Abstract: A pyroscrubber for combustion of large carbon particles in a stream of waste gas, particularly the waste gas from a coke calcination furnace comprises a generally U-shaped combustion chamber having a first passage arranged parallel with (preferably above) a second passage, so that there is a reversal in gas flow direction between the two passages. The combustion chamber has an exhaust gas inlet and an array of air inlets at the inlet end of the first passage. A gas outlet preferably leads laterally out of the side of the structure at the outlet end of the second passage to secure an abrupt change in the direction of gas flow.

Abstract: A coke guide machine includes a shuttle car carried by rails on a coke bench for a battery of coke ovens. Movable along the shuttle car is a carriage having two support stations that are rotatable about a common vertical axis. The support stations include scissor arms that form extendible support devices, one of which carries a handling device for a coke oven door and the other carries a device adapted to clean exposed sealing surfaces of an emptied coking chamber. 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 cleaning tool for door jamb surfaces of a coke oven chamber includes: a sleeve fixed to a frame that is movable toward the door jamb; a plunger resiliently mounted in the sleeve; a support fixed to the plunger; and a multi-sided scraper tool rotatably mounted to the support. Two such cleaning tools may be used to clean the inside and the outside door jamb surfaces.

Abstract: The arrangement comprises a working member formed by a pair of intercommunicating nozzles of which one nozzle comprises a bellmouth mounted above the oven platform with a certain spacing, facing with its enlarged portion the bottom part of the oven and intimately adjoining this part upon engaging the oven, and the second nozzle is of cylindrical shape and has an ejector communicated with a compressed gas source for reducing pressure within the nozzles, whereby the first nozzle functions as a suction nozzle to collect the remainders of coke from the platform, and the second nozzle functions as a delivery nozzle to project the collected remainders of coke into the oven chamber.

Abstract: A cleaner head is pivotally mounted to a shaft carried by an actuating arm that is so powered that, as the actuating arm pivots about an axis, the cleaner head, which is resiliently biased, engages and cleans the bottom surface of a coke oven door plug or lining.

Abstract: A coke oven decarborizing air regulating assembly comprising a manifold pipe extending along each side of a battery of coke ovens for feeding gas to a plurality of separate pipes leading to burners in the ovens, each of which pipes includes an air regulating assembly comprising a cylindrical pipe section with a plurality of holes cooperating with the edge of a relatively slidable cylindrical sleeve having an end plate or "cookie" with a handle for slidably moving the sleeve longitudinally to quickly regulate the amount of air introduced into the oven. The handle also serves as a stop element to prevent abnormal insertion of the sleeve into the pipe -- also it may predetermine the normal opening of the air admitting holes.

Abstract: An improved by-product coke oven wherein the ends are heated through the doors or jambs to prevent condensation of the tar and the deposit of carbon and coal. This improved coke oven possesses improved sealing features and minimizes pollution during coking and during the extraction of the doors.

Abstract: A water distillation unit is disclosed herein. The unit preferably comprises an upper boiler container and a lower condensation container which are rigidly maintained in spaced apart relationship by a molded coupling member containing a plurality of water passageways and fittings. The coupling member is integral with the condensation container and is removably and threadably attached to the upper boiler container so that same may be easily removed when desired for cleaning. The boiler container receives raw liquid which is vaporized by an interiorly disposed heater element. The condensation container houses a condenser tube which receives steam from the boiler container and conducts distillate exteriorly of the apparatus. To improve thermal efficiency the condenser tube is cooled by raw liquid which is routed through the condensing container.

Abstract: Process and apparatus for removing carbon deposits from the inner surfaces of a coke oven gas offtake by introducing steam into the gas offtake in an amount and under conditions sufficient to remove at least a portion of said carbon. The steam may be introduced either countercurrent to, or in the direction of, the flow of the gases exiting through the gas offtake.

Abstract: In one embodiment valve means are provided in the pipe connecting the fuel gas main and air supply main to the respective headers to simultaneously supply a portion of the air to the headers associated with the "on" flues and a portion of the air to the headers associated with the "off" flues. The air supplied to the headers associated with the "on" flues mixes with and dilutes the rich fuel gas to suppress the tendency to deposit carbon in the vertical riser ducts of the "on" flues. The air supplied to the headers associated with the "off" flues removes the carbonaceous material deposited in the vertical riser ducts of the "off" flues. In another embodiment induction or recirculation ducts are provided between the vertical riser ducts of interconnected flues to admix a portion of the waste gas from the "off" flues with the rich fuel gas flowing upwardly through the vertical riser ducts of the "on" flues.

Abstract: The coke oven cleaner is capable of scraping particularly the entrance areas of a coke oven automatically to remove tar and the like adhered thereon completely, and comprises an upright stationary holding or support frame mounted on a door lifter, and a first scrapers-holding frame movable up and down the stationary holding frame and carrying first scrapers arranged to engage the door sealing surface of the coke oven entrance. A second scrapers-holding frame is movable with the first scrapers-holding frame and carries second scrapers engageable with the interior surfaces of the door frame and with the brick lining of the coke oven. Heat-blocking plates are movable with the first and second scrapers-holding frames. The second scrapers-holding frame comprises a pair of interdependent substantially parallel upright members interconnected by linkages, similar to toggle linkages, for movement laterally toward and away from each other by a hydraulic actuator or the like acting on one of the linkages.
