Gas that ignites when in contact with oxygen
WebSep 20, 2024 · The lower explosive limit (LEL) is the minimum concentration of a specific combustible gas required to fire combustion when in contact with oxygen (air). If the concentration of the gas is below the LEL value, the mix between the gas itself and the air is too weak to spark. The upper explosive limit (UEL) is the maximum level of concentration ... WebThe Flammable Range (also called Explosive Range) is the concentration range of a gas or vapor that will burn (or explode) if an ignition source is introduced.. Three basic requirements must be met for explosion to take place: flammable substance - fuel; oxidizer - oxygen or air; source of ignition - spark or high heat
