火力发电厂的冷端损失一直是困扰研究人员的一大问题，而优化冷端系统对提高凝汽器运行性能，实现电厂节能降耗起着十分重要的意义。汽轮机排汽损失对于低品位的采暖用热而言则是很好的“宝贝”，乏汽供热改造为这部分能量的利用提供了一种有效的方式，但改造后会对系统产生诸多影响。对此，着重阐述了乏汽供热改造对空冷系统真空及防冻的影响。

The loss of the cold end of the thermal power plant has been a big problem puzzling the researchers, and optimization of cold end system to improve the operation performance of the condenser to achieve power saving and consumption plays a very important significance. Steam turbine exhaust steam loss for heating of low grade heat used is very good “baby”, lack of steam heating transformation provides an effective way for the utilization of this part of the energy, but after the transformation will impact on many systems. This paper mainly expounds the influence of the air cooling system vacuum and antifreeze by the heat supply and cooling system.
