Abstract:

The influence of CDQ chamber level,gas coke ratio,circulating air flow and material stay time to the average grain size of coke before and after change of CDQ operation mode was studied.Countermeasures were taken to optimize the production.After optimization,the coke grain size was stable and improved,and gas yield was increased,while power consumption was reduced.
