摘　　要：对600 MW空冷机组提出在空冷装置和排汽装置分别控制压力,通过在排汽装置抽真空管道上加装调节阀进行,优化了机组的真空,提供经济性。并且,在空冷装置至排汽装置凝结水回水垂直下降管道上安装连续排汽系统,防止垂直下降管因汽气混合造成剧烈振动,有利于机组的安全稳定运行。It puts forward suggest that control the pressure of air cooler and exhaust equipment respectively. To realize the suggestion, it fixes the regulating valve in the vacuum pipe of exhaust equipment. So the vacuum of the unit is optimized and the economy is improved. Furthermore, continuous air exhaust system is assembled in the vertical downcomer from the air cooler to the exhaust equipment. It can prevent strenuously vibrating for mixed air. And this is favorable to the operation stability of the unit.
