Abstract
Abstract A coke quench car having a slanted bottom and discharge opening in one wall is provided with a movable grate at the discharge opening to drain water and retain coke. A door outboard of the grate closes the discharge opening in a substantially liquid-tight condition and accumulates quench water in the car to submerge the coke. Means are provided for selectively opening the door to drain only water at the quench station and for later opening the grate to discharge the quenched coke at the coke wharf. A second embodiment provides a tilting bottom coke car with a first sealing means for sealing the car in substantially liquid-tight condition to accumulate water and submerge the coke. A second sealing means are provided to permit the floor to be tilted to a liquid discharge position to drain only water. Means are provided for tilting the floor between an open and closed and intermediate liquid discharge position.
