METHOD FOR INCREASING THE EFFICIENCY OF A COMBINED GAS/STEAM POWER STATION WITH INTEGRATED GASIFICATION COMBINED CYCLE
摘要
The invention relates to a method for increasing the efficiency of a combined gas/steam power station (10) with integrated gasification combined cycle. Said power station comprises a gas turbine compressor (14) and an air-separation unit (18) having a defined working pressure. Compressed air is removed from the gas turbine compressor (14) at a pressure level that is adapted to the working pressure of the air-separation unit (18). The removed air is then supplied to the air-separation unit (18) where the air is broken down into its individual constituents, especially oxygen and nitrogen. The nitrogen produced in the air-separation unit (18) is removed from the air-separation unit and at least a part of the removed nitrogen quantity is used as a coolant in the gas/steam power station in order to improve its efficiency.
