The invention relates to a furnace combustion structure having the function of oxygen-supporting combustion, which comprises a combustion nozzle, a combustion supporting air nozzle and a furnace body space, wherein the combustion supporting air nozzle is composed of an upper skew arch above, a lower bottom plate and sidewalls at two sides, the combustion nozzle which is disposed below the combustion supporting air nozzle is provided with 3 horn-shaped oxygen-supporting combustion nozzles (combustor flame is transversely distributed) and is 0.5 to 1 meter away from the furnace body space, and an included angle of 14 degrees is formed between the combustion supporting air nozzle and the combustion nozzle. When a furnace having this structure is in used, fuel is mixed with low-temperature combustion supporting air entering from a heat accumulation chamber so as to result in a carbon separation process and then enters into the high-temperature furnace body for combustion. The structure can improve the uniformity of temperature field in the furnace, enhance the radiation coefficient of fuel-combusting flame and the production quality of metallurgical accessories, and intensify the heat exchange capability of combustion flame and metallurgical accessories, thus fuel consumption, pollutant emission and production cost of metallurgical accessories are all reduced.
Description
Technical field [0001] The invention relates to a kiln combustion structure with oxygen-assisted combustion, in particular to a kiln combustion structure belonging to the technical field of heat storage combustion and mainly used in a metallurgical auxiliary material heating system of a horizontal flame metallurgical auxiliary material pool kiln. Background technique [0002] Metallurgical auxiliary materials are necessary raw materials for the production of high-quality steel products. High-quality metallurgical auxiliary materials can improve the quality of steel products, but the production of high-quality metallurgical auxiliary materials must rely on kilns with excellent performance. The temperature field inside the kiln is decisive for the production of metallurgical auxiliary materials. At the same time, the kiln is currently the second largest energy-consuming industry after the boiler. How to improve the combustion performance of fuel has become a frontier issue in ...
