本钢3号高炉始建1941年,炉容758m~3,1956年～1972年炉容为917m~3,1972年改造成1070m~3至今。热风炉为了适应扩容后的高炉,也不断的加高,为了增加蓄热面积,由原来的32m高提高到38.354m,1980年又加高到43.217m 一、热风炉改造设计 1.热风炉内燃改外燃的必要性随着高炉的不断发展,特别是为了改善喷吹燃料的效果,以进一步降低焦比,要求热风炉提供的风温越来越高,而燃烧室位于热风炉内一侧的内燃式热风炉,当风温长期维持在1000℃左右时,内部结构就要发生破坏,限制了风温进一步提高。
Bengang No.3 blast furnace was first built in 1941, with a capacity of 758m ~ 3. From 1956 to 1972, the furnace capacity was 917m ~ 3, and from 1972 to 1070m ~ 3 so far. In order to adapt to the blast furnace expansion, but also continuously increased, in order to increase the regenerative area, from the original 32m high to 38.354m, in 1980 and increased to 43.217m First, the design of hot stove 1. Hot stove internal combustion The need to change the external combustion With the continuous development of the blast furnace, especially in order to improve the effect of blowing fuel, to further reduce the coke ratio, requiring hot air stove to provide higher and higher temperature, and the combustion chamber is located inside the hot stove side Of the internal combustion stove, when the wind temperature is maintained at about 1000 ℃, the internal structure will be destroyed, limiting the further increase in temperature.
