摘　　要：针对部分地区小型热电联产系统运行不合理、冷源损失大、节能效果不理想的问题,通过对某小型热电联产系统全年运行状况的调查,计算了热电机组的发电效率、热效率及汽机冷源能量损失,分析了小型热电联产系统能耗大的主要原因,提出了提高热电联产系统能源利用效率、改进热电联产集中供热形式的措施,为热电联产系统改造和扩建工作提供参考。In some areas,the operation scheme of small-scale units of cogeneration of heat and power is unreasonable and thermal loss of condenser is serious.One small-scale cogeneration system was investigated and generating efficiency,thermal efficiency and thermal loss ratio of condenser were analyzed to fix the main factors of system energy loss,and several measures which can be used to improve the system significance were presented in this paper to increase the energy efficiency and to improve the operation modes of central heat supply of small-scale units of cogeneration of heat and power.
