Patent ·
OSTI ID:5544423
; ;
Disclosed are methods for drying coking coals to be charged in coke ovens utilizing a heating medium which recovers the sensible heat contained in the gas generated in the coke ovens as a heating source for drying coking coals to a desired moisture content. Chiefly based on the moisture of coking coals before drying, the flow rate of the heat medium to the coke dryer is controlled or a hot blast generated in a separate heating system is used for the drying.
