现代铁矿球团厂的燃料消耗已经降低到这种程度,即预计将来只能有少量节省。鉴于重油和天然气的价格高,在许多厂用煤代替这些燃料可以降低生产成本。现有球团厂通过往铁矿原料中加煤以及用煤粉焙烧球团矿,可以代替部分重油和煤气。己经为鲁奇—德腊沃带式焙烧机工艺设计出两套可以完全用煤代替重油或煤气的系统。介绍了以煤作为铁矿球团厂燃料的各种工艺,特别是最近设计的鲁奇多段喷煤与燃烧(LMC)工艺,可以使用多种多样的铁矿石和煤,甚至可以使用灰分很高的煤。 Modern iron ore pellet plant fuel consumption has been reduced to this extent, that is expected to have only a small amount of savings in the future. In view of the high price of heavy oil and natural gas, the substitution of these fuels for many plant coal can reduce production costs. The existing pellet plant by adding iron ore to raw materials and pulverized coal pellets can replace part of the heavy oil and gas. Two systems that completely replace coal with heavy oil or gas have been devised for the Lugo-Della Rover belt roasting process. The various processes using coal as iron ore pellet plant fuel are introduced, especially the recently designed Lurgi multistage coal injection and combustion (LMC) process, which can use a variety of iron ore and coal, and even high ash content Coal
