[0002] Glass fiber is widely used in electrical appliances, transportation, construction, aerospace, aviation, environmental protection and other fields due to its unique properties such as mechanical strength, insulation, corrosion resistance, thermal insulation and sound absorption.
[0003] Among them, the glass fiber needs to be fired at a high temperature of 1500-1600℃ in a pool kiln. During the firing process, the oxygen content inside the pool kiln needs to be strictly controlled to prevent the glass fiber from being oxidized and affecting the pass rate of the glass fiber.
[0004] At present, the detection of oxygen content inside the pool kiln still has certain limitations in actual detection due to the special high-temperature environment. For example, when flame jets occur, the oxygen content cannot be accurately detected in real time. Utility Model Content
