冷却水流程数对凝汽器热力性能的影响
The Impact of the Number of Cooling-water Passes on the Thermodynamic Performance of a Steam Condenser
【摘要】 电站凝汽器可以设计成冷却水双流程和单流程。利用自行开发的凝汽器工作特性数值模拟软件PPOC3 0模拟和分析了冷却水流程数对电站凝汽器的热力性能的影响 ,结果表明单流程凝汽器比双流程凝汽器有更高的热负荷和更小的汽侧阻力。
【Abstract】 Power plant steam condensers can be designed as single-pass or two-pass ones. By using a self-developed computer program PPOC3.0, a software for the numerical simulation of condenser operation characteristics, the authors have simulated and analyzed the impact of the number of cooling water passes on the thermodynamic performance of power-plant steam condensers. The results of simulation and analysis indicate that a single-pass condenser offers a higher thermal load and smaller steam-side resistance.
