The influences of water sub-cooling on water discharge behaviors in the water storage tank have been studied experimentally with a test rig,having windows for visualization.From this study,it founds that the gravitational discharging course is effected strongly by the steam condensation,token place between steam and cold water in the tank during discharging.Larger is sub-cooling of the water,stronger is the heat exchange in condensation of steam and deeper is the steam penetrated into water.The critical steam...

The influences of water sub-cooling on water discharge behaviors in the water storage tank have been studied experimentally with a test rig,having windows for visualization.From this study,it founds that the gravitational discharging course is effected strongly by the steam condensation,token place between steam and cold water in the tank during discharging.Larger is sub-cooling of the water,stronger is the heat exchange in condensation of steam and deeper is the steam penetrated into water.The critical steam flow may be achieved in the narrow section of the pressure balance piping,which limits the steam supply and then forms a lower discharge flow period.The result indicates also that the pressure of steam source has influence on the steam column in water and discharge flow in the later discharge phase.

用可视实验装置研究了流体欠热度对容器排放特性的影响。研究发现:蒸汽与排放容器中的冷流体作用形成的蒸汽冷凝特性极大地影响了容器中流体的排放过程。欠热度愈大,蒸汽冷凝换热过程愈强,蒸汽汽柱入水深度愈深,因此蒸汽可能在压力平衡管中达到临界流速,从而产生蒸汽供应限制,形成小排放流量阶段;系统(汽源)压力对后期排放流量和蒸汽汽柱入水深度也有一定影响。

Taking 600 MW directly air cooled units as an example,a mathematical system model of directly air cooled units under variable operating conditions has been elaborated,considering pressure and heat dissipation loss of the exhaust pipe,as well as the pressure difference between burbine exhaust and condenser entrance,caused by the steam column concerned.Characteristic curves of directly cooled units' cold end system were then program calculated and the effects on the set's characteristics,caused by varying...

Taking 600 MW directly air cooled units as an example,a mathematical system model of directly air cooled units under variable operating conditions has been elaborated,considering pressure and heat dissipation loss of the exhaust pipe,as well as the pressure difference between burbine exhaust and condenser entrance,caused by the steam column concerned.Characteristic curves of directly cooled units' cold end system were then program calculated and the effects on the set's characteristics,caused by varying condenser pressure,as well as exhaust pipings pressure loss,were analyzed,which may all serve as a reference for operating air cooled units economically.Figs 7,tables 2 and refs 7.

以600 MW直接空冷机组为例,考虑排汽管道的压损,排汽口和凝汽器入口间水蒸汽柱高度压差及排汽管对环境散热量,建立了直接空冷机组冷端系统变工况数学模型,编程计算并作出直接空冷机组冷端系统特性曲线,分析了空冷凝汽器压力及管道压损变化时的机组特性,对于空冷机组的经济运行具有一定的指导价值。图7表2参7
