Flammability triangle methane
WebA series of experiments was carried out to determine the upper and lower flammability limits (UFL and LFL, respectively), and the explosive risk value for different mixtures of CH 4 and C 3 H 8. The critical oxygen concentration, the concentrations of CH 4 and N 2 at the point where the LFL and UFL merge, and the CH 4 explosive triangle were ... WebFigure 1: Fire Triangle – The three requirements for a fuel vapor fire to occur. A schematic of the LFL and UFL concepts for hydrogen and methane fuels is given in Figure 2. For example, when the methane content in a mixture of methane and air is below 5% (by volume) there is too little methane (too much air) present to propagate a flame
