给水泵运行方式经济性分析研究

Economic Analysis of Feed Pump Running

由于电力生产的特点,火电厂主要热力设备的运行工况必然是不断变化,以适应外界负荷需求的变化,这就要求锅炉给水泵要有敏捷的负荷跟随性和经济性,从而达到减少厂用电率、降低煤耗。通过对定速泵和变速泵的特性分析,全面论述了实际运行工况中定速泵和变速泵的选择及优缺点。

Due to the characteristics of the power production, the operating conditions of main thermal equipment in thermal power plant must be constantly changing to adapt to changes in the external load demand, which requires boiler feed pumps have agility load following and economy, so as to reduce the auxiliary power consumption rate, and coal consumption. Through the analysis of the characteristics of the fixed-speed pumps and variable speed pumps, the selection and the advantages and disadvantages of the fixed speed pumps and variable speed pumps in actual operating conditions were comprehensively discussed.
