摘要
汽轮发电机组射水抽气器工作水温度直接影响抽气器工作性能,通过对射水系统进行改造,利用系统现有低温介质冷却工作水,可以让射水系统以不溢流的方式运行,在保证汽机真空同时对能源介质和能量进行回收,提高系发电系统运行的热效率。
The working water temperature of the water jet air ejector of steam turbine power generator has direct effect on the work performance of the ejector. Through modification of the water ejector system, using existing low-temperature medium to cool working water can allow the ejector system operating without overflowing, to ensure vacuum of the steam turbine while recover energy media and improve the thermal efficiency of the generator system operation.
