摘要
通过对望亭发电厂2台660MW超超临界机组配备的双背压凝汽器压差偏小的情况进行分析研究,结合原真空抽气管路设计情况,对该厂4号机组双背压凝汽器的真空抽气管路进行优化改造,并对改造效益进行了计算评估。
By analysising the situation that double condenser pressure difference is low of two 660MW ultra supercritical unit in Wangting power plant, according the design of original vacuum gas pipeline, Optimization and transformation on double pressure condenser vacuum gas pipeline of No. 4 unit was finished, then calculating and assessing the renovation.
