EXHAUST HEAT RECOVERY BOILER FOR COMBINED CYCLE POWER PLANT

摘要

PROBLEM TO BE SOLVED: To provide a high efficiency exhaust heat recovery boiler for a combined cycle power plant.;SOLUTION: The combined cycle power plant 2 includes a steam turbo machine system 6 including at least one steam turbine 40, 50, 64 extracting power from gas at second temperature. The combined cycle power plant 2 includes the exhaust heat recovery boiler 90 including a main housing 94 connected to a gas turbine 9 via fluid. The exhaust heat recovery boiler 90 includes a plurality of heat pipes 110, 115, and extends in the main housing 94 connected to gas at first temperature via fluid. The plurality of heat pipes 110, 115 are also connected to the gas at second temperature via fluid. Heat is absorbed from the gas at first temperature by the plurality of heat pipes 110, 115, and gas at third temperature is formed by delivering the heat to the gas at second temperature.;COPYRIGHT: (C)2010,JPO&INPIT
