我国正处于加快转变经济发展方式的关键时期，能源需求持续增长，生态环境保护和气候压力对社会经济可持续发展的约束日渐严重。我国一次能源的结构特点决定了我国电力供应以燃煤发电为主的格局，而燃煤发电既是用煤大户也是用水大户，同时还是污染物排放大户。优化煤电发展，向集约化、环保化发展转变是电力工业的战略调整。本文论证了我国煤电技术向清洁化发展的战略思路，简要回顾了超超临界技术和大型空冷技术的研发成果与产业化推广现状，论述了这两项先进煤电技术对电力工业发展转型的支撑作用。

China is standing in a key period of accelerating transformation of its economic growth model. As the demand of energy is continuously growing, the pressure of environmental protection and climate change increasingly restrain China's sustainable economic and social development. The characteristics of the primary energy mix determine the power supply pattern in China, which is dominant with coal fired power generation. Coal fired power generation is a big consumer of coal and water and also a big contributor to pollutants. The strategic adjustment of the electric power industry is to optimize coal fired power development and transit to intensive and environment friendly development mode. This paper demonstrates the strategy of clean coal power technology in China, reviews the R & D achievements and industrial commercialization of ultra super critical technology and large scale air cooling technology, and expounds the supporting role of these two advanced coal fired power generation technologies in transforming the electric power industry.
