Lower flammability limit Lower flammability limit (LFL): The lowest concentration (percentage) of a gas or a vapor in air capable of producing a flash of fire in the presence of an ignition source (arc, flame, heat). The term is considered by many safety professionals to be the same as the lower explosive level … Visa mer Mixtures of dispersed combustible materials (such as gaseous or vaporised fuels, and some dusts) and oxygen in the air will burn only if the fuel concentration lies within well-defined lower and upper bounds determined … Visa mer The flammable/explosive limits of some gases and vapors are given below. Concentrations are given in percent by volume of air. Visa mer In the U.S. the most common method of measuring LFLs and UFLs is ASTM E681.

For example, we get the lower and upper flammability limit of 1% to 10% based on the Flammability diagram for crude oil.
Webbrelative humidity. The flammability limits of hydrogen–air mixtures are between 4.1 and 75% by volume of hydrogen in air at atmospheric pressure and room temperature, and increase almost linearly with increasing temperature. The large value of 75% for the rich flammability limit is linked to the small value of 5% for the limiting oxygen index, Webbflammability limit was obtained with a subsequent incorporates both internal and external heat recircu- maximum gas temperature less than 1800 K leading lations.
