摘　　要：应用计算流体学(CFD)结合工程实践,对干熄焦工段内焦炭烧损现象发生的部位及速率进行研究。通过计算可获得干熄焦工段内各碳溶反应(C-H_(2)O、C-C O_(2)、C-O_(2))速率分布云图、焦炭烧损率及各粒级焦炭烧损所占比例,这可为合理确定干熄焦生产过程中焦炭烧损率控制指标提供有益参考。Based on project experience,Computational Fluid Dynamics(CFD)is applied to study the position and rate of coke burning occurred in CDQ unit.Through computation,the contours of carbon solution loss reaction(C-H_(2)O,C-CO_(2),C-O_(2)),coke burning loss rate and the ratio of burning loss of coke with different coke size to total burning loss,which can be utilized as a reference for reasonably determining the targets of coke burning loss in CDQ production.
