Abstract: The emission of solid particles during the discharging of a horizontal coking oven or furnace is substantially reduced or eliminated. For this purpose the hot air and gas convection flow which carries the solid particles substantially vertically upwardly is exposed to a shower or spray of water drops which are directed substantially horizontally into the upward convection flow. The volume, surface tension, density and speed of the water drops are coordinated relative to one another so that the water drops are loaded by taking up the solid particles whereupon the loaded drops sink down in a countercurrent flow to the upward convection flow. The solid particles carrying the water drops are removed from the convection flow by a plurality of baffles arranged in a chimney or stack in a staggered relationship so that the upward convection flow can pass through between adjacent baffles which are inclined toward respective collecting channels.

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.

Abstract: The present pressure rod for a coke discharge apparatus is constructed of hollow sectional components or tubular members interconnected with one another, whereby a lightweight structure is achieved. The hollow sectional components or tubular members are interconnected in such a manner that a coolant may flow through the structure of the pressure rod. Flexible coolant supply conduits for the inflow and outflow of coolant are connected to the hollow sectional components of the pressure rod.

Abstract: A method for clarifying coke quenching water or other waters which are contaminated by solids, with a wide grain spectrum, in an operation in which the fine portions of the solids suspended and carried along with the water are removed from the water by filtration and the clarified water is returned in a cycle, comprising, depositing the water into a filter shaft so that the substances removed from the contaminated water build up in the shaft and themselves form a filter bed, continuing to pass the water through the filter bed from the top to the bottom in a manner so that the velocity of flow of the water in the filter bed decreases constantly and so as to preclarify the water which passes through the bed and subsequently refiltering the preclarified water in a trough basin which rises from the bottom to the top. Thereafter, the refiltered water is directed into a discharge channel from the trough basin which overflows above the basin.
