Abstract (en)
[origin: US4512850A] Process and apparatus for wet-quenching of hot-coke unloaded from a coke producing oven use water quenching from exclusive overhead tanks in two distinct consecutive phases so as to minimize the wasteful coke-dust generated and so as to limit the final maximum-water content in the produced coke. A high rate of water flow under controlled pressure head is used for a short period of time in the initial phase wherein coke-dust particles generated and rising in the water vapor cloud are washed down and prevented from entering the quenching hood; in a second and final stage, a low rate of water flow is maintained for a longer period of time wherein owing to the hot surface of coke 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 is drawn from (two) overhead tanks ensuring constant head, and using rapid closing valves in conjunction with an electrically controlled valve and two separate sets of water jets for the two quenching phases respectively.
