【摘要】 对广泛应用于氧化铝工业生产的三种流态化焙烧炉进行了分析和比较,指出了三种炉型各自的特点和不足。流态闪速焙烧炉和循环流态焙烧炉技术经验成熟,生产稳定性较强,气体悬浮焙烧炉能耗指标先进。并提出了引进应以流态化闪速焙烧炉优先,消化创新应以气体悬浮焙烧炉为基础。最后指出我国铝工业应以气体悬浮焙烧炉为基础,在消化吸收流态化焙烧技术的前提下发展创新,形成适合我国氧化铝工业特点的流态化焙烧炉。更多还原

【Abstract】 In this paper three kinds of fluidization calciners, which have widely used in alumina production, are analyzed and compared. And their characteristics and shortcomings are pointed out. The author thinks that fluidization flash calciner and circulation fluidization calciner have ripe experience and stable production, but gas suspension calciner has advanced index for energy consumption. The author also puts forward that import should give priority to fluidization flash calciner and innovation should base on gas suspension calciner. At last the author points out that on the basis of gas suspension calciner the aluminum industry in China should digest and absorb fluidization calcinations technology in order to form fluidization calciner suitable for the alumina industry in China.更多还原
