对燃气轮机进口处的空气进行预冷，能够提高发电机组的输出功率。与蓄冷方法相比，使用燃气轮机－蒸汽联合循环电站余热锅炉低压蒸发器的一部分蒸汽为热源，利用溴化锂吸收式制冷机制取冷源，冷却燃气轮机进口处的空气，以提高发电机组的输出功率。该方法技术可行，经济效益显著。图４表２参７
Pre-cooling the air at the gas turbine inlet increases the output power of the generator set. Compared with thermal storage method, a part of steam of low pressure evaporator of waste heat boiler of gas turbine-steam combined cycle power plant is used as heat source, and lithium bromide absorption refrigeration machine is used to make cold source to cool the air at gas turbine inlet to increase the output power of generator set. The method is feasible and has obvious economic benefits. Figure 4 Table 2 Reference 7
