空冷凝汽器迎面风速优选分析

Preferred Face Velocity Aalsis of Air Coled Condener

空冷凝汽器是一种以空气作为冷却介质,将汽轮机排汽这一被冷却介质冷凝成凝结水的换热设备。在设计空冷凝汽器时,迎面风速的选取直接影响了其设备成本以及运行成本,这两块成本合称为综合成本。提出了一种以综合成本最低为目标的空冷凝汽器迎面风速的求取方法,此时的迎面风速为优选风速,从而得出的最优的设计方案。

Air cooled condenser is a kind of heat exchange equipment,which uses air as the cooling medium to directly cool the exhaust steam of steam turbine into condensed water.When designing the air cooled condenser,the selection of the face velocity directly affects the facility cost and the operation cost,which are collectively called the comprehensive cost,This paper present an preferred method of ait cooled condenser's face velocity aiming at the lowest comprehensive cost,the optimal design scheme is obtained.
