摘要
根据传热学基本原理,通过迭代计算得到换热系数K,进而得到换热面积的数学模型。同时以某600MW直接空冷机组为例,计算其设计工况下的换热面积。并充分考虑各种影响因素,得到其换热面积变化曲线,为直接空冷凝汽器换热面积的设计计算提供参考依据。
According to the basic principles of heat transfer, and through iterative computation, get the heat transfer coefficient K, and the mathematical model of heat transfer area. Take the 600MW direct air cooling unit for example; calculate the heat transfer area under the design condition. And fully consider each kind of influencing factor,to obtain the change curve of heat transfer area, provide reference information for the design calculations of condenser heat transfer area of direct air cooling unit.
