摘　　要：在焦炉正压烘炉过程中,时而发生焦炉机焦侧管理火道的平均温度较为接近但直行温度相差较大(或两者形式相反)的现象。以某焦化厂JND55-DW型焦炉正压烘炉为例,通过理论研究焦炉炉顶区域干燥孔及水平气道的分布,并以其正压烘炉过程中的横墙温度为依据,浅析正压烘炉中热废气流入燃烧室的过程对烘炉温度管理的影响。研究发现,在焦炉正压烘炉过程中,应根据该焦炉干燥孔及水平气道的分布情况,并结合现场温度采集点的布置情况,来调控炉体机焦侧的平均温度。During positive pressure heating-up of the battery,there are occasional phenomena when the average temperature of heating flues is close between the pusher side and coke side,while the longitudinal temperature differs significantly(or vice versa).Taking the positive pressure heating-up of battery(JND55-DW type)as an example,this paper analyzes the flue gas flowing into combustion chambers and its impact on heating-up temperature management based on the study of drying hole and horizontal gas duct distribution on oven top,as well as the lateral temperature during positive pressure heating-up.Research shows that during positive pressure heating-up,the average temperature on pusher and coke side should be controlled based on the distribution of drying holes and horizontal gas ducts,and of the temperature collection points.
