逆流式双曲线自然通风冷却塔设计浅谈

Discussion on Design of Counterflow Hyperbolic Natural Draft Cooling Tower

冷却塔作为电厂冷端系统的主要设备之一,其冷却能力特性直接关系到电厂运行的安全性和经济性。目前大部分设计单位对于逆流式双曲线自然通风冷却塔的设计计算仍采用《工业循环水冷却设计规范》中的焓差法,简便的一维算法因能满足大部分工程设计精度而得到广泛应用。

Asoneof themainequipment ofcoldend system,the cooling capacityof coolingtower isdirectlyrelated to the safetyand economy of power plant operation.At present,most design units still use the enthalpy differencemethodwhich is presented in the"Design Code of Industrial Circulating Cooling Water"to calculate and design the counterflow hyperbolic natural draft cooling tower,and the simple one-dimensional algorithm can be widely applied to meet the accuracy of most engineering design.
