[Combustion characteristics of municipal solid waste in fluidized bed]

For the experimental investigation on the combustion characteristics of Municipal Solid Waste(MSW) in Fluidized Bed, a lab scale Fluidized Bed facility was constructed. Single and mixed municipal solid waste burning in Fluidized Bed showed that dry waste can be burnt quickly at the bed temperature of 500 degrees C, and furnace temperature increased about 30-50 degrees C. Many kinds of combustion runs were conducted in this Fluidized Bed combustion facility. The parameters examined were air flow rate(from 5.5 m3/h to 7.5 m3/h), form of fuels(scrap or whole), moisture content and so on. Concentration of CO2, CO, SO2 and NOx in the flue gas were monitored and recorded every 5 seconds. The temperatures along the reactor were recorded every 10 seconds.
