# Flame Detection #detection-technology #fire-detection #sensor Flame detection systems identify fires by detecting the characteristic radiation emitted by flames, using UV, IR, or combination sensors. ## Detection Methods ### UV (Ultraviolet) Detection - Detects UV radiation from flames - Fast response time - Sensitive to UV sources (sunlight, welding) - May have false alarms ### IR (Infrared) Detection - Detects IR radiation from flames - Less affected by ambient light - Multiple IR wavelengths for selectivity - Can distinguish flame flicker patterns ### Combination UV/IR - Uses both UV and IR sensors - Reduces false alarms - More reliable detection - Better discrimination ### Visual Flame Detection - Advanced detectors using visual spectrum - Can distinguish between flames and other radiation sources - Useful in high ambient light conditions - Can identify actual flames vs. site radiation ## Applications - Industrial fire protection - Oil and gas facilities - Chemical plants - Warehouses - High-risk areas ## Limitations - Environmental interference (ambient light, smoke, steam) - Line-of-sight required - May be blocked by obstacles - Requires proper placement and maintenance ## Best Practices - Site assessment for optimal placement - Consider environmental conditions - Regular maintenance and cleaning - Use advanced detectors in challenging environments - Account for line-of-sight requirements ## Related Concepts - [[IR Absorption]]
