Abstract: The hot partial oxidation gases which are formed in a gasifier for solid or liquid fuel are passed first into a dust separator under conditions where 70 to 95% of the impurities are eliminated, whereupon the gases then are washed in a wet washer with an amount of water not higher than necessary to remove the residual dust impurities. The process has the particular advantage of a very low amount of drainage water and has a high safety factor and adaptability for different conditions.

Abstract: The interior space of a combustion chamber, boiler, or other such gas-filled chamber exhibits an acoustic response spectrum to acoustic energy excitation which includes plural maxima attributable to acoustic natural-vibration frequencies. The frequencies of these natural vibrations are dependent upon both the interior temperature of the chamber and also upon the normality or molarity of the gaseous contents of the chamber. One of these two variables, i.e., temperatures or else normality or molarity, is measured by conventional devices. The other variable is then measured using a pressure transducer generating an electrical signal indicative of the chamber interior's acoustic response spectrum, the transducer output signal being applied to a discriminator circuit which develops a measurement signal indicative of the value of the variable being measured. In this way, interior temperature can be continuously monitored by acoustic devices with high accuracy.

Abstract: An improved coke oven battery and an improved method for production of coke and byproducts are provided. The filling gas escaping during the filling of the oven chambers with coal is initially rendered inert by admixing flue gas. Then the resulting gas mixture of filling gas and flue gas is withdrawn via a conduit fed with flushing liquor from the coke oven gas off-take main and is added to the raw coke oven gas after the coke oven gas off-take main. The tar and coal containing flushing liquor coming from the filling gas conduit is fed back to the coke oven gas off-take main after removal of the tar.

Abstract: A pneumatic or electrical signal indicating the flow mass of a fine-grained fuel suspended in a carrier gas is produced by computer means. The input for the computer is constituted by the quantity determined for the volume of the carrier gas and the quantity determined for the density of the carrier gas together with the quantity determined as the specific weight of the fuel and the quantity determined by a radiometric measurement of the total density of the fuel and carrier gas flow. The computer is programmed to produce the above signal on the basis of a mathematical relationship defined in the above text. A valve controlling the feed of fuel into a gasifier is operated by the signal produced by the computer.

Abstract: A two-stage process, and the apparatus for practicing the process, for cooling process gas are disclosed. The process gas is firstly air-cooled by convection to a temperature above the dew point of naphthalene and finally cooled to the desired discharge temperature by heat exchange with a cooling liquid. The condensed portion of the process gas resulting from the first cooling stage may be utilized to flush the gas conduits of the liquid heat exchanger of the second stage, followed by a recirculation of that condensed portion of the coke oven gas either back through the second stage or by introduction into the stream of process gas prior to its introduction into the first cooling stage.

Abstract: Fine grained fuel such as coal dust is gasified at an elevated pressure by passing the fuel from a supply tank which is at atmospheric pressure by pump means into a pressurized lock basin and therefrom into the gasifier, the fuel during such movement retaining its loose consistency. This can be accomplished for instance by a solid piston pump which is only partially filled with the fuel. Thus, agglomerations are avoided and the fuel is directly conveyed into the gasifier in flowable and fluidizable form without the necessity of being reconverted into a finely divided form.

Abstract: In a coking operation where the heating medium is introduced into the furnace by way of a bottom fire box and wherein heat exchangers are provided for the waste gases, the waste gas is passed through a plurality of parallel channels serving as said heat exchangers and the useful portion of the total system available for such exchange is reduced when the coking time is increased beyond the time required at normal operation.

Abstract: A device for crushing sinter and other material of like consistency is disclosed wherein the flow sinter material is deployed against an impact table which directs the sinter material downward onto a series of vertically disposed discs fixed to a common means of rotation. The common means of rotation intersects each disc through its central axis. Adjacent to the discs and parallel to the common means of rotation is positioned a shaft upon which are mounted crusher means arranged to intersect and pass between the discs. As sinter is directed downward onto the discs, the crusher means rotates and forces the sinter between the discs, thus crushing it. Heat buildup in the discs is controlled by a means of cooling which impinges on the discs.

Abstract: A larry car, a quenching car, a pusher and other such accessory machines travel along the length of a coke-oven battery. Each coke oven is provided with coded structure absolutely indicative of the oven-number of the oven within the battery. The travelling accessory machines are provided with code readers which sense the coded structures and transmit oven-number feedback signals to a central control station. The travelling machines also transmit operation-completed signals upon completion of the individual operations of charging, pushing and the like. A programmed control system at the control station transmits travel-command and operation-command signals in preprogrammed sequences, but the transmission of these command signals is dependent upon the reception of predetermined feedback signals, which establish interlocks serving as conditions precedent to the travel of accessory machines and to their performance of individual operations.

Abstract: After replacement of the walls of one chamber of a coking battery this one chamber is heated up by withdrawing relatively hot air from another still-hot chamber of the coking battery and injecting it into the cold chamber. This is done by means of a conduit extending between the two chambers and provided with an internal nozzle that conducts the hot gas from the hot chamber to the cool chamber by jet-pump action. This hot gas is mixed with relatively cool air so as slowly to heat the cool chamber up.

Abstract: A flexible seal member is secured to the periphery of the body of a coke oven door that is shaped to the contour of the receiving door jamb of the coke oven body. A seal edge of the seal member contacts the jamb in sealing relation. A plurality of spring pressing elements secured to the periphery of the door exert a constant sealing pressure on the seal member to maintain the seal member in sealing relation with the jamb. A plurality of stop mechanisms arranged on the periphery of the door maintain a preselected distance between the fastening point of the seal member to the door and the sealing surface of the jamb. A plurality of latching mechanisms positioned at selected regions on the door and secured to the coke oven body are operable to bend the door according to the contour of the jamb as the door experiences deformation during the coking operation. The bending of the door is also enhanced by reducing the moment of resistance of the door by providing longitudinal recesses therein.
