The deaerator shall be capable of satisfactory operation under normal operation, condition of turbine trip and HP-LP bypass operation ( full open) and lowest condenser pressure. 在正常情况、透平跳机、高低压旁路运行(全开)情况、最低冷凝压力下,除氧器都能良好运行。
While for major auxiliaries, deaerator, feedwater tank, feedwater pump, turbine bypass, condenser, condenser air extractor are all different from the small thermal power units. 对于主要辅机,除氧器、给水箱、给水泵、汽机旁路、凝汽器、凝汽器抽气器均与小火电机组不同。
Aiming at less economical of dual-pressure condenser under winter condition, two plans were proposed: switch to single pressure condenser operation by changing the circulating water line and bypass water circulation of low pressure condenser to improve the thermal efficiency. 并对冬季工况双压凝汽器经济性较差的问题,提出通过改变循环水管路切换至单压凝汽器运行和旁通低压侧循环水量以达到提高机组经济性的两种技术方案。
