大气式热力除氧器低位布置

Arrangement of Low Position of Atmospheric Thermal Deaerator

分析了大气式热力除氧器的除氧原理,以及除氧给水汽蚀的原因,论述了通过降低除氧给水温度或提高压力来降低除氧器布置高度、避免水泵汽蚀的措施,通过对工程实例的分析,说明了选择水水换热器、设置喷射泵需要注意的问题。

The paper analyzes the deaeration principle of the atmospheric thermal deaerator, and the reason of deaeration, water supply and cavitation, discusses the measures of reducing height of deaerator and preventing water pump cavitation by reducing the temperature of deaeration and water supply or increasing the pressure, by analyzing the engineering examples, the paper described the problems of selection of water-water heat exchanger and arrangement of injection pump that need to be concerned.
