How to choose a flame detector
Thread Content
The fuels for the boilers are blast furnace gas, coke oven gas, and natural gas respectively. How should one choose a flame detector at the time of installation, and how can it be determined that the fuel has ignited after it is added? This post was last edited by yps_78 on 2009-3-17 09:43]
To detect the flame of the fuel gas, an ultraviolet flame detector should be used for single-nozzle detection; the valve is shut off if no flame is detected within approximately 3 seconds. Check the specific terms of FSSS in detail. Additionally, flame detection equipment should be equipped with flame detection cooling air auxiliary devices. There is now a type of image-based flame detection device; unlike conventional flame detectors that can only detect the presence or absence of a flame, image-based flame detection uses algorithms for detecting the temperature of the flame. For more details, one can refer to the book \"Principles and Techniques of Visual Flame Detection in Furnaces\".
May I ask if there are specific manufacturers for the “device for image-based flame detection” you mentioned?
The company registered by Professor Zhou Huaichun from Huazhong University of Science and Technology in Wuhan has a patented product. Professor Zhou has dedicated decades to his research. The product performance has improved a lot. I’ll find some information to send you and let you take a look.
