Organic conversion system

Claim 1

Apparatus for the pyrolytic conversion of organic waste material into a fuel product comprising: three generally vertically positioned substantially concentric conduits wherein the innermost conduit is open at both ends and forms a pyrolysis chamber, said pyrolysis chamber being provided with an organic waste material inlet means enabling the introduction of organic waste material into said innermost conduit from outside of said apparatus; the middle conduit is open at the bottom end and forms a combustion chamber having oxygen inlet means positioned at the bottom thereof, said combustion chamber functioning to enable the regeneration of hard, dense, particulate matter by combustion and to enable heating of said pyrolysis chamber by channelling combustion gases through said combustion chamber along the outside of said pyrolysis chamber into a gas outlet chamber formed at the top end of said conduit closing off said top end said outlet chamber enabling the discharge of said combustion gases out of said apparatus, said innermost conduit extending through said gas outlet to open into the outermost conduit; said outermost conduit closed at both ends to enclose said innermost and middle conduits and form a collecting chamber, said collecting chamber functioning to enable the recirculation of said hard, dense, particulate matter within said apparatus, said outermost conduit having a product outlet to enable removal of fuel product from said apparatus, and a char outlet at the bottom thereof to enable the removal of char from the apparatus; an arcuate shaped static cyclone positioned over the top of said innermost conduit, said cyclone functioning to separate hard, dense, particulate matter exiting said innermost conduit from product gas exiting said innermost conduit; a seal comprising a fluidized bed of said hard, dense, particulate matter and formed between said middle conduit and outermost conduit, said seal functioning to separate product gases from combustion gases.
