１は蒸気タービン排汽を凝纏する復水器でおる。The gas turbine, steam turbine, and power generation 11' are directly connected to one shaft, and the configuration is simple as a 9L shaft type combined 7 runt, but due to the maximum output that can be produced by the gas turbine,
The overall output of one shaft will be reduced, and the installation of multiple shafts will be uneconomical if the size of the shaft is large. The present invention is a uniaxial type +1
The boiler, steam turbine, and power generation are all shared as the basic gas turbine unit, and economic efficiency is achieved by using only two gas turbines, which have a limited size. -Second
The figure shows one folding process of the present invention. 1 is the IQ gas turbine compressor, 2 is its combustor, 3 is its fuel pipe, 4 is its gas turbine, and 5 is its exhaust gas duct. 6 is an exhaust heat recovery boiler, 7 is a chimney, 8 is a steam drum, 9 RJ steam pipe, 10 is a steam turbine directly connected to the shaft of the gas turbine 4, and 12 is a generator directly connected to the same shaft. 1

の問題点がある。Exhaust gas duct 1 of gas turbine according to point of view H@2 of the present invention
The generated steam is guided to a common exhaust heat recovery boiler with the first gas turbine, and the generated steam is guided to a steam turbine directly connected to the first gas turbine shaft, thereby eliminating the need to install a dedicated boiler and steam turbine for the second gas turbine. It is at the point where it can obtain twice the output t- of the combined shaft directly connected to the gas turbine 1.
The point is that it is possible to construct a combined plant that is more economical than the conventional type. If the second gas turbine [is directly connected to the first gas turbine shaft, the second generator is not required,
Historically, although it is an economical configuration, current gas turbines have problems in that torque cannot be transmitted through the compressor shaft, and gas turbine pipes must be manufactured to rotate in opposite directions.
