基于水功能的火力发电厂用水效率评价方法研究

火力发电用水是我国工业用水的主要用水户之一。面向国家工业节水的需求，针对我国火力发电行业现有的用水效率评价指标的局限性，考虑水的物理化学特性，通过分析水在火力发电厂生产环节中所起到的功能和作用，提出了一个有物理机制的火力发电厂用水效率评价新方法，并用一个例子对此方法进行了应用，结果表明该方法可行，具有广阔的应用前景。

Methodology of water-use efficiency assessment for thermal power plant based on the function of water

The thermal power plant is a major water user of industrial water in China. For the sake of na- tional industrial water saving, a new methodology of water-use efficiency assessment for the thermal power plant is proposed on the consideration of the limitations of the existing indicators. The new methodology, which has a physical mechanism, is based on the basic physical and chemical properties of water and the analysis of water＇s function in the production processes of thermal power plants. The proposed methodology is applied to a case study, which shows the new methodology has a promising application.
