Abstract: A gas and steam turbine plant includes a waste-heat steam generator which is located downstream of a gas turbine on the flue-gas side and which has heating surfaces that are connected into a water/steam circuit of a steam turbine. A gasification device is located upstream of a combustion chamber of the gas turbine through a fuel line, for the integrated gasification of a fossil fuel. The gas and steam turbine plant is to be operated with particularly high plant efficiency even when oil is used as the fossil fuel. Thus, a heat exchanger is connected on the primary side into the fuel line upstream of a mixing apparatus for admixing nitrogen to the gasified fuel, as seen in the direction of flow of the gasified fuel. The heat exchanger is constructed on the secondary side as an evaporator for a flow medium.

Abstract: A gas and steam-turbine plant includes a heat-recovery steam generator which is connected downstream of a gas turbine on the flue-gas side and has heating surfaces connected in a water/steam circuit of a steam turbine. A gasifier is connected upstream of a combustion chamber of the gas turbine for integrated gasification of a fossil fuel. Oxygen can be fed to the gasifier from an air-separation unit, to which in turn a partial flow of air compressed in an air compressor associated with the gas turbine can be admitted on the inlet side. In such a gas and steam-turbine plant, reliable cooling of the bleed air, in an especially simple type of construction, is to be ensured in all operating states, irrespective of the integration concept which is taken as a basis. Therefore, a heat exchanger for cooling the partial flow of compressed air is connected on the primary side in a bleed-air line connecting the air compressor to the air-separation unit.

Abstract: A gas turbine and steam turbine installation has a waste-heat steam generator whose heating surfaces are connected into the water/steam cycle of the steam turbine. A gasification device is connected upstream of the gas turbine in order to provide an integrated gasification of a fossil fuel. Reliable operation of a saturator which is connected into a fuel line is ensured independently of the operating condition of the gasification device.

Thus it is possible to heat the feed water cooled in the saturator-water heat exchanger through the use of a partial flow of compressed air, and it is possible to supply the partial flow of compressed air to an air separation unit connected upstream of the gasification device.
