Apparatus for the heating of carbonaceous materials by their partial combustion to carbon dioxide

Claim 1

AN APPARATUS FOR CONTROLLED PARTIAL COMBUSTION OF SOLID CARBONACEOUS FUEL TO CARBON DIOXIDE COMPRISING: (A) A PRESSURIZED VERTICAL VESSEL, (B) MEANS FOR GAS ISOLATING AT LEAST A PORTION OF THE VESSEL, (C) GYRATORY FEED MEANS FOR FEEDING HOT SOLID CARBONACEOUS FUEL CONTINUOUSLY DOWNWARD THROUGH THE VESSEL ADJACENT THE WALLS THEREOF AS AN ANNULAR CASCADE, (D) MEANS FOR INTRODUCING CONTROLLED AMOUNTS OF OXIDIZIER GAS AND INERT GAS THROUGH THE SIDE WALLS OF THE VESSEL INTO THE ANNULAR CASCADE OF SOLID FUELS AT A PREDETERMINED HORIZON FOR PRIMARY COMBUSTION. (E) A CONICALLY-SHAPED SECONDARY COMBUSTION MEMBER POSITIONED ABOVE THE HORIZON OF THE OXIDIZER GAS INTRODUCING MEANS AND OPEN TOWARD THE BOTTOM OF THE COMBUSTION CHAMBER DEFINING A SECONDARY COMBUSTION ZONE THEREIN AND THEREBELOW FOR THE COMBUSTION OF CARBON MONOXIDE TO CARBON DIOXIDE, (F) MEANS FOR INTRODUCING OXYGEN THROUGH THE CONICALLY SHAPED SECONDARY COMBUSTION MEMBER FOR BURNING CARBON MONOXIDE IN THE SECONDARY COMBUSTION ZONE TO CARBON DIOXIDE AND ALLOWING THE HEAT TO BE RADIATED ON TO THE ANNULAR CASCADE OF SOLID FUEL, (G) A TURBULENCE ARRESTOR PLATE POSITIONED BELOW THE LEVEL OF THE OXIDIZER GAS INTRODUCING MEANS AND AIDING THE CONICAL SHAPED SECONDARY COMBUSTION MEMBER IN PREVENTING SOLID CARBONACEOUS FUEL FROM ENTERING THE SPACE WITHIN THE ANNULAR CURTAIN CASCADE ABOVE THE LEVEL OF THE OXIDIZER GAS INTRODUCING MEANS, (H) AND A PASSAGEWAY IN THE APEX OF THE CONICALLYSHAPED COMBUSTION MEMBER FOR WITHDRAWING THE PRODUCTS OF COMBUSTION.

Claim 2

AN APPARATUS FOR CONTROLLED PARTIAL COMBUSTION OF SOLID CARBONACEOUS FUEL TO CARBON DIOXIDE COMPRISING: (A) A PRESSURIZED VERTICAL VESSEL, (B) MEANS FOR GAS ISOLATING AT LEAST A PORTION OF THE VESSEL, (C) GYRATORY FEED MEANS FOR FEEDING HOT SOLID CARBONACEOUS FUEL CONTINUOUSLY DOWNWARD THROUGH THE VESSEL ADJACENT THE WALLS THEREOF AS AN ANNULAR CASCADE, (D) MEANS FOR INTRODUCING CONTROLLED AMOUNTS OF OXIDIZIER GAS AND INERT GAS THROUGH THE SIDE WALLS OF THE VESSEL INTO THE ANNULAR CASCADE OF SOLID FUELS AT A PREDETERMINED HORIZON FOR PRIMARY COMBUSTION. (E) A CONICALLY-SHAPED SECONDARY COMBUSTION MEMBER POSITIONED ABOVE THE HORIZON OF THE OXIDIZER GAS INTRODUCING MEANS AND OPEN TOWARD THE BOTTOM OF THE COMBUSTION CHAMBER DEFINING A SECONDARY COMBUSTION ZONE THEREIN AND THEREBELOW FOR THE COMBUSTION OF CARBON MONOXIDE TO CARBON DIOXIDE, (F) MEANS FOR INTRODUCING OXYGEN THROUGH THE CONICALLY SHAPED SECONDARY COMBUSTION MEMBER FOR BURNING CARBON MONOXIDE IN THE SECONDARY COMBUSTION ZONE TO CARBON DIOXIDE AND ALLOWING THE HEAT TO BE RADIATED ON TO THE ANNULAR CASCADE OF SOLID FUEL, (G) A TURBULENCE ARRESTOR PLATE POSITIONED BELOW THE LEVEL OF THE OXIDIZER GAS INTRODUCING MEANS AND AIDING THE CONICAL SHAPED SECONDARY COMBUSTION MEMBER IN PREVENTING SOLID CARBONACEOUS FUEL FROM ENTERING THE SPACE WITHIN THE ANNULAR CURTAIN CASCADE ABOVE THE LEVEL OF THE OXIDIZER GAS INTRODUCING MEANS, (H) AND A PASSAGEWAY IN THE APEX OF THE CONICALLYSHAPED COMBUSTION MEMBER FOR WITHDRAWING THE PRODUCTS OF COMBUSTION.
