    摘要: A low pollutant emission, high efficiency cyclonic burner and cyclonic combustion process for firetube boilers and heaters in which the combustion air required for complete combustion is introduced into the cyclonic burner in stages. Fuel and primary combustion air in an amount of about 30% to about 90% of the stoichiometric requirement for complete combustion of the fuel are tangentially injected into a primary combustion zone of a combustion chamber within the burner. Secondary combustion air in an amount of about 10% to about 90% of the stoichiometric requirement for complete combustion of the fuel is introduced into a secondary combustion zone in the combustion chamber downstream of the primary combustion zone. The combustion chamber walls are cooled to maintain the combustion chamber temperature between about 1600.degree. F. and 2400.degree. F.

    摘要: A combustion process and apparatus for simultaneously reducing nitrogen oxides, sulfur oxides and hydrogen chloride in a high temperature furnace. A combustible material is introduced and combusted within the furnace, forming a primary combustion zone. Combustion air, sorbent and a first portion of hydrocarbon fuel are mixed and combusted within a calciner to form a product gas/calcined sorbent mixture. The product gas/calcined sorbent mixture and a remaining portion of fuel are injected into the furnace, forming an oxygen deficient secondary combustion downstream of the primary combustion zone. Overfire air is injected into the furnace, forming an oxidizing tertiary combustion zone downstream of the oxygen deficient secondary combustion zone.

    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 for combusting sulfur and nitrogen containing carbonaceous materials in a two stage combustion process wherein sulfur and nitrogen containing carbonaceous materials and sulfur fixation agent particulates are introduced into a first combustion stage single fluidized bed having a density/size selective solids withdrawal conduit. The carbonaceous materials are combusted in the fluidized bed under substoichiometric oxygen conditions at temperatures of about 1600.degree. to about 2000.degree. F. producing ash and reducing gases forming a reducing region in a major portion of the single fluidized bed, the reducing gases comprising gaseous sulfur compounds. In a reducing region of the fluidized bed, the gaseous sulfur compounds are reacted with oxides of the sulfur fixation agent forming an intermediate solid metallic sulfur compound and nitrogen contained in the carbonaceous materials is converted to molecular nitrogen. The intermediate sulfur compound is reacted in an oxidizing region maintained at a base portion of the fluidized bed to form a stable, solid, environmentally acceptable sulfur containing compound which is withdrawn through the selective solids withdrawal conduit with agglomerated ash.

    摘要: A process and apparatus for oxygen-rich combustion wherein a first portion of about 5 to about 40 percent of the total fuel to be cracked and combusted is introduced to a cracking chamber where it is combusted and cracked at a temperature below about 2200.degree. C. to produce a cracked products mixture. Oxygen-rich gas of greater than about 30 volume percent oxygen is introduced to the cracking chamber in about 5 to about 50 percent of the stoichiometric requirement for complete combustion of the first portion of fuel introduced to that chamber. Cracked products mixture, a second remaining portion of fresh fuel and oxidizer having sufficient oxygen for substantially complete combustion of the combustible portion of the cracked products mixture and the fresh fuel is introduced to a combustion chamber wherein the combustible portion of the cracked products mixture and the fresh fuel is combusted. The process and apparatus provide a controllable, highly luminous, high temperature and high kinetic energy flame in the combustion chamber resulting in enhanced heat transfer rate to the furnace load, increased furnace specific production rate, increased furnace thermal efficiency, and reduced nitrogen oxides pollutant emissions.

    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.
