日产1600t／d氧化铝循环流态化焙烧 摘要 当今世界成功地应用于工业生产的流态化焙烧炉有三种，原西德鲁奇公司的循环流态焙(C．F．C). 美国铝业公司的流态闪速焙烧炉(F．F．C)。丹麦史密斯公司的气体悬浮焙烧炉(G．s．c)。对于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。并指出了引进应以流态化闪速焙烧炉优先，消化创新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。 关键词：闪速流态化焙烧 循环流态化焙烧 焙烧炉 氢氧化铝 Cycling fluidiztion calcinations calciner of producing alumminum oxide 1600t/d Abstract In todays world successfully applied to industrial production for the three fluidized roaster, the company Xideluqi the cycle of flow-baking (CFC). Alcoa pattern flash roaster (FFC). Denmark Smiths suspension of gas roaster (Gsc). In this paper three kinds of fluidization calciners, which have widely used in alumina production , are analyzed and compared . And their characteristics and shortcoming are pointed out .The author thinks that fluidzation 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. Finally, Chinas aluminum industry should be suspended gas roaster based in the digestion and absorption fluidization technology roasting under the premise of the development of innovative form suitable for the characteristics of Chinas alumina industry fluidization roaster.
