Advanced Swirling Fluidized Bed Combustion (sfbc) Process and Unburned Carbon Analysis for Biomass Waste Disposal

Increasing size and concentration of production is a long-established and continuing trend in the poultry producing industry. The size of poultry litter produced in this industry shows a sustained and increasing trend too. Daily fresh litter/manure output per is about 30 kg/100 birds. For example, the size of Delmarva broiler farms is average 50,000 heads, and the daily poultry litter production is 15,000kg. [1,2] The poultry litter/manure has historically been used as a source of plant nutrients and as a soil amendment. However, in areas of intense poultry production, over-fertilization of pasture lands with poultry manure occurs. The excessive nutrients have caused environmental problems, such as ground water run-off pollution by phosphorus. The thermal treatment of poultry litter/manure has been proven to be as an alternative method to treat the poultry litter. Juan et al. has presented that the poultry litter (basically constituting C, H, O, N, S) can be used an alternative fuel to the power generation. [3] The objectives of this research are to: (1) apply the Fluidized Bed Combustion technology to burn the poultry litter; (2) find the carbon combustion efficiency based on the unburned carbon from the flying ash and residue; and (3) explore different operation condition effect on the carbon combustion efficiency.
