afbc boiler heat transfer area calculation

There are two types of combustion beds according 3T’s of combustion which are Residence Time, Temperature of Bed, Turbulence . AFBC (Atmospheric Fluidized Bed Combustion) : Comparatively lesser residence time, turbulence and lower combustion efficiency and lower desulfurization.
