本文通过对反烧炉的实际燃烧过程的分析和上点燃煤饼的燃烧试验证明,上点燃煤炉的燃烧过程分为两个阶段:一是挥发物从上而下的燃烧;二是焦炭从下而上的燃烧.此外,为实现煤饼的上点燃,还提出了设置二次风和聚热罩等改进炉子结构的措施. In this paper, through the analysis of the actual combustion process of the anti-burning furnace and the burning test on the ignited coal cake, the combustion process of the upper burning coal-fired furnace is divided into two stages: first, the combustion of volatile matter from the top to the bottom; Coke combustion from the bottom up.In addition, in order to achieve the lit coal briquette, but also set up the secondary air and heat shield and other measures to improve the structure of the furnace.
