摘要
对太原嘉节燃气热电公司汽轮发电机组抽真空系统进行优化节能改造,解决了机组在夏季工况下机组真空偏低和真空泵叶轮汽蚀严重的问题,改造后提高了机组真空,大幅降低了真空泵的检修维护成本,起到了很好的节能效果。对蒸汽喷射器在电厂机组抽真空系统节能优化中的应用进行了研究。
The energy-saving optimization of turbo generator unit vacuum-pumping system of Taiyuan Jiajie Gas-fired Thermal Power Company can solve the problems of low vacuum of the unit and serious cavitation of the impeller of the vacuum pump in summer.After modification,the vacuum of the unit was increased,the maintenance cost of the vacuum pump was reduced greatly,and the energy-saving effect was very good.This paper studied the application of steam ejector in energy-saving optimization of vacuum-pumping system of power plant units.
