Integrated process for preparing and firing bagasse and the like for steam power generation

Patent ·
OSTI ID:6482522
An integrated method is disclosed for preparing and suspension firing of bagasse and the like as the primary fuel for steam power generation in a cane sugar refinery. The method comprises mixing wet bagasse with de-ashed hot flue gases of a steam boiler, thereby drying it; separating bagasse dried thereby from the drying flue gases, capturing substantially all suspended dust; sizing the dried bagasse; directing bagasse fines to temporary storage while grinding and resizing any oversize bagasse; metering out and pneumatically suspending the fines, providing a smooth-flowing fuel responsive to a burner fuel feed control means; combusting the suspended fuel in a scroll feed type burner firing the steam boiler; de-ashing the combustion effluent, and utilizing the resultant flue gases for drying wet bagasse. Alternatively, the wet bagasse may be dried partially by de-ashed hot flue gases and partially by a bagasse fired supplementary hot air dryer, thereby further improving boiler operation efficiency.
