分析在小型热电站热电联产中的应用

Application of Exergy Analysis in Heat and Electricity Combination of Mini-type Thermal Power Plant

用■平衡分析法分别对小型热电联产系统和分散锅炉供热系统进行了■流分析，两者 的■效率对比表明，用热电联产系统取代分散锅炉供热是节能措施之一。通过对热电联产系统内各环节的■流损失计算，得出各热力设备的■效率，可找出系统用能不合理的主要薄弱环节，为今 后设备工艺改进指出方向。

This paper adopts exergy balance analysis method to respectively analyze exergy flow of mini-type heat am electricity combination system and single boiler house providing heat system. By comparing both exergy efficiency derived above,it points that heat and electricity combination system is a kind of energy saving method replacing single boiler house providing heat system. And it also calculates exergy loss of each portion in this system, further obtains exergy efficiency of all thermodynamic equipments and puts foward main irrational portion of system and correct direction of equipments improvements in the future.
