WebFeb 1, 2024 · Effect of the mixture on the flammability limit and flammability limit range of methane in air. When mixed gas is added, the LFL of CH 4 is between 3.1 % and 4.95 %, and the UFL is between 14.55 % and 15.05 %. The lower flammability limit of methane is obviously reduced, such that low concentrations of methane are more likely to explode … 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 ...
