自主研发600 MW超临界CFB锅炉的设计研究

为进一步发展和提高大容量超临界循环流化床锅炉技术,在研制首台国产210MW和330MW循环流化床(CFB)锅炉的基础上,系统研究了CFB锅炉大型化的关键技术,开展了国产600 MW超临界CFB锅炉的方案设计,对锅炉的炉型结构、关键部件、汽水系统及辅助系统进行了分析和设计研究.介绍了国产600MW超临界CFB锅炉结构:采用"H"型整体布置,6台高温旋风分离器布置在炉膛两侧,配有相应的紧凑式分流回灰换热器(CHE),炉膛水冷壁为垂直管圈结构,双回路给煤系统可保证均匀可靠地向炉内送入燃料.该锅炉技术方案可为工程应用奠定技术基础.

Research and design of domestic proprietary 600 MW supercritical CFB boiler

In order to develop large capacity supercritical circulating fluidized bed (CFB)boiler technology,based on research and manufacture of first domestic proprietary 210 MW and 330 MW CFB boiler, the key technologies of large CFB boiler have been researched systematically, the design of domestic proprietary 600 MW supercritical CFB boiler have been performed, the construction of boiler configuration, the key components, the steam-water system and the auxiliary system were analyzed and designed. The domestic proprietary 600 MW supercritical CFB boiler adopted H-shaped layout, six unit cyclones and compact splitting heat exchanger (CHE) located two side of furnace, water wall was vertical tubes, two loops feeding coal system assured fueling reliably and uniformly. The boiler scheme can supply a technology basis for engineering application.
