Combustion Disposal of Manure Wastes and Utilization of Byproducts.

NTIS: PB 206 892 :9 pages
Agricultural manure wastes were combusted in a fluidized-bed reactor and a small rotary kiln as a method for disposal combined with utilization. As much as 90 percent weight reduction and 85 percent volume reduction was obtained by burning the manures. Dry manure burning in the fluid-bed reactor was self-sustaining, whereas wet manure required drying before it was burned in a rotary kiln using additional heat. Heat balance estimations indicated that preheating would be required to burn wet manure fed directly into the fluid-bed reactor. However, the estimation indicated that no extra heat was needed in the process if the wet manure was predried with exhausted combustion gases before feeding to the fluid bed. The burned residues were pelletized and found suitable for use both as a potassium and phosphorus fertilizer and as a lime soil conditioner.
