<p>LOW POLLUTION INCINERATION OF SOLID WASTE An incinerator system and method wherein pieces of solid waste, such as fragments of wood, are conveyed in such fashion as to become disposed within a fluidized bed of an incinerator vessel. Preferably the solid waste particles are caused to be somewhat homogeneously dispersed within the fluidized bed. The solid waste particles may be "pre-dried" or moisture may be added to the particles prior to deposition in the fluidized bed for optimum results, depending upon circumstances. In one embodiment, the fluidized bed is situated above an air delivery chamber at the bottom of the vessel and supports combustion of the solid waste particles in the fine granular material comprising the fluidized bed. The fine granular material is supported by a perforated plate. The air delivery system channels high temperature air into and up through the fluidized bed until operating temperature is reached and 80 channels ambient air thereafter. Volatile matter given off by combustion of the solid waste particles in the fluidized bed is burned smokelessly in the vapor space immediately above the bed.</p> |
