本文介绍了作者对水垢—汽轮机冷凝器真空度影响状况的调查及其水垢引起的经济损失估计,叙述了自转塑料纽带的连续清洗和传热强化原理,试验表明自转塑料扭带的连续清洗能力能够满足冷凝器污垢清洗的要求,并且兼有幅度为9％-15％的传热强化作用,长时间的考核试验运行没有发现扭带对铜管壁的磨损问题,计算分析说明连续清洗纽带对提高机组真空度、出力和增产增效的作用显著。 This paper presents an investigation of the influence of the vacuum on the scale-turbine condenser vacuum and the estimated economic loss caused by the scale. The principle of continuous cleaning and heat transfer enhancement of rotating plastic strands is described. The experiments show that the continuous cleaning capability of rotating plastic straps can Meet the requirements of the condenser dirt cleaning, and both the rate of 9% -15% heat transfer enhancement, a long time of the test run did not find the twisted pair of copper wall wear and tear, calculation and analysis shows that the continuous cleaning of the link to improve Unit vacuum degree, output and efficiency of significant effect.
