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. Also means are provided for sensing either the temperature of pressure in the operating system lines which is connected to the means for shifting the operation from one mode to another after the measured values vary beyond a predetermined operation pattern.
