摘要
分析机组长期真空偏低及厂用电率偏高的原因,分析机组负荷、循环水温度、循环水量与机组真空之间的变化规律,研究机组冷端优化的技术关键与运行特性;通过进行系统技术改造、运行方式优化等措施而达到机组冷端优化和降低厂用电率目的。
This paper analyzes the cause of the high rate of the low vacuum and high electricity rate of unit for a long time,analyzes the varied rules of the unit load,cycle water temperature,the quantity of circulating water and vacuum unit,and studies the key technology and operating characteristics of the turbine cold end optimization. Through the technical innovation system,operation mode optimization measures,it can optimize cold end system of unit and reduce the power consumption rate.
