Using the Flammability Diagram To Avoid Flammable Atmospheres

Using the Flammability Diagram To Avoid Flammable Atmospheres [Pg.301]

One might suggest an even more optimized procedure. This involves first pumping air into the vessel until a point is reached on the air stoichiometric line above the UFL. This is followed [Pg.301]

LFL is the volume percent of fuel in air at the lower flammability limit, and z is the stoichiometric oxygen coefficient from the combustion reaction given by Equation 6-9. [Pg.303]

Another approach is to estimate the fuel concentration at point S by extending the line from point R though the intersection of the minimum oxygen concentration (M) and the stoichiometric combustion line. The analytical result is [Pg.303]
