摘要
构建了4种典型工程条件下采用吸收式热泵回收发电机组循环水余热的收益估算模型,并以某300MW机组的循环水余热利用项目为例进行计算。结果表明,不同估算模型之间的收益结果最小为1 262万元,最大为4 100万元,差别较大。因此,应根据工程具体情况选择适当的收益估算模型进行计算。收益估算方法为吸收式热泵回收发电机组循环水余热应用于城市供热工程提供了依据,具有较高的应用价值。
Earning estimation models for waste heat recovery of circulating water by absorption type heat pump under 4 typical engineering conditions were derived.Taking the waste heat utilization project of recycled water in a 300 MW unit as the example,benefit calculation was performed.Results show that,among the earnings obtained by different estimation models,the minimum value is 1.262×107 yuan while the maximum is 4.100×107 yuan,which has big difference.Therefore,the authors suggest that proper earning estimation model should be selected according to specific conditions when carrying out the calculation.The earning estimation method provides the basis for using absorption type heat pump technology to recover waste heat of circulating water for city heat supply engineering.
