Abstract: This disclosure pertains to an apparatus within a container wherein solid particles of the type that form a sediment in a liquid, are withdrawn from a liquid-filled processing chamber at the upper side of a funnel-shaped plate into a liquid-filled collecting chamber below the plate. In one embodiment, the funnel-shaped plate includes a central discharge nozzle that forms an annular discharge gap by extending downwardly within the side walls of a bell-shaped chamber that is inverted and contains a mushroom-shaped distributor supported above its bottom wall by a liquid supply pipe. The top surface of the mushroom-shaped distributor has a conical shape with the apex extending upwardly to the terminal end of the discharge nozzle.

Abstract: The control system includes a controller and a clocking circuit along with a computer for each one of the coke oven chambers. A first control signal is responsive to the occurrence of charging coal into a given oven chamber and starts the clock. A second control signal is responsive to the pushing of coke from the oven chamber and stops the clock. When the duration of the coking time for a given oven chamber exceeds a predetermined coking time, the controller provides a signal for operating valves to terminate the flow of combustion gases into heating flues at the sides of that coke oven chamber. In the system, the computer updates coking time and establishes from time-to-time from data fed to it, the thermal state of each heating flue in the battery.

The carriage also supports a coke guide including an extendible section to bridge an open passageway wherein an inspection car moves along the coke bench between the shuttle car and the coke ovens. A door cleaning machine is positioned in a stationary manner on the shuttle car to clean a coke oven door carried to it by the door handling device after 180.degree.

Abstract: A process to remove ammonia from gases by washing the gases with an inorganic acid of ammonium bisulfite. The ammonia removed from the gas transforms the washing liquid into ammonium salt solution. This salt solution then undergoes a separate processing by washing it with gases bearing sulfur dioxide to regenerate ammonium bisulfite acid, a portion of which is returned for further washing of the gases and another portion is diverted to an apparatus for concentrating the acid solution up to 70% to 80% by weight after which the concentrated acid solution is delivered to a combustion chamber where burning thereof produces combustion products bearing sulfur dioxide which are used in the process to wash the ammonium bisulfite salt solution to regenerate ammonium bisulfite acid.

Abstract: A charging car supports a plurality of hoppers in a manner such that two hoppers for supplying coal to adjacent charging holes are supported one after the other in a consecutive relationship along a line which is generally parallel to movement by the charging car. A conveyor conducts coal from each hopper to a telescopic charging tube which communicates with the charging hole in the roof of a coking chamber. Skirt-like walls enclose the sides of the spaces containing two of the hoppers to conduct smoke and other gases upwardly toward a roof which is supported by stanchions at each side of the battery of coke ovens. In one embodiment, two roof sections extend from the sides of a battery of coke ovens toward the center thereof. Gas-conducting mains receive gases via outlet pipes having control valves from the spaces beneath the roofs.

Abstract: Regenerative heating of a coke oven battery includes the combustion of lean gas and air in heating chambers disposed between the coking chambers or, alternatively, if desired, the combustion of rich gas and air in the heating chambers. Each heating chamber includes a plurality of header walls forming upgoing and downgoing heating flues. Each header wall includes at least one internal duct in open communication with a plurality of vertically-spaced exit ports at the common side of a header wall. The internal ducts receive either preheated air or preheated lean gas for combustion in a heating flue. The cross-sectional size of the exit ports to discharge air in a given heating flue increases upwardly from port to port along the header wall whereby the amount of air supplied at the sole and lower part of the heating flue is insufficient for complete combustion of the amount of lean gas supplied thereto.

Abstract: Fine-grain fuel is carbonized at a low temperature by feeding the fuel from a hopper downwardly into the gap formed between two vertically-arranged, plate-type conveyors. The plates of each conveyor move downwardly while their back face surfaces bear against the wall of a heating chamber. The position of the heating chambers is controlled to maintain a narrow gap, e.g., 10-30 millimeters between the plates of the conveyors. The conveyors and heating chambers are located within a container wherein a pressure of up to 100 bars is maintained and a clear gas is passed countercurrently to the downward advancement of the fuel in the gap between the conveyors. Breaker rollers below the conveyors subdivide the carbonized fuel issuing from the gap for passage into a gasification chamber. Part of the gas yield is used as fuel for the heating chambers.

