Effect of trimethylphosphate additives on the flammability concentration limits of premixed methane-air mixtures
- 38 Downloads
The effect of small additives of trimethylphosphate (TMP) on the lean and rich flammability concentration limits of CH4/air gas mixtures were studied using an opposed-flow burner and numerical modeling based on detailed kinetic mechanisms. TMP was found to narrow the flammability concentration limits of premixed CH4/air mixtures. Modeling using a previously developed model for flame inhibition by phosphorus compounds showed that the model provides a satisfactory fit to experimental results on the effect of TMP additives on the lean concentration limit.
