炼铜阳极炉是周期性作业的精炼反射炉,全国约有30台,燃料多为重油。1981年阳极炉燃料单耗:白银冶炼厂(液态矿铜80％)为98.47kg标煤/t铜,而日本的日北厂为49.0kg标煤/t铜;阳极炉综合能耗国内最低的云南冶炼厂为92.29kg标煤/t铜,而美国为77.3kg标煤/t铜;可见差距很大。从热平衡看,热能的一半以上被烟气带走,加上炉体散热及生产组织不合理等原因导致
Copper smelting anode furnace is a cyclical operation of the refining furnace, there are about 30 units, mostly fuel heavy oil. In 1981 anode unit fuel consumption: silver smelter (liquid copper ore 80%) for the 98.47kg standard coal / t copper, Japan and Japan North plant 49.0kg standard coal / t copper; anode furnace energy consumption of the lowest Yunnan smelter 92.29kg standard coal / t copper, while the United States for the 77.3kg standard coal / t copper; shows a wide gap. From the perspective of heat balance, more than half of the thermal energy is taken away by flue gas, coupled with furnace heat dissipation and unreasonable production organization, etc.
