Flammability range of methane

WebThe lower flammability limit decreases slightly as pressure is increased. However, the upper flammability limit can increase substantially as pressure increases. The graph below shows the effect of pressure on the flammability range of methane in air. While these trends are consistent for all hydrocarbons, each fuel has a different flammability ... WebFeb 15, 2024 · In the pure methane scenario, the flammability limit for methane is 9%–17%, and the VDP region is 9%–15%. Compared with the pure methane scenario, the flammability limit range in the methane and liquid coexistence scenarios is increased, which also increases the risk of explosion.

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.
