火力发电厂凝汽器真空系统节能应用研究

Research on Energy-saving Application of Condenser Vacuum System in Thermal Power Plant

在火力发电厂凝汽器的原有机组真空系统上增加一套高效罗茨真空泵组,在不改变原有真空泵及系统的功能情况下,不仅替代原有液环泵维持真空前提下节电效果明显,且适当的增加抽气能力还能在同等负荷下获得更好的凝汽器真空度,从而取得良好的经济效益。

A high-efficiency Roots vacuum pump set is added to the original vacuum system of the condenser of a thermal power plant.Without changing the function of the original vacuum pump and the system,the electricity saving effect is obvious under the premise of replacing the original liquid ring pump to maintain the vacuum,and an appropriate increase in the pumping capacity can also obtain a better vacuum degree of the condenser under the same load,so as to achieve good economic benefits.
