ABSTRACT:
Heated bulk material, such as coke, is quenched by a liquid flowing from the top downwardly through the bulk material. During the quenching the bulk material is closed off from the atmosphere. The steam forming from the quenching liquid is carried off downwardly in parallel flow with the quenching liquid. For this purpose the amount of quenching liquid distributed over the bulk material is so measured or dosed that it participates completely in the quenching process, whereby the quenching liquid evaporates completely except for a specific residual moisture in the coke. The flow resistance which varies over the base surface of the bulk material is compensated by a carry-off resistance which is inversely proportional to the respective bulk material height. The varying of the flow resistance is due to a bulk material height which changes from one side of the quenching container to the opposite side as a result of an inclined container bottom. Additionally, the amount of quenching liquid distributed over the top surface of the bulk material is substantially proportional to the respective height of the bulk material. The quenching chamber is provided with an inclined, perforated bottom. The perforations are so dimensioned that the ratio of bulk material height to the respective open passage area of the bottom is approximately constant.
