低位热能回收系统对汽轮机运行的影响分析

Effect of Low-Heat Energy Recovery System on Steam Turbine Operation

利用热量平衡和质量守衡的原理对凝结水作为工作介质的低位热能回收系统中参数进行理论计算和分析,找到了影响原因。最后提出改进建议,实践证明利用二级除盐水作为工作介质虽不能全部回收乏汽,但回收的热量要比利用凝结水作为工作介质时多。

When condensed water was used as working medium in the low heat energy recovery system, the main operating parameters of steam turbine would change. Theoretical calculation and analysis were performed based on the theory of heat balance and mass bal-ance and the cause of the problem was found out. Finally improvement proposal was provid-ed. Practice has shown that though using demineralized water as working medium cannot fully recover exhaust steam, it recovers more heat then using condensed water as working media.
