The gas turbine O in the figure is configured as a system having no bypass stack. The steam turbine 1 is a turbine (a low-pressure turbine) installed in a power plant or the like, and is configured to be driven by steam to rotate a generator (not shown) to generate power. For this reason, a boiler 2 for generating steam having a predetermined pressure and temperature is installed on the upstream side of the steam turbine 1, and a water supply system for condensing turbine exhaust and condensing water on the downstream side of the steam turbine 1 as condensate water. , An air-cooled condenser 3 is provided. In a conventional plant that involves normal combustion, the steam generated by the boiler is converted to electric output by a steam turbine, or the extracted steam is sent to the factory from the boiler or the extraction of the turbine.In this case, in particular, the turbine is stopped and the boiler is stopped. There is not much need to drive alone. When an attempt is made to isolate the turbine with a normal condenser, a bleed pipe, a low-pressure heater or a BFP-T
(Turbine for boiler feed pump) Exhaust pipes and the like are congested, making isolation difficult.
