摘　　要：以某区域供冷供热项目为例,分析对比某700 MW电厂利用低品位循环水余热供能、利用高品位蒸汽供能,以及同时利用高低品位热源供能的3种方案。结果表明:利用低品位循环水余热供能经济性最好。该方案可为电厂实现能源阶梯利用提供参考。Taking a regional cooling and heating project as an example,following three schemes with using the heat source from a 700 MW power plant for energy supply were analyzed and compared,such as using the waste heat of the low grade circulating water,using the high grade steam,and using the both of the high and the low grade source.Results show that,when using the waste heat of the low grade circulating water for energy supply,the optimal economy can be obtained.This may serve as a reference for the realization of the stepped utilization of energy in power plants.
