Abstract
The invention relates to a method for generating electric energy in a gas/steam turbine power plant using a gasification gas produced by carbon carriers and oxygen-containing gas, wherein the carbon carriers are gasified in a melt gas zone with oxygen or a highly oxygenous gas that has an oxygen content of at least 95% by volume, preferably at least 99 % by volume. The inventive method includes the following steps: the produced gasification gas is passed through a desulfurization zone containing desulfurizing agents, wherein used desulfurizing agents are loaded into the melting-gasifying zone and withdrawn therefrom after formation of a liquid slag; the desulfurized gasification gas, preferably after having been cleaned and cooled, is then burnt together with pure oxygen in a combustion chamber; the resulting combustion gases, HO and CO, are conducted into the gas tubine for generating energy; after having passed the combustion chamber, the combustion gases are separated in a steam boiler into water vapour and carbon dioxide; the water vapour is subsequently guided into a steam turbine and the carbon dioxide is at least partially recirculated into the combustion chamber for temperature regulation.
