摘要

基于火积耗散理论

对凝汽器主凝结区内的换热过程进行计算分析。结果表明:影响凝汽器内火积耗散率的主要因素为冷却水入口温度、冷却水流量、空汽含量、凝汽器压力、管束布置等;沿冷却水流动方向火积耗散率不断减小

减小速度随冷却水温的提高而减小;不同冷却水入口温度下的火积耗散率沿流程变化趋势一致;在5~20℃之间火积耗散率随冷却水入口温度的增加而迅速减小

高于20℃冷却水入口温度对火积耗散率无影响。

Abstract

On the basis of entransy dissipation theory

the heat transfer in main condensing zone of a condenser was analyzed

and calculation method of the entransy dissipation rate was developed.The results show that

major factors affecting entransy dissipation rate of the condenser were the cooling water inlet temperature

cooling water flow rate

air vapor content

pressure in the condenser and tube bundle arrangement.Along the cooing water flow direction

the entransy dissipation rate decreased gradually

and the reduction rate dropped with an increase in cooling water temperature.The variations of entransy dissipation rate along the flow direction varied little at different cooling water inlet temperatures.At temperatures between 5℃and 20℃

the entransy dissipation rate reduced sharply with an increase in the cooling water inlet temperature.Cooling water inlet temperatures higher than 20℃had no influence on the entransy dissipation rate.
