平焰烧嘴和传统的烧嘴不同,它喷出的不是直焰而是贴着炉壁向四周均匀伸展的圆盘形薄层,它具有升温快、温度均匀、节约燃料和可按钢种和产量灵活供热等优点。在各种加热炉的改造中已获得了广泛的应用。在选用平焰烧嘴设计和改造加热炉时,应根据平焰烧嘴的特点,采取一些相应的措施,才能收到较好的经济效果。本文结合我厂辊底式钢管热处理炉等应用平焰烧嘴的实践经验,对平焰烧嘴应用中的几个技术问题进行了探讨。
Flat flame burner and traditional burner is different, it is not sprayed out of the flame but the furnace wall is evenly extended to the surrounding disc-shaped thin layer, it has a fast warming, uniform temperature, saving fuel and can be steel And yield flexible heating and other advantages. In a variety of furnace transformation has been widely used. In the selection of flames burner design and transformation of the furnace, should be based on the characteristics of flames burner, to take some appropriate measures to receive better economic results. Based on the practical experience of flat flame burners, such as the roller hearth heat treatment furnace in our factory, several technical problems in the application of flat flame burners are discussed in this paper.
