Patent ID: 7998316

Claim:
A method for quenching metallurgical coke made in a coking oven, the method comprising the steps of: pushing a unitary slab of incandescent coke onto a substantially planar receiving surface of an enclosed quenching car so that substantially all of the coke from the coking oven is pushed as a unitary slab onto the receiving surface of the quenching car; quenching the slab of incandescent coke in an enclosed, gas tight environment within the quenching car, the quenching step including: spraying quench water on at least a portion of the slab of hot coke with a plurality of water quench nozzles, and raising a water level in a water quenching sump disposed below the receiving surface of the quenching car for submerging at least a portion of the slab of hot coke by displacing water in the quenching sump; and subsequent to the quenching step, tilting the planar receiving surface to an angle sufficient to slide the quenched coke off of the planar receiving surface and onto a product collection conveyer and sufficient to drain water from the quenched coke.
