WebDec 15, 2024 · Thus, blends that have flammability index ranging between 0 and 1 are flammable, whilst those with lower flammability indexes of 0 or higher than 1 are non-flammable. Thus, any blend can be evaluated as regards its flammability index, which can assume positive or negative values. 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).

WebFlammability is a measure of the extent to which a vapor concentration of a fuel in a mixture ignites and propagates a flame. The limits of flammability for a gas or vapor are the minimum and maximum fuel concentrations that can support flame propagation. WebFlammability limit describes the minimal level of mixture of air to vapors below which a flame will not burn. A mixture of air and vapors below the flammability limit means that the mixture is too lean and therefore will not burn. Consider how a carburetor works in a car. The flammability limits of gasoline are 1.4–7.5%.
