Propagation velocity of hydrocarbon-air flames containing organophosphorus compounds at atmospheric pressure

The propagation velocities of propane-air and methane-air flames of various compositions with and without the addition of 600 ppm trimethyl phosphate were measured and calculated. The flame propagation velocity was determined using the heat flux method, which allows a flame to be stabilized on a flat burner under nearly adiabatic conditions. The experimental results were compared with flame propagation velocities calculated using the PREMIX and CHEMKIN codes for the Westbrook mechanism for the destruction of trimethyl phosphate and the Curran mechanism for hydrocarbon oxidation. The methane-air flame was modeled using the GRI 3.0 mechanism.
