ABSTRACT:
A fluidized bed reactor and system and method utilizing same for the combustion of waste fuels in which the reactor vessel is divided into three vessels. Waste fuel is introduced into the fluidized bed within one vessel where it is mixed with bed make-up material that is controlled to provide an ideal environment for the generation of pyrolytic gases. The fluidized bed material is pneumatically and gravitationally conveyed downwardly, and injected into a fluidized bed within the second vessel where the involatile organic material undergoes combustion in an oxidizing atmosphere. The bed material in the second vessel is pneumatically conveyed upwardly and divided into two portions, one of which is recycled back to the first vessel. The other portion of the bed material in the second vessel is circulated to a fluidized bed within the third vessel where heat is recovered. The bed material in the heat recovery vessel is gravitationally conveyed back to the second vessel to regulate the temperature in the latter vessel.
