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.
