为了探索循环水节能改造方法,以某热电厂节能改造为例,通过改造原循环水管路,降低凝汽器的真空度,在凝汽器出口之后加装尖峰热网加热器,利用减压减温后的新蒸汽,或其他汽源加热热网水等方法,实现循环水供暖,从而提高热源的利用率。此节能方案可为其他同类型热电厂节能改造提供借鉴,也可为电力需求侧管理和节能减排工作提供参考。
In order to explore the energy-saving retrofit method of circulating water, take the energy-saving retrofit of a thermal power plant as an example, retrofit the original circulating water pipeline to reduce the vacuum degree of the condenser, install the peak heater, After the new steam, or other steam source heat heating network water and other methods to achieve circulating water heating, thereby enhancing the utilization of heat sources. This energy-saving scheme can provide reference for energy-saving retrofitting of other thermal power plants of the same type, and also provide reference for electricity demand-side management and energy conservation and emission reduction.
