Invisible Danger: Detecting hydrogen flames
Slide 2: Firestarter hydrogen
Firestarter hydrogen Hydrogen can be a safety challenge: Nearly one third of reported incidents resulted in fire, half in explosions. Consequences of reported hydrogen related events 48% Explosion 6% Near miss 15% 31% Unignited release Fire
Slide 3: Safety challenges of hydrogen
Safety challenges of hydrogen Leaks easily and can Has a 15 times lower Is ignitable even in diffuse containment level of ignition low concentrations materials due to its energy than methane in air (≥ 4 %) small molecules Is 14 times lighter Is nearly than air and dilutes invisible to the quickly in
Slide 4: Why are hydrogen flames special?
Why are hydrogen flames special? The properties of flames can vary drastically depending on the chemical composition of the burning material and its immediate reaction products, especially for hydrogen flames. Comparison hydrocarbon fire vs. hydrogen fire Hydrocarbon Hydrogen Visibility Visible in d
Slide 5: Hydrogen flame detection
Hydrogen flame detection Due to their properties, hydrogen flames are barely perceptible to human senses and some flame detectors. Which flame detectors are suitable for hydrogen fires? UV/IR detector IR3 H2 detector Fast Fast reaction time reaction time Medium detection Large detection Pros distanc
Slide 6: When reliability is a factor
When reliability is a factor Hydrogen flames emit electromagnetic radiation at a specific wavelength, making IR3 H2 detectors particularly suitable and reliable when worker safety is at stake. Wavelengths measured Wavelengths measured by UV/IR detector by IR3 H2 detector 8 8 6 6 Emission Emission 4
Slide 7: Increase safety with a matrix of technologies
Increase safety with a matrix of technologies Hydrogen flame detection is best combined with other technologies like catalytic point gas and UGLD to maximise safety. Flame detection with the Point Gas Detection with Ultrasonic Gas Leak newest generation of catalytic bead transmitter Detection with T
