摘要：Process and apparatus for wet-quenching of hot-coke unloaded from a cokeproducing oven use water quenching from exclusive overhead tanks in two distinctconsecutive phases so as to minimize the wasteful coke-dust generated and so as to limitthe final maximum-water content in the produced coke. A high rate of water flow undercontrolled pressure head is used for a short period of time in the initial phase whereincoke- dust particles generated and rising in the water vapor cloud are washed down andprevented from entering the quenching hood; in a second and final stage, a low rate ofwater flow is maintained for a longer period of time wherein owing to the hot surface ofcoke having been already cooled in the first phase, coke-dust is not generated as much,and, the required limits for final water content can easily be maintained. Water supply isdrawn from (two) overhead tanks ensuring constant head, and using rapid closing valvesin conjunction with an electrically controlled valve and two separate sets of water jets forthe two quenching phases respectively.
