Description

Technical Field

[0001] The utility model relates to the technical field of boiler flame detection devices, and in particular to a flame detection device. Background Art

[0002] A flame detector is a device used to monitor and identify the presence of flames. In waste gas incinerators, flame detectors are usually used to detect whether there is a flame during the combustion process and trigger corresponding safety measures or alarm systems when necessary. The working principle of the flame detector is usually based on optics, infrared or ultraviolet principles. When a flame exists, the flame detector can sense the specific wavelength or frequency of the flame radiation and convert it into an electrical signal. After processing, these signals can trigger corresponding actions, such as closing the gas valve, activating the emergency alarm system, or taking other safety measures. In waste gas incinerators, the role of the flame detector is to ensure the safety of the combustion process and prevent the flame from getting out of control or accidents. By timely detecting the flame and taking necessary measures, the safety of equipment and personnel can be effectively protected.
