Experimental studies on combustion of cattle manure in a fluidized bed combustor
Manure from cattle feedlots is a renewable energy source which has the potential of supplementing the existing fossil fuels. But the heat content of manure is rather low. Since the fluidized bed combustion technology has been used for the energy conversion of marginal fuels, such a technology is being explored for the combustion of feedlot manure. A fluidized bed combustor of 0.15 m (6 in.) diameter was used for the combustion tests on manure. Experiments were conducted with -20 to +20 percent excess air and at bed temperatures ranging from 600/sup 0/C (1112/sup 0/F) to 800/sup 0/C (1472/sup 0/F). Experimental data revealed that the gasification efficiencies ranged from 90 to 98 percent, while the combustion efficiencies varied from 45 to 85 percent.
