一、概述 当前全世界生产的金属铜约有85％是由火法产出的,而其中大部分又是由反射炉产出的,所以反射炉至今在铜冶炼中占有重要地位。但是反射炉有其固有的缺点:熔炼过程所需热量的70％依靠燃料燃烧来供给,故燃料消耗量大;热效率低;烟气量大,SO_2浓度低,难以回收利用,放空又会造成公害,等等。 I. Overview At present, about 85% of the world’s copper metal is produced by the fire method, and most of them are produced by the reverberatory furnace. Therefore, the reverberatory furnace occupies an important position in the copper smelting. However, the reverberatory furnace has its inherent drawbacks: 70% of the heat required for the smelting process is supplied by the fuel combustion, so the fuel consumption is large; the thermal efficiency is low; the flue gas is large, the SO2 concentration is low, it is difficult to recycle, ,and many more.
