| 摘 要： | 以装机容量为12MW的某背压式供热机组为例,分冬季和夏季两种工况对小型蒸汽热电联产系统各部分的热效率以及各设备的性能参数进行了分析,得出了热负荷变化对热电联产热效率的影响关系,提出在全年热负荷变化较大的情况下,小型热电机组热效率不高,系统全年节能效果不理想。

| Abstract: | Took a heat-supplying plant(12MW)as an example to analyze and calculate small units of co-generation of heat and power in winner and summer,and got the thermal efficiencies and capability parameters of each part of the system.Through the comparison of the calculation results of each month condition of whole year,the article presents the relation between the efficiency of CHP unit and the variation of thermal load. |
