ShrinkDWorldwhat is CFBC boiler?? will you please explain it??😐 -
akpowerCFBC boiler are Circulating Fluidized Bed Combustion Boilers.The difference is fuel i.e. coal is burned in fluidized state. Earlier boilers had a static or rotating grate over which coal in lump size (50mm to 250mm ) was burned. Subequently, in pulverised boilers, coal was crushed to powder ( -70 mesh) & burned in suspended form. However in recent technique, coarser particles of coal (6 to 8 mm size) are burned in a bed of hot sand(2mm size) & lime (to reduce sulphur products)in fluidized state.The total mixture of bed material & ash is fluid in nature i.e. it flows like a fluid & ash is discharged outside furnace. I think I have cleared the idea.
