摘　　要：对罐式炉和回转窑这两种煅烧处理方式从煅烧工艺技术、煅烧质量、工程建设环境及主要技术经济指标等方面综合比较,以便寻求相对合理的方案,并寻求两种煅烧方式今后努力的方向。文中指出:两种煅烧处理方式在煅烧工艺原理、实收率、产能、煅烧质量、能耗及运行费用等方面存在着较大的区别,尤其是在煅烧质量与铝用阳极消耗密切相关的煅烧焦真密度、电阻率、空气反应性、CO2反应性等几个方面存在着较大的差异;基于目前生石油焦质量与供应等情况,采用罐式炉工艺生产铝用阳极焦相对具备竞争优势;无论对罐式炉还是回转窑均需进一步优化设计与工艺操作。At present,the petroleum coke is mainly calcined by vertical shaft furnace or rotary kiln to meet the requirement of prebaked anode used for aluminium reduction in China.Vertical shaft furnace for calcination is quite different from rotary kiln for calcination in the principle of calcination process,calcined coke quality,product availability,production capacity,energy consumption,operation cost,and environmental issues and especially in the properties of calcined coke on real density,air reactivity,and CO2 reactivity which are closely related to the consumption of anode in aluminium reduction.Therefore,calcination of coke used for aluminium reduction by vertical shaft furnace is more competitive based on the existing quality of the delayed coke and supply thereof.
