改变补水方式的节能效益解析

主要论述以深度除盐水作为补充水的中小型火电厂，尤其是热电厂改变补水方式所带来的双重经济效益；补充水进入凝汽器可利用排汽余热，适当减少冷源损失；将补充水入口从除氧器改为凝汽器，可提高回热经济性。

An Analysis of the Economic Benefits Derived from Energy-saving through a Change in a Make-up Water Supply Mode

This paper discusses the economic benefits enjoyed by small and medium sized thermal power plants using extra pure demineralized water. Specially noted are the dual economic benefits realized by cogeneration power plants through a change in a make up water supply mode. In this case when the make up water is fed into a condenser the exhaust steam waste heat can be utilized, resulting in a reduction of the cold source loss. Moreover, heat regeneration economy may be enhanced when the make up water inlet is relocated from a deaerator to the condenser.
