Signal quality of traditional flame detector

In order to better monitor the normal operation of these boilers, detection safety instruments such as flame detectors and high-energy igniters are essential in the operation of the boiler system. We found that some users are still using traditional flames for various reasons. Detector, flame detector manufacturers to share with you the problems of traditional flame detectors.

The photoelectric detection unit and the signal amplifier are separated by a cable connection. Too many cables cause signal attenuation and poor signal transmission quality.

Traditional flame detectors use analog technology to transmit and are prone to errors

Traditional flame detectors use analog technology to transmit and are prone to errors

The flame detection system uses analog technology to output the signal to the FSSS as a switch signal, which cannot continuously reflect the flame light intensity and frequency characteristics in the boiler furnace. It is prone to misjudgment and mis-sending signals, which will affect the control quality of the system.

Traditional flame detector has poor anti-interference ability

Discrete circuits such as signal detection and signal processing and amplification have poor anti-interference ability, which affects the improvement of system data transmission anti-interference ability and complex maintenance. The human-machine interface adopts simulation technology with low precision

The man-machine interface adopts simulation technology, the setting parameter is single, and the parameter setting accuracy cannot be improved.

Now, the country’s requirements for the safety of boiler combustion conditions are increasing. The country has proposed “maintain the consistency of boiler startup and operation, improve the usability of power plant boilers, reduce maintenance costs, and prevent boiler explosion accidents” for the continuous safety monitoring of boilers. As a general requirement, flame detector manufacturers remind customers to pay attention to the technical details of the product when purchasing related products.
