奥托昆普铜镍冶炼厂通过提高闪速熔炼富氧浓度来提高能源的利用率。该公司在哈里亚瓦尔塔冶炼厂旁边新建一座氧气厂,1984年9月投产。闪速熔炼富氧浓度已从30～50％增加到60～95％,燃料油消耗下降,在出炉烟气减少同时,冶炼厂生产能 Outokumpu’s copper-nickel smelters increase energy use by increasing the oxygen enrichment of flash smelters. The company built a new oxygen plant next to the Ria Valluta smelter and started production in September 1984. Flash smelting oxygen concentration has increased from 30 to 50% to 60 to 95%, fuel oil consumption decreased, the reduction in the flue gas at the same time, the smelter production capacity
