烟气在炉内的流动情况如何,对炉内的温度分布,物料的加热质量均有很大影响。本文针对某厂所提出利用新型高速燃烧器代替传统的普通烧嘴改造台车式热处理炉,进行了以空气为介质的等温模型试验;确定了燃烧器的布置和炉型结构,给炉子的改造设计和生产试验提供了有价值的参考资料。 Flue gas flow in the furnace how the temperature distribution of the furnace, the heating quality of materials have a great impact. In this paper, a factory was proposed to use a new type of high-speed burner to replace the traditional ordinary burner to transform the car-type heat treatment furnace, the air as a medium isothermal model test; to determine the burner layout and furnace structure, to the furnace transformation Design and production tests provide valuable references.
