Flame detector
Thread Content
I am assisting in preparing the tender documents for the fire protection project of a new factory. When it came to the topic of flame detectors, I have a question and would like some guidance. The new factory is a baijiu production facility, and the storage area is filled mainly with baijiu with an alcohol content of 30 degrees. I would like to know whether infrared flame detectors, ultraviolet detectors, or combined ultraviolet-infrared detectors should be used for detecting flames there. As long as the relevant specifications are met, that’s fine. I hope everyone can offer some suggestions and advice
If it’s alcohol, choose ultraviolet.
Ultraviolet should be chosen! It’s best to consult the manufacturer.
Okay, I’ll check with the manufacturer specifically, as the design suggestion was to use a composite material, but the boss wants to use a single material instead
What are the characteristics of infrared and ultraviolet light? How to choose a model? Which one is cheaper in terms of cost? Thank you!
I only know that the infrared/ultraviolet combined version is a bit more expensive; I haven’t paid attention to which one, infrared or ultraviolet, is cheaper – it seems they are roughly the same price. Generally, for combustion media with a low molecular weight, ultraviolet light is used, while for those with a high molecular weight, infrared light is employed. For example, simple fuel gases can typically be treated using ultraviolet light, whereas fuel oils usually require a composite approach.
There are three types of flame detectors: one is an ultraviolet detector that is sensitive to the shorter-wavelength ultraviolet radiation in flames； Another type is an infrared detector that is sensitive to longer-wavelength infrared radiation in flames ； The third type is an ultraviolet/infrared hybrid detector that simultaneously detects shorter-wavelength ultraviolet light and longer-wavelength infrared light in the flame. I think I’ll go with the ultraviolet version this time; after all, there’s a difference of over 600,000...
For flame detection of our natural gas, should we use infrared or ultraviolet? Is it composite still? It says online that there are more bands available. How many bands are generally chosen? 2 bands? 3 bands?
