ABB火檢光纖SF810介紹
ABB火焰探測(cè)光纖SF810系列，具有多年的研發(fā)經(jīng)驗(yàn)。
紅外火焰探測(cè)器的原理：火焰中有大量可見(jiàn)光和0.9m以上的紅外線。這些波長(zhǎng)的光不易被煤塵，水蒸氣和其他燃燒產(chǎn)物吸收，因此適用于檢測(cè)煤粉火焰，重油火焰以及惰性氣體含量高的燃料的適當(dāng)燃燒。紅外火焰檢測(cè)通過(guò)檢測(cè)燃燒火焰發(fā)出的紅外線強(qiáng)度和火焰頻率來(lái)確定火焰的存在。該探頭使用硫化鉛光電管或硅光電二極管。由于爐膛的火苗在火焰區(qū)被*燃燒，因此火苗的頻率通常不超過(guò)2HZ。因此，紅外火焰探測(cè)器可以通過(guò)過(guò)濾器電路區(qū)分燃燒器火焰和背景火焰。
ABB flame detection fiber SF810 series, with many years of research and development experience.
Principle of Infrared Flame Detector: There is a large amount of visible light in the flame and infrared rays above 0.9m. These wavelengths of light are not easily absorbed by coal dust, water vapor, and other combustion products, so it is suitable for detecting pulverized coal flame, heavy oil flame, and suitable combustion of a fuel with a large inert gas content. Infrared flame detection determines the presence of flame by detecting the intensity of the infrared rays emitted by the combustion flame and the flame frequency. The probe uses a lead sulfide photocell or a silicon photodiode. Since the furnace flicker is completely burned in the flame zone, the flame flicker frequency usually does not exceed 2HZ. Therefore, the infrared flame detector can distinguish between the burner flame and the background flame through the filter circuit.
