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. 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.
