BFS-STRONG Hot Air Furnace Infrared Temperature Measurement System Introduction: A hot blast furnace is a heating and blowing equipment for blast furnaces, and is an indispensable and important component of modern blast furnaces. Modern blast furnaces often use regenerative hot blast furnaces, which work by burning gas first, heating the grid bricks in the regenerative chamber with the generated flue gas, and then heating the cold air from the blast station through the hot grid bricks. Rotate the hot blast furnace alternately for combustion and air supply to continuously obtain high-temperature hot air from the blast furnace. The temperature of the arch of the hot air stove is an important data for safe and accurate operation of the hot air stove. The temperature detection of traditional hot air furnaces is measured through thermocouples, using armored double platinum rhodium thermocouples or other thermocouples to indirectly control the hot air temperature by measuring the temperature of the insulation wall. The refractory lining of the hot blast furnace operates under extremely harsh conditions in high-temperature and high-pressure environments. The requirements of thermocouples for the operating environment and the limitations of their own structure have resulted in inaccurate temperature measurement, delayed reaction, and inability to accurately reflect temperature changes in the furnace in situations of frequent temperature changes, high pressure fluctuations, and vibrations. Thermocouples have been operating in high-temperature areas ranging from 1200 ℃ to 1400 ℃ for a long time, and the environmental temperature of the thermocouple junction box is also as high as 100-120 ℃, resulting in a short service life of the thermocouple, ranging from a few weeks to several months. Increased usage costs and maintenance workload. In order to overcome the above shortcomings, a dedicated infrared temperature measurement system for hot blast furnaces has been designed, which can effectively solve the above problems and ensure the reliable operation of the infrared temperature measurement system in complex environments. characteristic 1. Temperature measurement range: 600 ℃~1800 ℃ 2. Temperature measurement accuracy of 0.5%, repetition accuracy of 2 ℃, resolution of 0.1 ℃ 3. Response time adjustable from 5ms to 99.99s 4.
