摘　　要：针对铝熔炼炉使用中存在气耗高、铝液金属损耗大、生产效率不高等问题,采用先进的弥散式蓄热燃烧技术取代原有的换向式蓄热式燃烧方式,系统地对铝熔炼炉进行节能升级改造,使天然气单耗降低15 m3/t·Al,铝液金属损减少2.65 kg/t·Al,降低NOx排放量,取得了良好的经济和社会效益。In operation of aluminum melting furnace,it has problems that high gas consumption,high consumption of molten aluminum and low production efficiency,the advanced dispersion regenerative combustion technology was used to instead of the original commutation regenerative combustion method,the energy saving upgrading and reconstruction of aluminum melting furnace can be carried systematically,then the unit consumption of natural gas was decreased by 15 m3/t·Al,Metal loss of molten alumnium was decreased by 2.65 kg/t·Al,the discharge amount of NOx was decreased,good economic and social benefits can be got.
