摘要
针对350MW超临界机组2台给水泵运行方式耗用大量厂用电的实际问题,进行了不同工况参数下的电泵出力试验,提出了低负荷阶段单电泵运行的优化方案。运行结果表明:单电泵运行方式可满足机组73%以下负荷工况的安全运行需求,降低厂用电耗效果明显,对火电厂的经济运行具有重要意义。
A considerable amount of plant for the 350 MW supercritical unit 2 pump operation mode of electricity,the output test pump different working parameters,the optimization scheme of low load stage single pump operation. Operation proves: single pump operation mode can meet the demand of safe operation of unit 73% the following load,reduce plant energy consumption effect is obvious,has the important meaning and economic operation of thermal power plant.
