燃机联合循环机组直接空冷凝气器选型优化

ACC design optimization for gas turbine combined cycle units

根据传热学基本原理,建立空冷器初始温差(ITD)和迎面风速对直接空冷凝汽器(ACC)换热面积和耗电量的影响的数学模型。以某F级一拖一联合循环项目直接空冷机组为例,计算不同的ITD和迎面风速对于电厂净出力和空冷凝汽器换热面积的影响,从而获得最佳的空冷凝汽器选型参数。

According to the basic principles of heat transferring,it creates a mathematical model of heat transferring area and power consumption of ACC affected by initial temperature difference(ITD) and head wind velocity. Taking an F-class oneplus-one CCPP as an example,it calculates the influence of ITD and head wind velocity on net output and ACC heat transferring area of power plant and obtains the optimized ACC design parameters.
