本文报道的新型燃烧器是一种适合于顶燃式热风炉的短焰燃烧器。这种燃烧器可以解决国内现有的顶燃式热风炉——第一代顶燃式热风炉存在的燃烧口附近炉皮发红、高温区开大孔或多开孔、火焰不够短等问题,从而减少维修量和延长热风炉寿命。这种燃烧器的研制成功将使顶燃式热风炉进入一个新阶段——第二代顶燃式热风炉;为考贝式热风炉的改造闯出了一条新路子。实验是在热模型上进行的。实验表明,这种燃烧器结构简单、燃烧性能良好、火焰短、达到了预期效果。
The new type of burner reported in this paper is a short-flame burner suitable for a top-firing hot blast stove. This kind of burner can solve the problems of the existing top-burning type hot-blast stove in China, such as the burned-out skin near the combustion mouth of the first-generation top-burning hot blast stove, the opening of large holes or holes in the high temperature zone and the short of flame , Thereby reducing the amount of maintenance and prolong the stove life. The successful development of such burners will bring the top-burning stove into a new stage - the second generation of top-burning stoves and break new ground for the renovation of the Kao Bei stoves. Experiments were conducted on the thermal model. Experiments show that the burner has the advantages of simple structure, good combustion performance and short flame, which achieves the expected effect.
