摘要
用小型工业汽轮机驱动给水泵以及供热系统循环泵可以减少节流阀的压力损失,汽轮机排汽用于除氧器加热,提高热电厂的经济性。采用变频调速器,系统调节的操作效率更高、响应时间更短。改造方案有利于热电厂的能量转换和提高电厂的经济性。
A small industry turbin drive a feed-water pump unit and heating system cycle pump can be much more economically incorporated into thermal plant, such as reducing pressure of butterfly throttle and waste vapor were full used by oxygen extractor. Utilizing speed adjusting function of the frequency converter, the system has high operation efficiency and less time to adjustability. The reform project is a good manner of thermal plant energy conservation and increase the economy of power plant.
