经试验室研究及扩大试验,最新开发的ACL顶燃式热风炉于1987年3月在湖南冷水江铁焦总厂进行工业性试验研究,并取得了此项新技术新工艺推广应用的重要数据,4个多月的工业试验表明:只使用高炉煤气,拱顶温度最高达1375℃,平均1267℃,出口风温最高达1320℃,平均1220℃,短焰燃烧器燃烧稳定,空气过剩系数1.02~1.05;热风炉结构合理,径向温度分布均匀,消除了一般顶燃热风炉的结构缺陷。该热风炉操作与传统热风炉相同,安全可靠;每1m~2加热面积投资比改造内燃式热风炉高4%,但热效率高,获得的风温高,经济效益大,对老厂改造或新厂建设均有推广使用的价值。
The laboratory research and expansion of the test, the newly developed ACL top-burning stove in March 1987 in Hunan Lengshuijiang coke plant industrial pilot study and made the promotion of this new technology and application of important data More than four months of industrial tests show that blast furnace gas can reach temperatures of up to 1375 ° C with an average of 1267 ° C and an outlet temperature of up to 1320 ° C with an average of 1220 ° C. The short-burners have a stable combustion with an air excess coefficient of 1.02 ~ 1.05; The structure of the hot blast stove is reasonable and the radial temperature distribution is even, eliminating the structural defects of the general top burning hot blast stove. The operation of the hot stove is the same as that of the traditional hot stove, and the investment per heating area of 1m ~ 2 is 4% higher than that of the reformed internal combustion stove, but the heat efficiency is high, the temperature is high and the economic benefits are great. Plant construction has the value of promoting the use.
