Flammability range of methane
WebAlthough the lower flammable limits (LFLs) are well defined for methane (CH,) and Propane (CA), the LFLs for hydrogen (HZ) and its heavier isotope deuterium (D2) are … 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 ...
