The object of the invention is a combined-cycle power plant that can be used at heat electric power plants. The combined-cycle power plant includes a gas turbine plant, steam recovery boiler connected to it by gas section with transition gas duct, this has two or more vapor-water circuits of different pressure stages, steam turbine plant connected with pipelines to the vapor-water circuits of the recovery boiler, condenser, condensate pump, feeding pump, deaerator, discharge gas duct, flue, connecting pipelines. The steam turbine plant includes one pressure steam turbine. The vapor-water section of the lower pressure stage of the recovery boiler is connected to neighboring vapor-water section of the higher pressure stage by means of ejector. Technical result is in decrease of overall dimensions of the combined-cycle power plant, increase of its reliability. |
