WebHydrogen's flammability range (between 4% and 75% in air) is very wide compared to other fuels, as shown in Figure 3. Under the optimal combustion condition (a 29% hydrogen-to-air volume ratio), the energy required to initiate hydrogen combustion is much lower than that required for other common fuels (e.g., a small spark will ignite it), as … WebJul 11, 2005 · methane, 12; propane, 11.5; ethylene oxide, 0; benzene, 11.4; toluene, 9.5; ... Flammable limits get closer together as the temperature goes up towards the Auto Ignition temp and get a little fuzzy close the the AIT. However, if the air is always ambient, the gas temperature itself has less of an effect. ... 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… thomas kenneth plofchan iii family tree
