| 摘要 |
The invention relates to a process for generating electrical energy in a gas and steam turbine (combined cycle) power generating plant with a gasification gas produced from carbon carriers and oxygen-containing gas, in which .cndot. the carbon carriers are gasified in a gassing zone with oxygen or a gas containing a large amount of oxygen, with an oxygen content of at least 95% by volume, preferably at least 99% by volume, .cndot. the gasification gas produced in this way is passed through a desulfurizing zone containing a desulfurizing agent, used desulfurizing agent being fed into the gassing zone and drawn off after the formation of a liquid slag, .cndot. the desulfurized gasification gas, preferably following cleaning and cooling, is burned in a combustion chamber together with pure oxygen and the resulting combustion gases H2O and CO2 are introduced into the gas turbine for energy generation, .cndot. downstream of the gas turbine, the combustion gases are separated in a steam boiler into water vapor and carbon dioxide, .cndot. the water vapor is subsequently introduced into a steam turbine, and .cndot. the carbon dioxide is at least partially returned to the combustion chamber for setting the temperatur |
