Title:
COMBINED POWER PLANT
Document Type and Number:
WIPO Patent Application WO/2019/198756
Kind Code:
A1
Abstract:
The purpose of the present invention is to allow a heat exchanger provided in a boiler to be easily positioned at a desired position. This combined power plant (1) is provided with: a gas turbine (11); a first exhaust heat recovery boiler (24) having an ultrahigh-pressure superheater (31) that heats steam by using the heat of exhaust gas from the gas turbine (11); an ultrahigh-pressure steam turbine (51) that is driven by the steam heated by the first exhaust heat recovery boiler (24); a third ultrahigh-pressure steam pipe (38) that guides the steam heated by the first exhaust heat recovery boiler (24) to the ultrahigh-pressure steam turbine (51); a second exhaust heat recovery boiler (25) having a high-pressure reheater (34) that heats the steam discharged from the ultrahigh-pressure steam turbine (51) by using the heat of the exhaust gas from the gas turbine (11); a high-pressure steam turbine (52) driven by the steam heated by the second exhaust heat recovery boiler (25); and a second high-pressure steam pipe (67) that guides the steam heated by the second exhaust heat recovery boiler (25) to the high-pressure steam turbine (52).
