吸收式热泵回收热电厂余热的经济分析

Economic Analysis for Absorption Heat Pump Recycling the Waste Heat in Thermal power Station

热电厂汽轮机的排汽中含有大量热能,采用吸收式热泵可以对其回收,并可以利用该热能来加热热网水,提高热电厂的供热能力,还可以减少冷水塔的汽水损失,减少燃煤消耗量和污染物的排放量。通过分析计算可知,供热机组采用吸收式热泵进行改造后,可以有效的提高机组的能源利用率和效率,同时电厂的经济效益也有明显的提高。

Steam turbine exhausted steam discharges a large amount waste heat into the atmosphere in thermal power station. The absorption heat pump can recover the waste heat and heat the heating net water,increase the capacity of heat supply,reduce water consumption in cooling tower,and reduce coal consumption as well as emission pollution.After reformed with absorption heat pump,the unit ＇s thermal efficiency and exergy efficiency increase effectively through analysis and calculation,in the same time the economic efficiency increase significantly.
