鞍钢炼铁厂六高炉三座外燃马琴式热风炉上采用了套筒式陶磁燃烧器.文中介绍了该燃烧器的结构、材质与技术性能.热风炉设计风温1250～1300℃.热风炉建成后进行了冷态测定,投产后进行了工业生产试验.试验期在燃烧室与蓄热室不同高度及径向用热电偶进行测温;从燃烧室抽烟气取样进行气体分析;通过试验所得数据比较陶瓷燃烧器与金属燃烧器生产上的差异,前者燃烧能力提高70%左右.调节范围广.拱顶温度提高70℃,可使热风炉生产高温、长寿、安全,因而得出基本肯定该种陶瓷燃烧器的结论.
The structure, material and technical performance of this burner are introduced in this paper.The design temperature of hot blast stove is 1250 ~ 1300 ℃ .The hot blast After the completion of the furnace, the cold state was measured and the industrial production test was carried out after it was put into production.The temperature was measured by thermocouples at different heights and radial directions of the combustion chamber and the regenerator during the test period, and the gas was sampled from the combustion chamber by gas sampling. The obtained data compare the difference between the production of ceramic burner and metal burner, the former combustion capacity increased by about 70% .Adjustment of a wide range.Var temperature increase of 70 ℃, can make hot blast stove production of high temperature, long life, safety, and thus reached the basic positive The conclusion of this kind of ceramic burner.
