摘要： A combined cycle plant includes a heat exchanger (3) for recovering heat into compressed air or gas turbine fuel to be supplied into gas turbine (01). The plant is arranged such that steam is used as high temperature side working medium of the heat exchanger (3). 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 (02), so that gas turbine efficiency and combined efficiency can be enhanced and plant manufacturing cost is reduced.

摘要： A combined cycle power plant includes a combination of a gas turbine plant and steam turbine plant. The gas turbine cooling steam temperature is adjusted appropriately so that the gas turbine can be made of easily obtainable material. Steam supplied from the intermediate pressure evaporator is mixed into the cooling steam supply passage for supplying therethrough exhaust steam from the high pressure steam turbine into the gas turbine high temperature portion as cooling steam. Thus, cooling steam temperature is lowered without lowering of the entire efficiency, and material of less heat resistant ability becomes usable as material forming the gas turbine high temperature portion to be cooled. Thus, design and manufacture of the gas turbine may be satisfied by less expensive and easily obtainable material.

摘要： An exhaust system for a marine gas turbine may suppress a reduction of an efficiency even if a space therefor is small. In the exhaust system for a marine gas turbine, in which an end portion of an exhaust diffuser 2 is assembled into an exhaust chamber 1 connected with an upper exhaust eductor 4, the end portion of the exhaust diffuser 2 is disposed in the vicinity of an inlet of the exhaust chamber 1. An outlet 2a of the exhaust diffuser is slanted so that an upper portion of the outlet of an end of the exhaust diffuser is located upstream of a lower portion of the outlet. As a result, the exhaust gas may readily flow around and into the exhaust eductor 4.
