660MW机组双背压凝汽器抽真空系统节能技术研究

Study on Energy Saving Technology of Double Pressure Condenser Vacuum System in a 660 MW Unit

针对某2伊660MW电厂对抽真空系统的节能技术改造项目的实施方案及成本进行了分析，提出采用新技术节能型真空泵在相同工况下运行，可使电耗降低60%～70%，节能效果显著，具有良好的经济效益和社会效益。

Based on a 2 伊660 MW power plant, the vacuum system energy saving renovation project plan and cost are analyzed. A new energy-saving vacuum pump is proposed to use, and which can reduce the power consumption by 60% ~70% in the same condition. The project has a remarkable energy saving effect, which can provide sufficient economic benefit and social benefit.
