  • Patent number: 4574034
    Abstract: A method of monitoring the reversal system of coke oven batteries comprises monitoring the position of the air valves, waste heat discs, and gas cocks in each of the coke ovens of a battery, measuring and centrally registering the temperatures and/or flow rates of the fluids supplied into and discharged from the oven, namely of combustion air, gases and waste gases, comparing the measured values with the desired values corresponding to the position of the system elements, and upon an undue deviation, signals for carrying out safety measures, such as actuating a gas deficiency safety, are automatically delivered. Also measured may be the oil pressure in the lines for supplying the hydraulic signals actuating the reversal mechanism, with again a release of alarm signals. A device for monitoring the reversal system includes an apparatus connected to the valves for shifting all of the valves between an operating position in one characteristic way to an operating condition in another characteristic way.

  • Patent number: 4263100
    Abstract: A method reducing fine dust emission during the time that predried and preheated coal is charged into coke ovens comprises directing wet coal to be carbonized into direct contact with a hot process gas so that the coal is transported dry and heated, directing the hot process gas with the heated coal to a plurality of different separators in succession with the first separator being set to separate only around from 80 to 90% of the total amount of the coal and without separating the fine dust, and a subsequent separator separate the remaining amount of the solid matter including the fine dust, compacting the dust removed from all of the separators and mixing them together, and charging the compacted mixed dust into the coke oven. The apparatus for effecting the invention includes a material separator which is designed as a gravity separator or gravity sifter which is arranged to discharge into a connection between the mixed and compacted dust separator in separate additional separators.

  • Patent number: 4247366
    Abstract: A method of preparing and delivering coal to a coking plant, comprises, conveying the coal to the plant on a moving conveyor while an inert combustion gas is directed over the coal being conveyed. The combustion gas is generated by burning a fuel with air to produce a substantially inert combustion gas which is passed over the coal during its conveying and, thereafter, passed through a cooler for removing the moisture which has been picked up from the coal by the gas. The heating and predrying inert gases are advantageously generated by the direct combustion of air and fuel which are passed through flash dryer tubes and one or more separate separator systems and then delivered into a conveyor pipeline through which the coal is conveyed. A portion of the gases which are generated are also directed with a return gas to a filter for removal of any coal therefrom and to a cooler for removing the moisture picked up from the coal and then back into the stream for delivery to the conveyor for the coal.

  • Patent number: 4064017
    Abstract: A cokable substance such as coal is admitted into a coking chamber. A quantity of heat which is sufficient to cause coking of the cokable substance is supplied to the chamber during preselected time intervals within the coking period in which coking of the cokable substance progresses in response to the supply of heat. On the other hand, during other time intervals within the coking period in which coking of the cokable substance is essentially unaffected by the supply of heat, the quantity of heat supplied to the chamber is reduced to a level below that required to sustain coking of the cokable substance during the preselected time intervals. In this manner, savings in energy may be realized. The supply of heat to the chamber during those time intervals in which coking of the cokable substance is unaffected by the supply of heat may be discontinued completely.
