METHOD FOR OPERATING A POWER STATION WITH INTEGRATED COAL GASIFICATION AND POWER STATION

摘要

The invention relates to a method for operating a power station with integrated coal gasification (2), in which a fossil fuel (B) is gasified and, as a synthetic gas (SG), is fed to a burner (7) of a gas turbine for combustion, wherein oxygen (02) is separated from air (L) by means of a membrane (17) at a process temperature (T), wherein the separated oxygen (02) is fed to the gasification device (2) to react with the fossil fuel (B), wherein heat energy is fed in for maintaining the necessary process temperature (T) of the membrane (17), wherein the heat energy is extracted from the synthetic gas (SG) by heat exchange with the air (L), and the heated air (L) is fed to the membrane.
