Technical Field

Background
At present, the initial temperature of the gas turbine for ground power generation is in the range of 1400-1700 ℃, and the initial temperature of the gas turbine for aviation is as high as about 2000 ℃, which is far greater than the melting temperature of metal materials. In order to ensure the safety of the combustion engine, two protection measures of cooling and heat insulation are generally adopted. The air cooling method is that part of compressed air is led out from the last stage of the compressor and used as Turbine Cooling Air (TCA), the air flows through high-temperature parts such as a combustion chamber, a blade, a wheel disc chamber and the like through different paths, partial heat is taken away or an air film heat insulation layer (thermal barrier) is formed, and the temperature of metal is controlled below the melting temperature of the metal material. Because the temperature of the compressed air of the part led out from the compressor is higher, the compressed air needs to be cooled and then led to the cooling channel, and the cooling water of the TCA comes from the outlet of the high-pressure water supply pump. The typical design is that a TCA cooler is connected with a high-temperature economizer water supply loop of a waste heat boiler in parallel, and a single-suction single-outlet high-pressure water supply pump provides circulating power. The disadvantage of this typical design is that the high pressure feed pump is too energy intensive due to the pressure-limited TCA cooler water side pressure, especially at low loads, because to prevent flashing of the TCA cooler outlet water in the piping, the pressure must be maintained above the saturation pressure corresponding to the outlet water temperature, which is much higher than the pressure required for the feed water.
