Instructions for Temperature Measurement in Coke Ovens and High Temperatures in Coke Oven Chambers I. Instructions for Measuring High Temperatures in Coke Oven Chambers The temperature of the coke oven chambers is a control parameter that directly reflects the level of heating in the coke oven, and it is crucial for feedback regulation. The accuracy and timeliness of measurements directly affect the control effectiveness of the coke oven temperature. Temperature measurement is done manually, with readings taken once every 4 hours. The measurement cycle is long, the time span over which measurements are taken is large, the detection times vary, there are individual differences, and the workload is high. As a result, errors in the measurements are significant, the control cycle is long, and temperature fluctuations are substantial. High-temperature resistant sensing elements are used for long-term online measurement of temperature changes; the acquisition unit converts the temperature values into digital forms for transmission, ensuring timely and accurate data collection, while reducing labor intensity and maintenance needs. The infrared radiation temperature measurement location is the same as the traditional one, facilitating comparison. II. YT-FOS series fiber-optic radiation high-temperature sensors: The YT-FOS series of temperature sensors consist of an optical lens, a high-temperature fiber optic transmission bundle, an integrated filter, a sensor, and an electrical signal processing unit. They are capable of detecting the radiation emitted by the object being measured, determining the temperature of that object based on the intensity of its radiation, and providing a signal output. The optical probe features a stainless steel casing, an extremely large distance coefficient, and an optical fiber bundle that can withstand temperatures up to 300°C, providing excellent protection in industrial environments. It can be easily installed in a variety of complex operating conditions, and is particularly suitable for industrial environments that require heat resistance, long transmission distances, and resistance to strong interference. ?
