Abstract
A skeletal mechanism of inhibition and quenching of methane flames by addition of trimethyl phosphate was developed. It includes a mechanism of methane oxidation consisting of 19 elementary steps involving 15 species (including N<sub>2</sub>), and four elementary reactions involving three phosphorus-containing species (PO<sub>2</sub>, HOPO, and HOPO<sub>2</sub>). The developed skeletal mechanism adequately predicts the burning velocity of flames with added inhibitor over a range of equivalence ratio of 0.7–1.4 and can be used to model fire suppression.
