火电厂补水方式的选择探讨

Choice of the Way of Water Filling

主要论述以深度除盐水作为补充水的火电厂改变补水方式所带来的双重经济效益:其一是将补充水入口从除氧器改为凝汽器,提高了回热经济性;其二采用补充水进入凝汽器的方式来达到利用排汽的余热,适当减少冷源损失的目的,改善凝汽器的真空。提出了较合理的补水方式,为老电厂改造,及新电厂的修建提供了节能性的建议.

This paper discusses in depth saline water in a supplementary thermal changes brought by way of filling double economic benefit： One is to supplement the added water inlet from condenser instead of from deaerator, improves the heat efficiency. By entering the water supplement condenser way to achieve the exhaust steam heat utilization, reduce the loss of cold source, improves the vacuum condenser. The paper puts forward a reasonable way to add water old plant, for the old and the new power plant, the energy conservation of the building provides advice.
