Abstract
Combined gas-steam power plant, including a device for carrying out a gasification reaction at overpressure between oxygen and fuel fed to the gasification device, a heat exchanger and a charged steam generator disposed down stream of the gasification device in flow direction of fuel gas generated by the gasification device, a gas turbine receiving a flue gas stream from the steam generator, an air decomposition device having a first outlet line carrying oxygen to the gasification device and a second outlet line carrying nitrogen through the heat exchanger to the gas stream between the steam generator and gas turbine.
Claims4
Combined gas-steam power plant, comprising means for carrying out a gasification reaction at overpressure between oxygen and fuel fed to said gasification means, a heat exchanger and a charged steam generator disposed down stream of said gasification means in flow direction of fuel gas generated by said gasification means, a gas turbine receiving a flue gas stream from said steam generator, an air decomposition device having a first outlet line carrying oxygen to said gasification means and a second outlet line carrying nitrogen through said heat exchanger to said gas stream between said steam generator and gas turbine.
