摘　　要：高效燃煤发电技术一直是能源高效利用的先锋。当前主流的超(超)临界燃煤发电技术发展经历了3个阶段,技术在全球范围内逐渐成熟;在材料工业发展的支持下,朝着700℃等级先进超超临界技术的方向发展;并已逐步解决商业化应用的关键技术难题,迈向第4个重要发展阶段。受制于如钢材和加工等基础工业领域的薄弱条件,中国在高效燃煤发电技术研发方面长期落后于发达国家;但经过长期追赶,当前已逐渐接近世界先进水平,且在700℃等级先进超超临界技术研发方面,也取得了可喜成绩。在高效燃煤发电技术应用等方面,中国近40年来发展迅猛,当前中国的煤电机组煤耗水平已达到欧洲诸国的先进水平。进一步发展材料等基础工业,从主机设备、系统布置等方面进行设计创新,仍然是高效燃煤发电技术发展的关键。The efficient coal-fired power generation technology has always been a pioneer for the efficient use of energy. The current main(ultra) supercritical(USC) coal-fired power technology has suffered three stages. The research of USC coal-fired power technology of 700 ℃ class has been launched out, and most of the key issues has been worked out in USA, EU and Japan. Restrained from the weak conditions of basic industries like steel and processing, the research of coal-fired power industry in China has lagged behind the developed countries for long-term. Fortunately, the situation has been improved greatly thanks to the endeavor of the whole colleagues during the past several decades, and a lot of achievement has been achieved in the research of USC of 700 ℃ class. Besides, the installation and operation of efficient coal-fired power units has led the world level as a result of fast development in power industry over the past several decades. While, further development of the basic industry like steel and processing remains to be the bottleneck for fundamental development of the efficient coalfired power technology.
