Abstract: A process for quenching hot coke discharged from an oven of a battery of coke ovens into a one-spot car. The process utilizes a unique arrangement of two sets of narrow angle spray nozzles to quench the coke. In addition to quenching the coke, one set of spray nozzles initially knocks down the peak portion of the coke pile and distributes the coke so that the exposed surface of the coke is substantially level. The quench liquid discharged through the narrow angle spray nozzles contacts about 50% to about 70% of the substantially level, exposed surface of the hot coke. Sufficient openings are provided adjacent the bottom of the one-spot car to drain the quench liquid to prevent the buildup of quench liquid in the quench car.
