我厂四座100立方米高炉生产,其中两座冶炼锰铁。每天产高炉煤气160多万立方米,除热风炉自用约一半外,其余排放大气,相当于每年浪费4.2万吨标准煤,既浪费能源,又污染市区环境。为此,七十年代初改造煤气清洗系统,大部分高炉煤气得到清洗;七十年代中期,用剩余煤气试烧2吨锅炉取得经验,提出将全部高炉剩余煤气用于烧2台20吨锅炉的回收利用高炉煤气工程设 I plant four 100 cubic meters blast furnace production, of which two smelting ferromanganese. Every day, more than 1.6 million cubic meters of blast furnace gas is produced. Except for about half of blast furnace gas used for self-use, the rest discharges the atmosphere, equivalent to 42,000 tons of standard coal wasted each year, which is waste of energy and pollutes the urban environment. To this end, the early seventies transformation of gas cleaning system, most of the blast furnace gas to be cleaned; the mid-seventies, the remaining gas trial burning 2 tons of boilers gain experience, put forward the remaining blast furnace gas used to burn two 20-ton boiler Recycling blast furnace gas project
