630～650℃参数机组锅炉关键材料分析
|
摘要
提高燃煤发电机组效率是我们不懈的追求,国内正在研发630～650℃超超临界机组(ultra supercritical,USC),而蒸汽参数的提高离不开材料技术。本文对国内外超超临界燃煤机组锅炉耐高温材料的现状以及材料发展的沿革进行了回顾,分析了现有材料对机组参数进一步提高的限制因素,并对国内外研发中的新材料进行了分析介绍,对630～650℃超超临界机组锅炉关键耐高温材料进行了分析。
It is our unremitting pursuit to improve the efficiency of the coal-fired units, the USC unit at 630 ～ 650℃parameter is being developed in China, and material technology is the key factor. This paper reviews the current situation of materials for USC boiler and the evolution of material development,explains the limiting factors for the further improvement of the parameters of the USC coal-fired units, and describes the new materials in research and development,then analyzes and the key materials to the 630 ～ 650℃ parameter USC coal-fired boiler.
