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.
