摘　　要：有色金属冶炼产业的规模化、集约化、智能化发展,推动了现有流态化焙烧炉技术向大型化、高效化、智能化发展。本文介绍了大型流态化焙烧炉的工艺特点及结构参数,针对早期109 m^(2)流态化焙烧炉存在的变形、冒烟和漏风问题,后期开发的152 m^(2)流态化焙烧炉在工艺参数和炉体结构方面进行了优化,并采用了整体浇注技术。实践证明,152 m^(2)流态化焙烧炉炉况稳定、操作简便、技术指标先进。未来的流态化焙烧炉将进一步朝着高效率、低污染、智能化的方向发展。The large-scale,intensive,and intelligent development of the non-ferrous metal smelting industry has promoted the development of the fluidized roaster technology to large-scale,high-efficiency,and intelligent development. This article introduces the technological characteristics and structural parameters of a large-scale fluidized roasting furnace. In view of the deformation,smoke and air leakage problems of the early 109 m^(2) fluidized roasting furnace,the 152 m^(2) fluidized roasting furnace developed in the later stage has been optimized in terms of process parameters and furnace body structure,and adopts integral casting technology. Practice has proved that the 152 m^(2) fluidized roasting furnace has stable running conditions,simple operation and advanced technical indicators. The future fluidized roasting furnace will further develop in the direction of high efficiency,low pollution and intelligence.
