Abstract
In a method for operating a gas turbine () in a combined cycle power plant (), air, which is used to burn a syngas that is recovered from coal, is drawn in and compressed by the gas turbine (), the compressed air is fed into a combustor () and such that a portion of the compressed air is separated into oxygen and nitrogen. An improved degree of efficiency is achieved by this method by virtue of the fact that a gas turbine () with reheating and two combustors () and two turbines () is used. In the first combustor (), syngas is burned using the compressed air, and the resultant hot gases are expanded in the first turbine (). In the second combustor, syngas is burned using the gases coming from the first turbine () and the resultant gases are expanded in the second turbine () such that the nitrogen that occurs in the separation of the air is led to the gas turbine () to be compressed.
