Abstract
In a method for operating a gas turbine () in a combined cycle power plant (), air is drawn in and compressed though the gas turbine (), the compressed air is led to a combustor () to burn a syngas recovered from a fossil fuel, especially coal, and the gases that result in the course of the combustion are expanded in a downstream turbine (). In such a method, 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 (); in the first combustor (), syngas is burned with the compressed air, and the resultant hot gases, e.g., flue gases, are expanded in the first turbine (), and in the second combustor syngas is burned by the gases coming from the first turbine (), and the resultant hot gases are expanded in the second turbine ().
