Flammability limit methane
WebNov 1, 2024 · The explosion limits of methane in air were measured at the atmospheric pressure and ambient temperature in the previous works [17,18]. 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%. WebA mixture of liquid fuels (propane 56%, acetylene 29%, methane 15%) is stored in room C. At a room temperature of 4 0 ∘ C, the vapour pressure of the fuel mixture would be 200 mmHg. What is the lower flammability limit (LFL) of the mixture? Assume percentage of each liquid fuel in the mixture remains the same in vapour state.

WebAtmospheres with a concentration of flammable vapors at or above 10 percent of the lower explosive limit (LEL) are considered hazardous when located in confined spaces. However, atmospheres with flammable vapors below 10 percent of the LEL are not necessarily safe. Such atmospheres are too lean to burn. WebThe Lower explosive limit of Methane is 5% volume in air and the Upper explosive limit is 17% volume in air. Hence, when the volume percentage of methane in an environment falls between 5% to 17%, the environmental condition is highly hazardous. The range of 5% to 17% is the explosive range for methane gas.
