| 摘要 |
The invention relates to a method for generating electric energy in a gas /steam turbine power plant using a gasification gas produced by carbon carri ers 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 cont ent of at least 95% by volume, preferably at least 99% by volume. The invent ive method includes the following steps: the produced gasification gas is pa ssed through a desulfurization zone containing desulfurizing agents, wherein used desulfurizing agents are loaded into the melting-gasifying zone and wi thdrawn therefrom after formation of a liquid slag; the desulfurized gasific ation gas, preferably after having been cleaned and cooled, is then burnt to gether with pure oxygen in a combustion chamber; the resulting combustion ga ses, H2O and CO2, are conducted into the gas tubine for generating energy; a fter having passed the combustion chamber, the combustion gases are separate d in a steam boiler into water vapour and carbon dioxide; the water vapour i s subsequently guided into a steam turbine and the carbon dioxide is at leas t partially recirculated into the combustion chamber for temperature regulat ion. |
