摘要: 对某发电公司2台670MW机组循环水系统由单元制运行改为扩大单元制运行进行了研究和试验,通过热力试验找出了使凝汽器运行在最佳背压下的循环水泵切换工况点,达到了经济、节能的目的。

关键词: 扩大单元制, 最佳背压, 切换工况点, 最佳运行方式

Abstract: In a power generation company, some researches and tests were carried out for changing the operation mode of the circulating water system of two 670MW units over from the unit system to the expanded unit system. Based on the thermodynamic test, the switching operating point which can make the condenser to operate in best back pressure was found. So the goal of economy and energy conservation was achieved. 

Key words: expanded unit system, best back pressure, switching operating point, optimal operation mode
