Abstract
A combined cycle plant includes a heat exchanger (,) for recovering heat into compressed air or gas turbine fuel to be supplied into gas turbine (,). The plant is arranged such that steam is used as high temperature side working medium of the heat exchanger (,). Thus, the heating medium supply passage can be made of ordinary steam piping and piping cost is reduced. Also, gas turbine exhaust gas is led directly into a waste heat recovery boiler (,), so that gas turbine efficiency and combined efficiency can be enhanced and plant manufacturing cost is reduced.
