Abstract:
A waste material processing apparatus, comprising:(a) a casing having a top and bottom and a plurality of sides defining a pyrolysis chamber for receiving and pyrolyzing said waste materials into fluid materials, said pyrolysis chamber having an upper portion for temporarily receiving said fluid materials;(b) a mass of refractory material contained in said casing, spaced below said upper portion of said pyrolysis chamber and extending between said sides, said refractory mass including an upper surface defining a bottom of said pyrolysis chamber, said upper surface supporting said waste materials and an ash residue from said waste materials and further wherein said refractory mass includes an end spaced from a first one of said sides of said casing so as to define an ash residue collection cavity;(c) means for selectively stirring said ash residue positioned adjacent to said upper surface of said refractory mass so that at preselected times said means for selectively stirring said ash residue also removes said ash residue from said upper surface wherein said means for stirring and removing comprises at least two degrees of freedom of movement; and(d) a system of tunnels defined within said refractory mass being spaced below said upper surface, said system of tunnels including (i) at least one inlet defined in said refractory mass in at least one side and below said upper surface, said inlet communicating with said upper portion of said pyrolysis chamber so as to receive a flow of said fluid material, and (ii) an outlet defined in a bottom portion for discharging the flow of said fluid materials from said system of tunnels.
