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