摘　　要：通过对近年我国经济发展现状和电力结构特点的分析、研究,采用电力弹性系数估测了我国未来20年的电力需求情况,基于5个火力发电可能性发展方案,对未来20年火电厂用水情况进行了预测、分析。研究表明,在未来我国的火力发电建设中,除应逐渐减少直流冷却方式,加快发展亚临界、超临界和超超临界机组,加强滨海地区海水直接冷却技术的应用,大力实施空冷技术等之外,还应加大节水型技术的开发和规模化应用力度。Through the analysis of the economic development situation in China and the characteristics of power structure in recent years, the electricity demand situation in China in the next 20 years was predicted with using electricity elasticity coefficient. Based on the five feasible power development programs, the water consumption of thermal power plants in the next 20 years were predicted and analyzed. The results show that, in the future thermal power construction in China, the DC cooling unit should be gradually reduced, the subcritical, supercritical, and ultra supercritical units should be constructed speedily, as well as the application of direct cooling technology with sea water in coastal region and the air-cooling technology should be strengthened. In addition, the development and large,scale application of water-saving technology should be also strengthened.
