1. Use three-band infrared flame detectors outdoors in petrochemical projects, and use dual-band infrared flame detectors indoors.
2. Use infrared/ultraviolet composite flame detectors in explosives and gunpowder factories.
3. Use ultraviolet flame detectors for metal and inorganic flame detection in indoor environments. Infrared flame detectors can be used for underground hydraulic stations and lubricating oil depots. Ultraviolet flame detectors or single-band infrared flame detectors cannot be used outdoors.
Precautions for installation and use of flame detectors
1. When installing and wiring the flame detector, the monitored area should be within the effective range of the field of view.
2. The installation of flame detectors should avoid obstacles as much as possible. For obstacles with horizontal and vertical dimensions not exceeding 0.5 meters, the distance between the detector and the obstacle should not be less than 2.5 meters; for obstacles with dimensions exceeding 0.5 meters and cannot be avoided, the number of detectors should be appropriately increased.
3. The installation height and position of the flame detector should be determined according to the sensitivity level of the detector. The distance between the detector and the monitoring target can be determined according to the characteristics of the fire, generally not less than 1.5m.
