Abstract

This study experimentally and numerically investigates the reaction mechanism of NO reduction during reburning using dimethyl ether (DME) as the fuel. The experiments are conducted in a quartz reaction tube at barometric pressure in the temperature range of 800-1400 K, while detailed reaction paths with 73 species and 518 reversible reactions are accounted for by a kinetic study. The numerical results are in reasonably good agreement with the experimental results. The model predictions indicate that HCCO plays a principal role in NO reduction, while HCCO plays a minor role in DME decomposition. The most important reactions for NO reduction are HCCO + NO → HCN + CO₂ and NCO + NO → N₂ + CO₂.
