TITLE OF THE INVENTION: METHOD FOR QUENCHING COKE ABSTRACT OF THE DISCLOSURE: Preheated bulk material capable of coking is quenched by flowing the quenching liquid through the loose bulk ma- terial, whereby the bulk material is substantially closed off relative to the atmosphere. The liquid is applied to the top of the bulk material in a quenching chamber which is closed at its top by a sealed cover and which has an open grating for a horizontal bottom. The steam formed by the quenching liquid and, if formed, any excess quench- ing liquid are drawn off from the quenching chamber through the open grating. The total quantity of quenching liquid to be supplied as a function of time is controlled by a valve through a control signal depending on the chemical and physical properties constituting bulk material char- acteristics prior to the heating of the coal. The control signal also takes into account the type of the intended heat treatment in the form of quenching characteristics. In a surprisingly simple embodiment the valve may be con- trolled by the operation of a cam disk which has a cam sur- face shaped in accordance with these characteristics. -1-
