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 (LEL). At a concentration in air lower than the LFL, gas mixtures are "too lean" to burn. Methane gas has an LFL of 4.4%. If the atmosphere has less than 4.4% methane, an explosion cannot occ…

It has a vapor pressure of 32.5 kPa (244 mm Hg) at 20 °C and is stable to soda lime. …
WebThe terms flammability limit (FL) and explosion limit (EL) have often the same meaning. In Europe the term “explosion limit” is frequently used as in the ATEX directives and in EN 13237:2012 [6]. In the US literature and in international standardization the wording “flammability limit” or “flammable limit” is more common.
Web摘要： There is a clear difference between exiting data on the measured flammability limits of hydrogen-air mixture. The non-uniformity of concentration distribution of hydrogen in air is a contributor to deviations of the upper flammability limit (UFL) and the lower flammability limit (LFL) measured in different experiments. WebThe lower explosive limit, or LEL, is the lowest atmospheric concentration of fuel in the fuel-air mixture at which a gas or vapor can explode (the similar and often interchangeable …
WebApr 28, 2012 · pressure and temperature on flammability limits is poorly understood. LeChatelier’s rule can be used to provide an initial estimate of the flammability limits for mixtures of gases, although experimental verification is always advised: where LFL mix is the lower flammability limit of the mixture, n is the number of combustible species, y i
WebSep 19, 2024 · One hundred percent lower explosive limit (100% LEL) denotes an atmosphere in which gas is at its lower flammable limit. The relationship between percent LEL and percent by volume differs from gas to gas. The example below demonstrates the flammability of Methane (Natural Gas) in Air.
