Abstract
Air pollutants from the fluidized bed municipal incinerator were investigated. The incinerator was able to incinerate 150 t refuse in a day. That discharged NOx, dust and odor in much the same with the step-grate stoker type municipal incinerator. But, that discharged CO and THC in higher, SO2 in lower concentration than the step-grate stoker type municipal incinerator. High HCl removal efficiency was gained by excess CaCO3injection into the furnace.
O2 and air pollutants' concentration were changing widely corresponding with the amount of refuse into the furnace.
Especially, when the amount of refuse into the furnace increased suddenly, O2 concentration often decreased quickly under some percent. Then CO and THC, which was rich in aromatic or non-saturated hydrocarbons, were discharged in high concentration. Black smoke was discharged, too.
