摘要
介绍了超(超)临界机组高效节能的特点,从钢种分类、发展脉络、应用范围、焊接特点等方面对应用于超(超)临界机组中的新钢种进行了论述。指出,超(超)临界机组是火力发电发展的新方向,发展高效率的火力发电机组的关键技术之一是开发耐高温性能更好的耐热钢,使其能用于更高的温度区间。
Energy efficient characteristics of ultra-supercritical unit power generation units are presented. Classification, development, application and welding characteristics of new types of steel for ultra-supercfitical units are discussed. It is pointed out that the ultra-supercritical unit power generation units is a new direction for the development of highly efficient SC, USC power generation units. It is one of the key technologies to develop better high temperature performance of the heat-resistant steel, so that it can be used in a higher temperature range.
