内燃式热风炉(以下简称热风炉)拱顶长期处于高温状态下工作。它不仅需要采用与高温相适瘟的性能良好的耐火材料,还需要具有足够稳定性的砌体结构。由于高炉鼓风温度的不断提高,在生产实践中,传统的考贝式热风炉半球拱顶暴露出一些缺陷。例如:拱顶开裂;蓄热室气流分布不均而出现“锅底”;燃烧室上方气流反射面高度不足而引起脉动燃烧等。为了提高热风炉的传热 Internal combustion hot stove (hereinafter referred to as hot stove) long vault at high temperature work. Not only does it require the use of well-behaved refractory materials that are compatible with high temperatures, but also masonry structures with adequate stability. As blast furnace blast temperature continues to increase, in the production practice, the traditional test-style stove Hemisphere dome exposed some flaws. For example: vault cracking; uneven distribution of regenerator air flow and the emergence of “bottom of the pot”; above the combustion chamber air flow reflector surface height caused by inadequate pulsating combustion. In order to improve the heat transfer stove
