  • Automatic coke oven plant with means to insure sufficient coking
    Patent number: 4021309
    Abstract: A method and apparatus for the production of coke from coal by a dry distillation operation wherein the coking plant is provided with a computer unit that receives signals from the coal leveling mechanism, the door mechanism, the quenching car mechanism, and a signal value for the time required to achieve the coking of the coal. The computer prevents the opening of any given coking chamber until the minimum coking time has lapsed and the opening of the chamber and discharging and quenching of the coke is correlated to the actual operating conditions rushing at that time. If desired, the charging and emptying operations may be carried out on a completely automatic basis.
