【Abstract】 The main components of industrial exhaust gas from anhydride production include n-butane, methane,hydrogen, etc. It is commonly treated using thermal oxidation, where the combustion conversion rate is a key factor in furnace design. Based on mass balance, the complex reaction process of substitute components was simplified, and corresponding overall reaction mechanisms for n-butane, methane, etc., were introduced to numerically simulate the low equivalence ratio reaction and transport processes. The computational results showed that under the designed operating conditions, the local highest temperature in the incinerator reached 1 473 K, and the conversion rates of the major combustible components in the anhydride exhaust gas were generally above 99%.更多还原
