气化型煤在有色金属冶炼中的应用研究

Coal gasification type application research in smelting non-ferrous metal

我国是世界上的主要产煤大国,有着丰富的煤炭资源。然而,近些年来,由于我国采煤技术机械化的普遍应用,煤矿开采出来的原煤中粉煤比例不断攀升,块煤的出产率却逐渐下降,导致粉煤产量过剩,块煤市场紧缺。将粉煤加工成气化型煤,一方面缓解了块煤市场供应不求的现状,也在一定程度上减轻了粉煤利用过程中产生的污染。将气化型煤应用在有色金属冶炼中,既节约了工业生产成本,又避免了环境过度污染,粉煤大量积压。因此,对气化型煤在有色金属冶炼中的应用研究有着重要意义。

Our country is the main coal-producing countries in the world, and has abundant coal resources. In recent years, however, due to the widespread application of mechanized coal mining technology in China, coal mined in the raw coal pulverized coal proportion rising, fruit of lump coal rate is declining. A shortage of excess pulverized coal output, coal market. Type to turn pulverized coal gasification of coal, on the one hand, ease the lump coal supply for the status quo, and to a certain extent, reduce the pollution occurring in the process of pulverized coal utilization. Applying type gasification of coal in non-ferrous metal smelting, the industrial production cost is saved, and avoids excessive pollution environment, pulverized coal a large backlog. Therefore, the type of gasification of coal in the application of the smelting non-ferrous metal research has important significance.
