Combined cycle plant

摘要

A combined cycle plant that combines a conventional thermal power plant and a gas turbine plant, comprises a dump system 1 that connects a main steam pipe 60 with the condenser 25 and dumps the steam generated by the boiler 10 into the condenser 25, bypassing the steam turbine 40. An HRSG HP turbine bypass system 2 and an HRSG LP turbine bypass system 3 connect the HP pipe 70 and, respectively, LP pipe 71 of the heat recovery steam generator 50.
