Gas turbine exhaust heat recovery plant

摘要

PROBLEM TO BE SOLVED: To provide a gas turbine exhaust heat recovery plant capable of suppressing thermal stress due to sudden output fluctuation and reducing a life consumption rate. A gas turbine exhaust heat recovery plant 500F includes a plurality of gas turbine exhaust heat recovery devices including a gas turbine 10B and an exhaust heat recovery boiler 20 that recovers the exhaust heat of the gas turbine 10B to generate steam. , A part or generation of water heated by at least one gas turbine exhaust heat recovery device among the steam utilization facility 503 that utilizes the steam generated by the exhaust heat recovery boiler 20 and the plurality of gas turbine exhaust heat recovery devices. It is provided with an inter-device heat medium supply unit 504F capable of supplying a part of the generated steam to another gas turbine exhaust heat recovery device. [Selection diagram] FIG. 12
