Flammability range of jet a
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 WebJet A-1. Jet A-1 is a kerosine grade of fuel suitable for most turbine engined aircraft. It has a flash point minimum of 38 degrees C (100°F) and a freeze point maximum of -47 degrees C. It is widely available outside the U.S.A. The main specifications for Jet A-1 grade (see below) are the UK specification DEF STAN 91-91 (Jet A-1) Nato code F ...

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. WebFlammable fuels have a flashpoint below 38°C. and combustible fuels have a flashpoint above 38°C. As an example, diesel fuel flashpoints range from about 50°C. to around 100°C making it relatively safe to transport and handle. Gasoline, by comparison, has a flashpoint of minus 43°C. Sparks and static electricity can easily ignite gasoline fumes.
