Flammability diagram air line
WebA flammability diagram shows the flammability region in mixtures of fuel, oxidant (usually oxygen) and an inert gas (usually nitrogen). If the oxidant concentration is reduced, the range of flammability is also reduced i.e. the difference between the upper explosible limit and lower explosible limit becomes smaller. Web2.4.4 Ternary Flammability Diagram. The major problem of a diluted flammability diagram is that it is difficult to demonstrate the dilution and purge processes (not a straight line), as composite parameters are used. A ternaryflammability diagram was proposed [43] and gained a popular position in industry for guiding dilution and purge operations.

WebHow do you read a flammability diagram? As the intersection of the flammability zone boundary with the air line. Here, ‘z’ represents the stoichiometric coefficient for oxygen. The stoichiometric line is drawn from this point to the pure nitrogen apex. The LOC is the line that shows any gas mixture containing oxygen below the LOC is not flammable. WebApr 28, 2012 · Most flammable materials demonstrate a flammability zone (the shaded area in Figure 5) — that is, a region within which the mixture is flam- mable at all …
WebJan 1, 2015 · Within theoretical flammability diagrams, two types of flammability problems can be solved. Type I problems cover flexible oxygen levels in a closed domain, while type II problems deal with fuel streams in a fixed background. For chemical engineering, purge and dilution are conventional approaches for mixture safety.
