摘　　要：顺酐工业尾气主要成分包括正丁烷、甲烷、氢气等,常用热氧化法处理,其燃烧转化率是焚烧炉设计的关键。基于质量平衡构建替代组分对复杂反应过程进行简化,并引入相应的正丁烷、甲烷等总包反应机理对低当量比反应与输运过程进行了数值模拟。计算结果表明:设计工况条件焚烧炉中局部最高温度达1473 K,顺酐尾气中的主要可燃组分的转化率基本超过99%。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 1473 K,and the conversion rates of the major combustible components in the anhydride exhaust gas were generally above 99%.
