The outcome of these researches shows that the LFL (the lower flammability limit) of methane is 4.6 ± 0.5%, while the UFL (the upper flammability limit) of methane is 15.8 ± 0.4%.
WebJun 15, 2024 · Flammable hazard distances are often defined by the distances to half of the lower flammability limits (LFL) (or sometime to LFL) of the released gas mixtures in air, and they are often calculated accordingly. ... 25 kg/s, 30 kg/s and 45 kg/s. The LNG vapour was assumed to have the physical properties of methane at a molecular weight of 17.2 ... Triangular diagrams are not commonplace. The easiest way to understand them is to briefly go through three basic steps in their construction. 1. Consider the first triangular diagram below, which shows all possible mixtures of methane, oxygen and nitrogen. Air is a mixture of about 21 volume percent oxygen, and 79 volume percent inerts (nitrogen). Any mixture of methane and air will therefore lie on the straight line between p…
