荷兰霍戈文艾莫伊登钢铁公司有一套1982～1983年建造的阿姆科型喷煤系统。该系统自投入使用以来一直运转正常,没有发生大的停工事故。该系统有一磨碎设备,包括2台碎煤机,为6号和7号高炉供煤。该系统大部分时间喷吹高挥发性煤,其置换比符合理论值,平均为0.93kg焦(87.5％C)/kg煤。 1988年碎煤机能力从30t/h增加到50t/h,因而吨铁喷煤量从100kg增加到140kg。 1991年初7号高炉4星期喷煤量达210kg/t铁。在此期间,焦耗量下降到291kg/t铁,其
Hooghoven, the Netherlands, has a set of Amco-type coal injection systems built between 1982 and 1983. The system has been operating normally since it was put into operation without major downtime. The system has a grinding equipment, including 2 crusher, for the 6 and 7 blast furnace for coal. The system injects highly volatile coal most of the time, with a replacement ratio that meets the theoretical value, averaging 0.93 kg coke (87.5% C) / kg coal. In 1988 crusher capacity increased from 30t / h to 50t / h, so the amount of iron per ton of iron increased from 100kg to 140kg. At the beginning of 1991, the blast furnace burned 210kg / t iron for 4 weeks. During this period, the coke consumption dropped to 291kg / t iron, which
