An incinerator system and method wherein pieces of solid waste, such as fragments of wood, are disposed within a fluidized bed of an incinerator vessel, preferably the solid waste particles homogeneously. The fluidized bed is situated above a high temperature air delivery chamber at the bottom of the vessel and supports combustion or gasification of the solid waste particles in the fine granular material, preferably olivine, comprising the fluidized bed. Volatile matter given off by combustion is burned smokelessly in the vapor space immediately above the bed. All air flow is vortical being caused at least in part by the heat of the bed. Thus, fine particles comprising the bed and small pieces of solid waste are centrifuged back to the bed. Any solid waste retained within the vapor space are ultimately consumed. Special bed nozzles to which air is selectively channeled aids in improved combustion by defining a region in which tramp material is either trapped and stored, or trapped and removed. A novel fluidizing air system comprising parallel, spaced air ducts, creating uniform air distribution and nozzle discharge, accommodates continuous recirculation and purification of bed material during normal burner operation is provided. |