Abstract: Liquid slag passes from an overflow in a pressure vessel into an underlying collecting vessel where the liquid slag is transformed into solid granular material by quenching in a liquid coolant. A desired coolant level is maintained within the collecting vessel by control valves under a pressure above atmospheric pressure. Two slide valves in the bottom of the collecting vessel are opened to discharge the granular material after accumulating to a predetermined measured level which is below the liquid coolant in the collecting vessel. A discharge vessel, beneath the collecting vessel, receives the discharged granular material. The discharge vessel is filled with a liquid coolant under either atmospheric pressure or under the same elevated pressure as the pressure within the collecting vessel.

Abstract: Disclosed is an apparatus including a probe adapted for removal through an aperture in the side wall of a high pressure chamber. The probe is supported at one end of a rod that is coaxially received within a sleeve. A plate at the free end of the rod forms a sealed connection between the rod and the sleeve. The sleeve extends within a tube attached at one end to the high pressure chamber in an enclosing relation with the aperture therein. The tube is divided along its length and secured by flanges to a valve used to selectively block the flow of media from the high pressure chamber after the sleeve is withdrawn along the tube beyond the valve. Screw threads on the external surface of the sleeve mate with internal screw threads formed in a screw head that is supported by the end of the tube to displace the sleeve therealong.

Abstract: To quench hot coke it is delivered to the surface of water in a tank, where the coke floats. The coke is carried along the surface of the water until it becomes saturated and sinks, whereupon it is removed from the tank. The water adhering to the removed coke is allowed to evaporate.

Abstract: In a horizontal coke oven, the regenerators therefor include columns of superimposed checkerbricks supported at their lower ends on horizontal partitions forming stationary ports that conduct gaseous media between an underlying sole flue and the various sections of the regenerator. Movable plates with portal openings contiguous with the stationary ports are adjustable in the direction of the length of the sole flues for determining the extent to which the stationary ports are masked by the plate. Grooves are formed at the underside of the stationary ports for guiding the side edges of the movable plates. Pegs extend from the lower surface of the plates. In one embodiment, trough-shaped support members in the sole flue carry an adjusting rod that extends along the flue from the coke discharge side of the oven. Fingers extend radially from the rod to engage the pegs to move the plates in an adjustable manner.

Abstract: Coke oven gases are washed with an aqueous metallic salt solution of sulfuric acid or sulfurous acid to absorb ammonia, hydrogen sulfide and hydrogen cyanide. The washing solution is then oxidized to recover elementary sulfur. A portion of the oxidized washing fluid is returned for continued washing of gas and a portion of the washing fluid is diverted to a separater where solid compounds which include metal hydroxide and metal cyanide compounds are removed leaving ammonium sulfate solution. The ammonium sulfate solution is heated with combustion air and in a heating agent to produce combustion products including nitrogen, hydrogen and an acid anhydride. The solid compounds from separater are conducted as a aqueous suspension to a reaction vessel wherein, at elevated temperature and pressure, hydrolysis products are formed including free ammonia, metal hydroxide and formate salts.

Abstract: At the machine side of a coke oven, a leveling rod is moved into a coke oven chamber through an opening surrounded by a frame on a removable oven door. A movable hood is positioned to define a horizontal extension to the opening in the coke oven door to thereby enclose a portion of the leveling rod during its movement into the oven chamber. A support member within the hood is arranged below the lower edge of the frame that surrounds the opening in the door. Bracket plates are carried by the support member such that the leveling rod moves upon the top surface of the uppermost plate. A removable bolt is employed to secure the bracket plates to the support member. The number of bracket plates used determines the elevation at which the leveling rod moves into the oven chamber. An extension insert is removably attached to the roof of the hood above the leveling rod.
