摘要： A method and apparatus for combustion of a fuel in which a first-stage fuel and a first-stage oxidant are introduced into a combustion chamber and ignited, forming a primary combustion zone. At least about 5% of the total heat output produced by combustion of the first-stage fuel and the first-stage oxidant is removed from the primary combustion zone, forming cooled first-stage combustion products. A portion of the cooled first-stage combustion products from a downstream region of the primary combustion zone is recirculated to an upstream region of primary combustion zone. A second-stage fuel is introduced into the combustion chamber downstream of the primary combustion zone and ignited, forming a secondary combustion zone. At least about 5% of the heat from the secondary combustion zone is removed. In accordance with one embodiment, a third-stage oxidant is introduced into the combustion chamber downstream of the secondary combustion zone, forming a tertiary combustion zone.

摘要： A multi-stage heating apparatus having a first stage combustion chamber, a second stage combustion chamber, a primary porous matrix chamber disposed between the first and second stage combustion chambers, a secondary porous matrix chamber, heat exchanger tubes for transfer of heat from the combustion products to a working fluid, a recirculation device for recirculating combustion products in the first and second stage combustion chambers to the root of flames therein. A mixture of fuel and primary oxidant is introduced into the first stage combustion chamber, and the products of combustion therein are conveyed to the porous matrix chamber disposed between the first and second stage combustion chambers. After undergoing intensive heat transfer in the porous matrix chamber, the cooler products of combustion flow into the second stage combustion chamber forming additional products of combustion. The products of combustion then flow to a second porous matrix chamber in which they undergo further intensive heat transfer. From there, the products of combustion pass through an economizer for preheating a working fluid and through a condenser for removing moisture in the combustion products prior to being exhausted.

摘要： A furnace for combustion wherein a combustion chamber is configured such that waste can be advanced from a drying zone, to a combustion zone, to a burnout zone, and then into an ash pit. An air source provides air for drying, combustion and burnout in a primary combustion zone (PCZ). Fuel or a fuel/recirculated flue gas mixture is injected above the PCZ to create a mostly reducing substoichiometric secondary combustion zone (SCZ), to reduce NO.sub.x and decompose other nitrogen bearing compounds entering the SCZ. Vitiated air is injected into the combustion chamber above the mostly reducing SCZ. A process for combustion of the waste includes introducing the waste into the combustion chamber, advancing the waste through the combustion chamber, supplying combustion air to the combustion chamber for drying and combusting the waste and final ash burnout, and removing ash products from the combustion chamber. The fuel or fuel/recirculated gas mixture is supplied into the combustion chamber to create substoichiometric conditions for NO.sub.x reduction and nitrogen bearing compounds decomposition. Overfire air is supplied into the combustion chamber above the substoichiometric zone for thorough mixing and at least partial burnout of combustibles contained within the waste/fuel combustion products.

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.

摘要： A process for combustion of the combustible material includes introducing the combustible material into the combustion chamber, advancing the combustible material through the combustion chamber, supplying combustion air to the combustion chamber for drying and partially combusting the combustible material and final ash burnout in a primary combustion zone, and removing ash products from the combustion chamber. The fuel or fuel/carrier fluid mixture is supplied into the combustion chamber to create an oxygen deficient secondary combustion zone for NO.sub.x reduction and other nitrogen bearing compounds decomposition. An oxidizing fluid is supplied into the combustion chamber above the oxygen deficient secondary combustion zone for thorough mixing with combustion products and at least partial burnout of combustibles in an oxidizing tertiary combustion zone. A furnace for combustion in accordance with this process is also disclosed wherein a combustion chamber is configured such that combustible material can be advanced from a drying zone, to a combustion zone, to a burnout zone, and then into an ash pit. An air source provides air for drying, combustion and burnout in a primary combustion zone. Fuel or a fuel/carrier fluid mixture is injected above the primary combustion zone to create an oxygen deficient secondary combustion zone, to reduce NO.sub.x and decompose other nitrogen bearing compounds entering the secondary combustion zone. An oxidizing fluid is injected into the combustion chamber above the oxygen deficient secondary combustion 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.
