摘要： An arrangement for regulating the introduction of substances into chambers is disclosed and is particularly well-suited for the feeding of coal into coke ovens. The arrangement includes a chamber which is to be filled to a predetermined level and a feeding device is provided for feeding material into the chamber. The feeding device has a switch which stops the introduction of the material to the chamber when the level of the material reaches the predetermined level. The switch for the feeding device is electrically connected with a differential pressure switch which is actuated upon the generating of a predetermined pressure differential across it. The requisite pressure differential is generated by introducing pressurized gas into the chamber and an air compressor may be provided for this purpose. A sensing conduit, which is connected with one terminal of the differential pressure switch, extends into the chamber and has an end positioned at the predetermined level to which the chamber is to be filled. The pressurized gas admitted into the chamber sets up certain pressure characteristics in the sensing conduit which are changed when the level of material in the chamber reaches the predetermined level so that the gas no longer has free access to the open end of the sensing conduit. The change in the pressure characteristics causes a pressure differential to be established across the differential pressure switch which, in turn, activates the feeding device switch to stop the introduction of material into the chamber. In order to compensate for shock waves which may be generated in the chamber by the feeding of the material and which may cause a false signal to be transmitted to the switch of the feeding device, a compensating conduit is provided which has an end in the chamber and is connected with the terminal of the differential pressure switch opposite that to which the sensing conduit is connected. A supply conduit for the pressurized gas is also provided and introduces the pressurized gas into the chamber in the vicinity of the end of the sensing conduit.

摘要： A method and an apparatus are disclosed for drying and preheating coking coal particles of mixed sizes in a flight stream tube. A stream of hot gas in which different-size particle fractions are entrained, is advanced through the tube. At one or more locations it is split up into two flows, one containing the smaller fractions and the other containing the coarser fractions. The coarser fractions are slowed and readmitted into the flow having the smaller fractions, counter to the direction of advancement of this flow.

摘要： The gas-tight closure comprises a thin walled tubular piece projecting from a feeding duct into a filling space, a thin walled conical jacket having its larger bottom base provided with a rigid seal reinforcing member cooperating with the lower rim of the intake tubular piece. The outer periphery of the reinforcing member is slanted about a small angle to snugly fit into the tubular piece and adjust the form thereof when upward pull is exerted upon the conical jacket by means of an actuation rod passing outwardly through the wall of the feeding duct. The actuation rod has preferably the form of a hollow shaft which accommodates the manipulation rod of a scraper projecting radially below the reinforcing member into the filling space. The outside portion of the actuation rod is provided with a control device in the form of clamping plates cooperating with abutment plates resting on the guiding sleeve for the actuation rod. The clamping plates are manipulated by means of separate levers.

摘要： Method for charging a coke oven chamber. Where the chamber is charged through a single charging hole with a stream of flowable preheated particulate coal at a flow rate of between substantially 8-20 tons per minute. The coal flows sufficiently in the chamber to assure filling of the chamber to substantially 100% of the volumetric capacity of the same. Due to the flowability of the preheated coal the charge is self-leveling.

摘要： A plurality of coking ovens are arranged in a horizontal row, and an endless scraper conveyor is mounted above the charging holes of the ovens and has an upper run and a lower run. A quantity of coal is admitted onto the lower run of the conveyor at one end portion thereof to be transported lengthwise of the row. Coal is charged from the lower run into respective ones of the ovens in a sequence which progresses from a downstream end of the row counter to the direction of transportation, and the charging of each oven is terminated when a signal is generated that indicates that a predetermined filling level in the oven has been reached.

摘要： Coal is preheated and contacted with 0.5 to 3 percent by weight of moist coal tar, preferably bituminous coal tar. The thus-treated coal is admitted into a coke oven through the ceiling of the latter. The coal is poured into the coke oven, rather than being blown in, and is permitted to descend into the coke oven under the influence of gravity. Preferably, the coal is poured into the coke oven through at least two or three openings in the ceiling thereof. The coal tar serves to bind finely divided coal particles to the coarser particles and, in this manner, the development of dust during the introduction of the coal into the coke oven is restricted and, concomitantly, the danger of ignition or explosion is reduced.
