文章致力于膜式除氧器的改造、传热计算、设计,以及运行调节方面的应用研究。文章在详细介绍了膜式除氧器的改造方法后,着重论述了采用蒸汽在竖管壁膜状凝结的理论,进行该除氧器的传热计算;并认为:合理布置旋流管,以及正确选择一级除氧结构的空间高度,是膜式除氧器的设计关键.文章最后对此除氧器的除氧性能,以及运行调节的特点也作了探讨. The article devotes to the membrane deaerator transformation, the heat transfer computation, the design, as well as the movement adjustment aspect application research. After introducing the modification method of the membrane deaerator in detail, the article focuses on the theory of using the steam to condense in the membrane wall of the standpipe and carries out the heat transfer calculation of the deaerator. It is also considered that the reasonable arrangement of the cyclone and Correctly choosing the spatial height of a deaeration structure is the key to the design of the membrane deaerator.At last, the deaeration performance of the deaerator and the characteristics of operation regulation are also discussed.
