摘要

本文总结了某660mw蒸汽电厂大型海水冷却箱式冷凝器的性能分析。研究了海水温度和蒸汽质量流量对蒸汽冷凝器关键性能参数的影响。结果表明,冷却水温度的提高总体上有利于提高冷凝器的各项性能指标。另一方面,在蒸汽流量变化的情况下,效率和总换热系数几乎保持不变。冷凝器的效能并不是蒸汽流量变化的函数。此外,研究了蒸汽电厂热率与凝汽器冷却水的关系,发现提高冷却水温度会降低热率。相反,电厂的整体热效率由于发电量的减少而降低。

Performance Analysis of a Large-Scale Steam Condenser Used in a Steam Power Plant
This paper summarizes performance analysis of large-scale seawater-cooled box type condenser in a 660 MW steam power plant. Effect of seawater temperature and steam mass flow rate are investigated on the key performance parameters of steam condenser. Results indicated that improvement in the cooling water temperature generally is found favorable on the performance indicators of condenser. On the other hand, in the case of steam flow rate changing, effectiveness and overall heat transfer coefficient almost remain constant. Effectiveness of condenser isn’t found as a function of steam flow variation. Moreover, steam power plant heat rate is investigated as a function of cooling water of condenser and thus it is seen to be decreased in the result of improvement of cooling water temperature. Conversely, power plant overall thermal efficiency decreases due to reduction of power generation.
