preheater, and an evaporator of a medium-pressure heater. A coal gasification plant is connected upstream of the gas turbine. An outflow line leads into the coal gasification plant and is connected to the water-steam loop downstream of the high-pressure preheater, as seen in water flow direction. A water-steam drum communicates with the outflow line and is connected to the evaporator.
