Fireye 3G-OTH-02861 — Technical Specifications

The UV scanner is ideally suited for gaseous fuels (natural gas & propane). However, it can be used in detecting flames from standard fuel gases, some waste gases and light oil fuels such as No. 2 oil. Flames from heavier oils can be detected with UV scanners but the unburned fuel shroud and/or atomization shroud can block the passage of the UV from the flame zone to the UV tube, causing nuisance burner/boiler trips. Infrared detection is recommended for fuel oil heavier than No. 2, and some installations where waste gases are burned together with natural gas as the main flame.
