摘要:

针对某热电厂330MW亚临界机组电动电泵耗电量大的问题,进行了不同工况下的电泵出力试验。拟定单电泵运行方式,可满足机组 65%以下负荷工况的安全运行需求。机组低负荷滑压运行,降低厂用电效果明显。

Abstract:

Based on the problem of high power consumption of a heat and power plant’s 330MW sub critical unit electric pump, load test was carried out. Single unit operation is able to satisfy 65% or under load working condition. Power consumption reduction is significant while sliding pressure operation.
