Thermal power generation has ranked the first in water consumption of industry in our country, at the same time our country is one of the poorest countries in water resource, it is necessary to take some measures to reduce water resource consumption and containment discharge specifically by accounting thermal power generation's footprint. This article analyses the research status on thermal power generation from domestic and oversea, and finds that the results of research are limited and a major part of scholars are focusing on one specific process only. Therefore this article based on the theory of water footprint has confirmed the boundary of thermal power generation's water footprint, established the accounting model of thermal power generation's water footprint, calculated the input of energy, the treatment of raw material, the water consumption used in diluting waste water and direct water intake respectively, and took a coal-fired power plant whose installed capacity is 300MW for example, and accounted its water footprint roundly. In the end, guided by the core of water saving in thermal power plant which lies in water saving and the reduce of drainage, this article comes forward some suggestion about water saving measures in thermal power plant, and provides reference for making some specific adjustment and improvement for thermal power plant and takes measures to reduce the consumption of water resource and the amount of contaminant. |
