A ROTARY KILN is a Direct Fired, Refractory Lined equipment for high temperature applications where it is necessary to change the 'state' of the material in a continuous process or in batch type process. Since this process usually requires a long residence time, the length to diameter ratio is often in excess of 10:1 in a continuous kiln.
In a "Shaft calciner" green coke is filled on top into individual shafts and flows by gravity through these shafts in 24 to 36 hours, resulting in a heat up rate of ~1°C per minute (compared to 50°C in a rotary kiln). Thanks to this very slow heatup rate, green coke with high VCM (12 .
