In shaft kiln technology, the coke flows by gravity through multiple vertical shafts with flue wall surrounding it. Residence time is longer compared with rotary kiln (24–36 hours for shaft vs. < 1 hour for rotary kilns), resulting in slower heat up time. Shaft kilns have an advantage when processing coke containing high quantity of fines and high VCM.
