ABSTRACT:
A method for operating a gas-turbine and steam-turbine plant and a plant working according to the method, utilize exhaust gas from a gas turbine for steam generation when the plant is in operation. In order to ensure that a gas-turbine model can be freely selected, irrespective of its power rating and with a reduction in exhaust gas losses, in the case of both a new plant and a retrofitting of an already existing plant, a first part stream of exhaust gas from the gas turbine is used as combustion air for the combustion of a fossil fuel and a second part stream of exhaust gas from the gas turbine is utilized for waste-heat steam generation. At the same time, for steam generation, a combination of a fossil-fired steam generator and a waste-heat steam generator is located downstream of the gas turbine on the exhaust gas side, in each case through a part-stream conduit. The steam generation by the combustion of the fossil fuel and the waste-heat steam generation take place in a common water/steam circuit of the steam turbine.
