Operating principle of burner flame detectors

In the control system of a burner, the flame detector is an important component, responsible for the calibration of the gas flame, the yellow or blue fuel flame and the ignition spark. Based on decades of project experience of EBICO engineers, we offer a unique insight into the operating principle of burner flame detectors.

Due to the different detection bands, they can be divided into UV, visible light, infrared and full radiation flame detection. Flame detection signals come from UV detectors and smoke detectors. Among the above burner flame detectors, the use of radiation light energy principle of the burner flame detector is the most widely used, but also more effective burner flame detector method. The principle of radiation light energy intensity detection is to use the probe to receive the radiation emitted by the flame, according to its intensity to determine the presence or absence of flame.

The radiation of a flame is gaseous radiation with a discrete spectrum and solid radiation accompanied by a continuous spectrum with wavelengths in the range of 0.1-10 μm or wider. The UV flame detection technology, which successfully makes the system avoid the most powerful natural light source a complex background caused by the sun, makes the burden of information processing in the system is greatly reduced. In addition, it is a photonic detection means, and thus a high signal-to-noise ratio, with very weak signal detection capabilities, in addition to its extremely fast response time. Compared with infrared detectors, UV detectors are more reliable and have high sensitivity, high output, high response speed and simple application lines. Therefore, UV burner flame detector is increasingly widely used in combustion monitoring, fire self-alarm, discharge detection, UV detection, and UV photoelectric control and other fields.

That's how the burner flame detector works. EBICO Online Parts Mall provides customers with flame detectors of famous brands such as Siemens and Dulag, and provides accessories maintenance consulting services at any time; Welcome to https://cn.ebico.com/parts/ to learn more about.
