摘要： A burner and method is disclosed in which a first oxidizing gas containing a high oxygen concentration is injected as a stream into the central zone of combustion tunnel, and part of the fuel is injected into said central pyrolysis zone to mix with said first oxidizing gas to create a highly luminous, high temperature flame core containing microparticles of carbon of the proper size for maximum luminosity and high temperature, and a relatively small amount of hydrocarbon radicals. In addition, the remaining part of the fuel is injected in a plurality of streams about said flame core to mix with a second oxidizing gas containing a lower oxygen concentration than the first oxidizing gas and injecting said second oxidizing mixture about said flame core and said remaining fuel flow to mix with said remaining fuel flow. This creates a plurality of fuel lean flames which are directed toward said luminous flame core to form a final flame pattern having high temperature, high luminosity and low NO.sub.x content.

摘要： A charge is admitted into a shaft furnace so as to form a charge column therein. The lower end of the column is melted with a flame and the charge moves downwardly by gravity as melting proceeds. The flame is generated by admitting one or more streams of oxygen and one or more streams of fuel into the furnace. A stream of oxygen and a stream of fuel are admitted into the furnace as a pair and in such a manner that the respective oxygen stream is surrounded by the respective fuel stream. This procedure provides the result that the fuel entering the furnace withdraws so much heat from the surroundings that water-cooling of the burners may be eliminated. Moreover, the withdrawal of heat from the surroundings serves to cool the furnace wall in the regions of the burners sufficiently for molten material flowing on the furnace wall in these regions to solidify. Consequently, protuberances are formed on the furnace wall. The charge column is supported on these protuberances which provides the advantage that the charge column does not contact the molten material at the bottom of the furnace. In addition to this effect, the protuberances serve to protect the furnace lining by forming a thermal shield therefor. The size of the protuberances can be controlled by partially pre-mixing the oxygen and the fuel and by regulating the rate of expansion and flow rate of the oxygen and fuel. In order to permit the oxygen and fuel to be admitted into the furnace in the manner outlined, the burner or burners may be constructed with plural openings which are arranged such that the opening through which the oxygen enters the furnace is at least partially surrounded by the opening or openings through which the fuel enters the furnace. One embodiment contemplates an annular burner having a central slit for the admission of oxygen into the furnace and two slits for fuel which flank the oxygen slit. Another embodiment contemplates a plurality of individual burners which are constructed in the form of double-walled conduits.

摘要： A burner chamber with a flat top is provided with an hexagonal array of specifically spaced apertures through which are discharged free turbulent jets into a mixing chamber in which the fuel gas is mixed by entraining heated air. Combustion occurs above the plane where the jets coalesce and a ceramic top is provided on top of the combustion chamber for heating by combustion products. These hot jets are brought in heat exchange relationship with air flowing into the mixing chamber; radiation from the ceramic top heats the burner chamber.

摘要： The quench chamber of a slagging pressure gasifier is provided with a perforated tubular air ring remote from the slag tap main burner of the gasifier and arranged, in use, to supply the burner with a secondary air supply and, at the same time, to set up an air circulation adjacent the walls of the chamber above the normal water level therein, thereby to cool the walls. There is further provided a nozzle mixing ring burner for use in a slagging gasifier comprising a body having two integrally formed chambers each having respectively a gas inlet and outlet and an air/oxygen inlet and outlet. The outlets are directed toward a shaped annular portion on the inner periphery of the ring body.

摘要： A burner for heating an airstream is disposed in the airstream and has four identical walls which are secured together along their sides to form a tapered combustion chamber, the small end of which is located upstream. An axially extending gas pipe opens into the small upstream end of the combustion chamber and through this pipe a combustible gas enters the combustion chamber. Combustion air from the airstream enters the tapered chamber through apertures in the walls and the mixture so formed is ignited, resulting in a self-sustaining flame. A flame probe, which extends through the axial supply pipe and into the combustion chamber for a substantial distance, senses the flame regardless of whether it is high or low. The combustion chamber walls bulge inwardly intermediate there sides to insure that the combustion air reaches the center of the combustion chamber and mixes thoroughly with the combustible gas. A shroud surrounds the combustion chamber walls and has a metering inlet which opens upstream. The interior of the shroud is pressurized with air from the airstream, and this air enters the combustion chamber through the apertures in the walls thereof.

摘要： A furnace has a self-recuperative burner mounted in a port in a wall of the furnace so as to form a products passage to conduct products of combustion from the furnace chamber to outside the furnace. The burner includes an air passage which leads to a nozzle mounted in the inlet of a combustion chamber and which is in heat-exchange relationship with the products passage. The air passage extends at first forwards beyond the inlet of the combustion chamber and then rearwards to the nozzle so that the air-heating surface area is more effective and metal in the hottest part of the products passage is cooled.
