Estimation of lower flammability limits of CH compounds in air at atmospheric pressure, evaluation of temperature dependence and diluent effect

Determination of lower flammability limits of C–H–O compounds in air and study of initial temperature dependence

“…Considering that T LFL does not change when the mixture's initial temperature changes is equivalent to assuming that n is equal to zero for any initial temperature. In published studies (Zabetakis, 1965;Zlochower, 2012;Mendiburu et al, 2015), that consideration had accurate results for methane, propane, iso-butane, ethylene, propylene, carbon monoxide, ammonia, and dimethyl ether. However this is not true for all compounds, as can be observed on Figs.…”

“…In earlier work, Mendiburu et al (2015) studied the case of C-H compounds. For these compounds, adiabatic flame temperature at the LFL could reliably be assumed to be constant.…”

Determination of upper flammability limits of C H O compounds in air at reference temperature and atmospheric pressure

“…In this sense, the method is similar to those based on the calculated adiabatic flame temperature that were developed for the determination of the LFL [17,18]. Also among these works, those by Rowley et al [19] and Mendiburu et al [20,16] can be considered.…”

“…Mendiburu et al [14] developed a semi-empirical method based on adiabatic flame temperature and chemical equilibrium. The method determines the UFL of CAH compounds in air at atmospheric pressure and reference temperature.…”

Flammability limits temperature dependence of pure compounds in air at atmospheric pressure

“…Most of the methods available in the literature were developed to determine the LFLs, such as the works of Catoire and Nauder [3], Rowley et al [4], Britton [5], Britton and Frurip [6], Mendiburu et al [7], Zlochower [8], Mendiburu et al [9] and Liaw and Chen [10]. Fewer studies are devoted to determine the UFLs at different initial temperatures, among them the works of Mendiburu et al [11] and Liaw and Chen [10].…”
