Abstract
In a method for operating a combined cycle power plant with coal or oil gasification, wherein the oxygen required for gasification is supplied by an air separation plant, the air required for the air separation plant is condensed in a first, separate condenser and is cooled in a heat exchanger prior to being supplied to the air separation plant. Only enough nitrogen produced in the separation plant is supplied to the gas turbine combustion chamber as the surge limit of the compressor permits. The remaining portion of the nitrogen is expanded to ambient pressure in an expander after exiting the air separation plant.
