ABSTRACT:
An improved method and apparatus for by-product coke oven operation wherein the problems of pollution caused by charging, oxidation of the coke during pushing, transportation of the incandescent coke to a quenching tower and quenching of the coke is eliminated by the evacuation of the gases during charging, by quenching the coke in a closed system during the push so that the temperature of the coke leaving the guide is below its ignition point; the combustion gases created by the charging and the steam and gases generated by the quenching are extracted and cleaned in a centralized dust collection system. The coke being quenched in a sealed system to a temperature lower than its ignition point, eliminates the oxidation thereof and the efficiency of the oven is increased by being able to push in shorter schedules as the necessity for extra coking time now taken to insure that all the green coke is coked, is obviated. The instant improved method comprises reliable equipment with minimum manpower for operation and maintenance. This equipment makes possible the adoption with very minor changes to present facilities and with practically no down time for the adoption thereof. Further it makes possible the use of contaminated water which nowadays presents a major problem of disposal and also the treatment of the gases from the flues.
