Flammability triangle methane

WebFlammability limits of CH 4 /H 2 /air mixtures are investigated experimentally and computationally using different configurations such as a flame tube and a bomb, by Van den Schoor et al. (2008). Table 3.1 presents the measured LFL and UFL for different fuel compositions. One can see that addition of H 2 enlarges the flammability limits. This … WebIt clearly shows that if methane concentration is less than 5% or oxygen concentration is less than 12%, the mixture cannot be flammable. Mixtures containing more than 14.5% methane can become explosive if mixed with air. The flammable/explosive mixture is shown as a triangle. Sign in to download full-size image Figure 23.1.
