From the perspective of improving coke quality, is it better to raise the furnace temperature or lower it?
It’s better to raise the temperature. But it should not be too high
Heating regime for coking: The main factors affecting the heating regime in coking are the heating rate and the temperature at the end of coking. Increasing the coking rate can enhance the fluidity of the colloids, resulting in coke with better strength. However, accelerating the coking rate also increases the cracks in the coke and reduces its lump size. Increasing the temperature at the late stage of coking can improve the wear resistance of coke, but it reduces its lump size. Since the ultimate shrinkage of coke increases, cracks in the coke inevitably increase as well, causing the coke to crack along these cracks. Therefore, it is necessary to determine a reasonable coking heating regime to give the coke greater wear resistance and bulk density.
