A model for predicting temperature effect on flammability limits

A model for predicting the variation of flammability limits by the initial temperature was derived from the energy balance equation. All parameters of this proposed model can be sourced from the literature and do not need to be regressed by any experimental data. The proposed model was validated using 20 sets of experimental data consisting of 11 compounds, including alkanes, alkenes, alcohols, a ketone, an ester and inorganic fuels. Some samples were measured experimentally and other sample data were adopted from the literature. Overall, the proposed model predicted the temperature variation data of the flammability limits well when based on the adiabatic assumption. Application of this model is not restricted to organic fuels, but also inorganic fuels, such as carbon monoxide and hydrogen.
