Circulation Fluidized Bed Boiler (CFB Boiler)

? Boiler parameter range:

DHX10~100t/h Industry circulation fluidized bed boiler, QXF29~168MW circulation fluidized bed boiler

? Technical characteristics:

DHX circulation fluidized bed boiler has the range from low to high pressure, choosing the circulation fluidized bed firing technology. It has the remarkable effect on energy conservation and can suitable to various types of coal, especially to the low quality coal, the dealt biomass, waste slag and activated sludge. 

QXF series circulation fluidized bed hot water boiler chooses the horizontal single drum, forced circulation, furnace with fully membrane water cooling wall suspended structure, high temperature cyclone separator and fully steel frame of p arrangement. This type of boiler is stable & safety, high heating efficiency and energy conservation, suitable to the city central heating project.
