Abstract
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°C (1112°F) to 800°C (1472°F).
Experimental data revealed that the
gasification efficiencies ranged from 90 to 98
percent, while the combustion efficiencies
varied from 45 to 85 percent.
