Bauer, E G

A method is described of controlling the crossflow of gases given off by a coal mass during the production of coke in a coke oven having a coke side collector main and a pusher side collector main comprising the steps of: (a) determining the temperature difference between the temperature in the coke side standpipe and the temperature in the pusher side standpipe, (b) determining the temperature difference between the temperature in the freespace adjacent the coke side of the coke oven and the temperature in the freespace adjacent the pusher side of the coke oven, (c) determining the temperature difference between the temperature of the heating wall of the coke oven adjacent the coke side of the coke oven and the temperature of the heating wall of the coke oven adjacent the pusher side of the coke oven, and (d) opening the coke side standpipe control valve and gooseneck damper and the pusher side standpipe control valve and gooseneck damper, if they are not in the open position, if the temperature difference of step (b) is substantially the same as the temperature difference of step (c) and the temperature difference of step (a) is greater than about 50/sup 0/F in order to control crossflow.
