WebAug 11, 2024 · The minimum concentration of a particular gas necessary to support its combustion in air is defined as the Lower Explosive Limit (LEL). Below this level, the mixture is too “lean” to burn. The maximum concentration of a gas or vapour that will cause an explosion is defined as the Upper Explosive Limit (UEL). Above this level, the mixture ...

WebFeb 21, 2024 · In practice the LFL of natural gas depends on its precise components and can vary by perhaps 0.5 % GIA in any one year. The LFL is the lowest gas concentration … Webbility (or explosibility) limits (LFL and UFL, respectively) are the limiting fuel concentrations in air that can support flame propa gation and lead to an explosion. Fuel concentrations … 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 … See more 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 … See more Gas and vapor Controlling gas and vapor concentrations outside the flammable limits is a major consideration in occupational safety and health. … See more In the U.S. the most common method of measuring LFLs and UFLs is ASTM E681. This standard test is required for HAZMAT Class 2 Gases and for determining refrigerant flammability classifications. This standard uses visual observations of flame propagation in 5 or … See more Combustion can vary in degree of violence. A deflagration is a propagation of a combustion zone at a velocity less than the speed of sound in the unreacted medium. A detonation is a propagation of a combustion zone at a velocity greater than the speed of sound … See more The flammable/explosive limits of some gases and vapors are given below. Concentrations are given in percent by volume of air. • Class IA liquids with a flash point less than 73 °F (23 °C) and boiling point less than 100 °F (38 °C) have a See more • Chemistry portal • Flammability • Limiting oxygen concentration See more • David R.
