    摘要: A method and apparatus for combustion of a solid carbonaceous material in which the solid carbonaceous material is preheated and at least a portion thereof pyrolyzed on a stoker grate disposed in the lower portion of a combustion chamber to produce pyrolysis products. Overfire oxidant is then introduced into the combustion chamber above the stoker grate to ensure complete combustion of combustibles in the products of combustion generated by combustion of the solid carbonaceous material and the pyrolysis products. Preheating and pyrolysis of the solid carbonaceous material is carried out by the introduction of a pyrolysis agent directly into the bed of solid carbonaceous material.

    摘要: A process and apparatus for combustion in which a combustible material is introduced into a combustion chamber and oxidant is supplied to the combustion chamber. The combustible material is burned, and forming a primary combustion zone. A mixture of flue gases and flyash having an organic content is injected into the combustion chamber downstream of the primary combustion zone to create an oxygen-deficient reburn zone, thereby lowering the temperature of combustion, reducing the NO.sub.x content of the flue gases, and reducing the potential for NO.sub.x formation in a tertiary oxidizing combustion zone disposed downstream of the oxygen-deficient reburn zone.

    摘要: A process and apparatus for oxygen-enriched combustion of a fuel in an industrial furnace in which a preheated primary oxidant from a heat exchanger and a fuel to be combusted are introduced into a combustion chamber and ignited, a secondary oxidant having an oxygen concentration in excess of the concentration of oxygen in air is introduced into the combustion chamber downstream of the flame, and the resulting combustion products are exhausted. In accordance with one embodiment, the secondary oxidant comprises preheated oxidant aspirated from the heat exchanger using industrial-grade oxygen, resulting in an oxygen-enriched mixture being injected into the combustion chamber downstream of the flame. As a result, NO.sub.x emissions are reduced without adverse effects on the overall furnace operation.

    摘要: A method and apparatus for producing radiant heat in which a mixture of fuel and primary combustion oxidant is introduced into a combustion chamber having a heat radiating wall, which mixture has less than a stoichiometric requirement for complete combustion of the fuel, and igniting the mixture, forming heated partial combustion products. At least a portion of the heat in the heated partial combustion products is transferred to the heat radiating wall. The heated partial combustion products are passed from the combustion chamber into an exhaust gas plenum disposed adjacent to the combustion chamber. A secondary combustion oxidant is introduced into the exhaust gas plenum in an amount sufficient to complete combustion of the partial combustion products, forming exhaust gases. Heat in the exhaust gases is transferred to the primary combustion oxidant disposed in a combustion oxidant plenum disposed adjacent to said exhaust gas plenum.

    摘要: A process and system for release and recovery of methane from subterranean methane hydrate deposits in which heated CO2 is used to displace methane from the methane hydrate deposits and a portion of the displaced methane is routed to a combustion device proximate the deposit for combustion in-situ, generating heated CO2 which is introduced into the deposit, displacing additional methane, a portion of which is routed to the combustion device, thereby providing a substantially self-sustaining process. Portions of the displace methane not routed to the combustion device are captured for use elsewhere.
