Abstract:

The proper and process equipment of CDQ are improved and optimized by increasing the volume of prechamber,adopting double flue technology,improving the performance of refractories,optimizing the charging device,modifying the secondary de-duster and optimizing the crane system.After improvement,the temperature of discharged coke is reduced to 140℃,the utilization rate of waste heat is increased,and coke supply to the blast furnace can be ensured.
