据统计高炉生产在钢铁联合企业的能量消耗中约占55％,而燃料消耗约占其中的85％,由此可见需要大量的焦炭。但是能用来炼焦的煤一般只占煤储量的20～30％,因此促使人们设法对焦炭开源节流。实践表明:高风温既能节约焦炭,又能使高炉多接受喷吹燃料用来代替焦炭,还能强化高炉冶炼。热风温度每升高100℃,可降低焦比15～20公斤,增喷煤粉50公斤,或重油25公斤,使高炉能增产生铁3～4％。由于传统的内燃式热风炉存在着结构缺陷,一般风温只能达到1000～1100℃左右。西德罗斯林根厂、沙尔茨吉公司、蒂森钢铁公司分别于1959年、1963年、1965年成功地研制出地得式、柯柏式、马琴与派根司特
According to statistics, blast furnace production accounts for about 55% of the energy consumption of the steel conglomerate while fuel consumption accounts for about 85% of the total. This shows that a large amount of coke is needed. However, the amount of coal that can be used for coking generally accounts for 20-30% of the coal reserves, prompting people to find ways to reduce their income and reduce expenditure. Practice shows that: high wind temperature can save coke, but also make the blast furnace to accept more fuel injection instead of coke, but also strengthen the blast furnace smelting. Each hot air temperature increase of 100 ℃, can reduce the coke ratio of 15 to 20 kg, 50 kg of pulverized coal, or heavy oil 25 kg, the blast furnace can increase the production of iron 3 to 4%. As the traditional internal combustion stove has structural defects, the general temperature can only reach about 1000 ~ 1100 ℃. West Germany Roslingen plant, Salzgitter, Thyssen Iron and Steel Company in 1959, 1963, 1965, successfully developed the ground-based, Cooper, horse and root gangster
