The ( FBC ) Fluidised Bed Combustion fired HAG system consist of a Radiative Heat Exchanger / Convective Heat Exchanger / HRU unit / Air pollution equp. With fluidised bed combustion furnace and controlled Fans.
Where the Cold Air Fed in to the Heat Recovery Unit ( HRU ) through C.A. Fan, gradually is heated and passes to Convective H.E. and than Radiative H.E. to Final Process.
As we consider the Flue gas path, Flue gas passes from furnace to Radiative H.E. to Convective H.E. than HRU unit to Air pollution eqp. to I.D. Fan and Chimney.
