利用TG-FTIR研究红霉素过期药渣与烟煤共燃烧过程热动力学模型及逸出气体产物。在40种固相反应机制函数模型中，采用双等双步法推断共燃烧过程的最佳反应机理模型，结果表明，红霉素过期药渣、烟煤单独燃烧主反应阶段最优固相反应模型分别是相边界收缩球体反应模型、随机成核随后生长模型(n＝3/4)。红霉素过期药渣与烟煤共燃烧过程中，添加比例不大于30%的物质，反应阶段动力学模型相对应于此物质单独燃烧动力学模型发生改变，而另一种物质反应模型与单独燃烧反应模型相似，但反应级数发生改变，表明共燃烧过程中两种物质存在相互影响。红外分析表明，温度达到245,℃以上，混合物中药渣熔融部分挥发产生醇、醛、酮、羧酸、酯等有机化合物；温度达到300,℃以上，燃烧过程中主要产生 CO2、CO 气体；气体产物中未完全燃烧的气体成分随药渣添加比例的增加呈增长趋势。

TG-FTIR analysis technology was applied to analyze the thermal dynamicsmodel of combustion process and the evolved gas of bituminous coal,erythromycin expired dregs and their mixtures. Double equal double step method was used to decide the best reaction mechanism model of combustion process from 40 solid-phase reaction mechanism function models. The results show that the optimal solid phase reaction models at main reaction stageof erythromycin expired dregs and bituminous coal in their separate combustion processesare spherical contraction phase boundary reaction model and random nucleation followed by growth model(n=3/4),respectively. In the co-combustion of erythromycin expired dregs and bituminous coal,when the ratio of the added substance is equal to or less than 30%,the reaction stage kinetic model is changed compared with the combustion kinetics model when the substance burns alone,while the combustion reaction model of the other substance is similar to that of its separate combustion,but with different reaction order,which indicates that there is some interaction between the two sub-stances in their co-combustion. Infrared analysis shows that when the temperature is above 245,℃,alcohols, aldehydes,ketones,carboxylic acids,esters and other organic compounds are produced due to the melting and volatilization of erythromycin expired dregs in the mixture,that when the temperature reaches 300℃ and above, CO2 and CO are mainly produced in the combustion process,and that the uncombusted compositions increase with the increased proportion of added dregs.
