WebThe auto-ignition temperatures of hydrogen and natural gas are very similar. Both have auto-ignition temperatures, much higher than that of gasoline vapor, as shown in Figure … WebSep 1, 2024 · The LFLs were within the range of 0.032–0.040 in terms of the fuel-air mass ratio for all four aviation fuels in the temperature range of 350–420 K. Unlike temperature, pressure had a minor influence on the lean flammability limit. For all measured samples (pure hydrocarbons and fuels), the lean limit decreases with increasing molecular weight.

It provides information on industry experience with flammable vapor clouds, basic concepts of fires and explosions, and an overview of related computer …
WebMoreover, the flammability range is wider meaning the concentrations in the air required to have a fire are wider for hydrogen (4-76%) than for kerosene (1.4-7.6%) [3]. On the other hand, the lower flammability limit is higher for hydrogen than kerosene (4% vs 1.4%). This means that if the
