摘　　要：针对华能大连电厂3、4号机组由于调停、检修、技改等原因频繁启停而导致电泵运行时间较长的情况,提出了利用辅汽驱动汽泵替代电泵运行的技术方案[1],优化了机组运行方式,降低了厂用电率,节能效益显著,同时提高了机组运行可靠性,为同类型给水系统机组提供借鉴。According to the actual production experience of Huaneng Dalian Power Plant,a new operation project of TDBFP driven by auxiliary steam replacing MDBFP is applied,which can save a lot of energy consumption,optimize the operation mode,promote the security and flexity. This new operation project can bring significant experience for other power plant with similar boiler-feedwater pump system.
