High-pressure cylinder failure under fire condition - investigation of the consequences

Popis výsledku v původním jazyce

This study investigates the behavior of high-pressure hydrogen and nitrogen cylinders under fire conditions toassess the risks associated with their storage and use in industrial and domestic applications. Cylinderspressurized to 300 bar were exposed to flames generated by diesel fuel, with critical parameters such asdestruction pressure, temperature distribution, and fragmentation patterns recorded. The experiments revealeddistinct differences in the destruction mechanisms of flammable and non-flammable gases. Hydrogen cylindersfailed at pressures significantly lower than their rated destruction pressure due to thermal stress, generatingfewer but substantial fragments and a fireball. In contrast, nitrogen cylinders exhibited extensive fragmentationand dispersion with following ignition of diesel vapors, forming a large fireball despite being non-flammable.These findings provide valuable insights into the risks posed by high-pressure gas cylinders under fire exposureand highlight the need for enhanced safety protocols and emergency response measures to mitigate potentialhazards.
