This work investigates the combustion of five kinds of Nigerian biomass in an atmospheric bubbling fluidized bed combustor. The combustion chamber is a steel cylinder with 145mm internal diameter and 2400mm height. Tests were conducted on coconut shell, rice husk, corn cobs, groundnut husk and sawdust-wood. Excess air was varied for each fuel. Temperature variation along the combustor height and the flue gas emissions from the combustor exhaust were measured and thereafter the combustion efficiency for each biomass fuel was determined. Results gave maximum combustion efficiencies of 96.6%, 96.7%, 96.2%, 97.9% and 98.2% for coconut shell, rice husk, corn cobs, groundnut husk and sawdust-wood respectively at 80% excess air except for coconut shell where it occurred at 65% excess air. The major gaseous (CO and NO) emissions were at levels which were less than the U.K. environmental emission limits permitted for new fluidized bed combustor of biomass fuels.
