Abstract: A dry quenching apparatus for hot coke has an upright housing having openings for charging and discharging the coke. An annular header for exhausting gases from the quenching zone is arranged in the middle portion of the housing. In the lower portion of the housing there is an annular header for supplying a cooling agent and communicating through corresponding passages with a distributor disposed above the annular header for supplying a cooling agent and centrally of the housing. An annular distribution header is arranged above the annular header for supplying a cooling agent and has vertical partition walls dividing the distribution header into sections. Each section has at least one opening through which the annular header for supplying gases and the annular distribution header communicate. At least one opening in each section accommodates a flow governor for a cooling agent.
