摘要： In a combined cycle power plant, exhaust from a high pressure turbine is branched so that part of it is supplied to a steam cooling system, and the other part of it is supplied to an inlet of a reheater of an exhaust heat recovery boiler. The exhaust supplied to the steam cooling system performs predetermined cooling and becomes heated. Then, the heated exhaust is guided from an outlet of the steam cooling system to an intermediate position of the reheater, merged with the exhaust supplied to the inlet of the reheater, and temperature-adjusted in the reheater. Then, the reheated, combined steam is supplied to a downstream turbine for heat recovery. Thus, a safe, reliable steam cooling system is achieved by effectively using a sufficient amount of high pressure turbine exhaust.

摘要： In a combined cycle power generation plant in which a gas turbine is cooled by steam, pressure loss of the cooling steam is prevented from increasing and the cooling steam is recovered efficiently. The gas turbine's stationary blade or moving blade is provided with a plurality of mutually independent passages which are arranged in parallel, whereby pressure loss of the cooling steam can be reduced.

摘要： A combined cycle power generation plant comprises a waste heat recovery boiler (20) having a stabilizing burner (25) at an upstream position thereof The stabilizing burner is ignited during the time of start-up and speed increase of a gas turbine (11) so that steam generation at the waste heat recovery boiler is accelerated. The steam is used effectively for cooling the gas turbine, driving a steam turbine, and for gland steam. In addition, exhaust steam from the steam turbine is also used to cool the gas turbine. Consequently, the time for the plant to reach a full load can be shortened.

摘要： A combined cycle power plant is disclosed, whose target high-temperature portion in the gas turbine can be reliably and sufficiently cooled, and in which the heat generated via the cooling can be reliably recovered, thereby improving the efficiency. Here, the exhaust gas from the high-pressure turbine is introduced as cool steam to the steam cooling system for cooling the target high-temperature portion in the gas turbine. This cooling process is efficiently and suitably performed by using the characteristic of the above high-pressure exhaust gas relating to quantity, pressure, or temperature.
