凝汽器传热与节能分析

The analyze of heat transfer and energy-saving of condenser

真空是影响汽轮机带负荷和热效率的一个重要经济指数,传热效能又直接影响真空的运行高低,从传热学的角度分析,结合唐山开滦热电有限责任公司林西电厂凝汽器运行情况,提出从该厂凝汽器传热效能,改善交换工况,提升凝汽器真空的方法。

Vacuum is an important economic index number influencing steam turbine＇s load and thermal efficiency. Heat transfer potency directly influences the level of vacuum. In this paper, we analyzed it from the view of heat transfer, and associated with the running conditions of the Linxi power plant of Kailuan heat and power plant Co. Ltd., also put forward some methods such as increasing thermal transfer efficiency, improving the work condition of heat exchange, and raising the level of the oondenser＇s vacuum.
