摘要
本文通过分析国内已经投产和订货的1000MW超超临界机组给水泵的配置情况,对同容量、参数的空冷机组给水泵目前的主流配置和未来发展趋势给出意见;在充分考虑空冷系统防冻要求的前提下,对直接和间接空冷机组取消启动电泵的可能性进行了探讨。
Through the analysis of the situation of the configuration for the operated and ordered feed water pumps of 1000MW Ultra-supercritical units,this paper provides the suggestion of the mainstream of the current configuration and the future development trend for the same capacity and parameters of the feed water pump used for air-cooled unit.By sufficient consideration of the requirements of preventing frostbite for air-cooling system, the possibility to cancel the electric start-up pump for the direct and indirect air-cooled units is also discussed.
