300MW直接空冷机组乏汽余热利用改造方案研究

介绍了高背压供热和吸收式热泵两种火力发电厂余热利用技术,通过对三种余热利用方案的对比,确定了适合直接空冷机组的余热利用改造方案。叙述了具体的改造方案,并进行了经济性分析,在得出结论的基础上,提出了应该注意的事项,以期为其他电厂进行类似改造提供借鉴。

This paper introduces two kinds of waste heat utilization technology for thermal power plant, high back pressure heating and absorption heat pump. Based on three kinds of waste heat utilization scheme comparison, the waste heat of direct air cooling unit for the reconstruction scheme is selected, the transform scheme is described in detail, and an economic analysis is given. Finally, draws the conclusion, and puts forward some matters should pay attention to, to provide a reference for the other similar transformation of power plant.
