Abstract: Coal not normally used for coking is, prior to feeding to coking batteries, processed in a vertical suspension preheater heated by combustion gases from the coking batteries; the coal particles are separated from these combustion gases in two alternately operating sets of primary and secondary cyclone separators and are then supplied to coking batteries together with part of the combustion gases which serve as carrier gases for the coal particles.
