FSE-100 Integral Explosive-proof Intelligent Flame Detector

FSE-100 Explosion-proof Flame Detector is used to collect the flame signal which is amplified and processed to determine the presence or absence of flame，integrating with ultra-violet (UV) and infra-red (IR) sensors. FSE-100 Flame Detector provides the flame output in real-time – the basis of determining the presence or absence of flame. The detector is suitable for both oil and coal fired applications.

Product Details

Principle

FSE-100 Explosion-proof Flame Detector divides the flame signal into strength signal and frequency signal in the first place, which indicates the flame luminance and the flame flicker respectively.

The frequency signal contains spectrum, bandwidth and peak-peak value, etc. The flame frequency is 1~200Hz, while the frequency of the coke button and ash in the boil furnace is less than 2 Hz. Therefore, the presence or absence of the flame can be determined by analyzing the frequency signal.

FSE-100 detects the flame quality to determine the presence or absence of flame by amplifying, filtering and computing strength and frequency signal as well as processing the signal of flame characteristics.

Installation

Flame Detector Angle

The observation angle and the burner centerline should be set at a small angle

(recommended 5- 10 degree), ensuring maximum monitoring of a flame's initial combustion zone, and obtaining the best observation effect.

Straight conduit installation method

It is a direct-view way to observe the target flame which is viewed through a straight conduit. This method is best suited for water-wall boilers and W-shape burners.

Optical fiber installation method

The target flame can be detected via the optical fiber transmission system with an adjustable observing angle. It's easy to install without installation space limitation. The observing method is applicable for all types of burners in coal-fired power plants.
