结合公司第一小型轧钢厂蓄热式烧嘴加热炉中修改造项目,介绍了蓄热式烧嘴加热炉的概况、燃烧系统的结构特点。加热炉最初采用完全分散换向方式,存在一些问题:换向阀质量、排烟温度过高、炉膛压力过高等。针对上述问题产生原因进行了分析,提出了解决办法,采用多段分散式控制布置,在增产降耗、高效节能上具有明显的优势。
With the company’s first small-scale rolling mill regenerative burner heating furnace repair projects, introduced the overview of regenerative burner furnace, combustion system structural characteristics. Furnace initially fully dispersed commutation method, there are some problems: the quality of the valve, exhaust gas temperature is too high, the furnace pressure is too high. In view of the causes of the above problems are analyzed, the solution is proposed, the use of multi-stage distributed control arrangement, in the increase of production and consumption, high efficiency and energy saving has obvious advantages.
