为研究不同油茶壳配比对油茶壳与油页岩混样燃烧的影响，利用热重分析技术对不同配比混样进行了燃烧实验和分析。研究发现，随着油茶壳配比的增大，混样前期失重速率提高，燃烧剧烈，燃烧后期的质量残留愈少。对不同配比混合物燃烧特性参数进行了确定，发现随着油茶壳配比增大，综合燃烧指数随之提高，油茶壳单样的综合燃烧指数最高，为1.5556×10−6min−2℃−3。采用Flynn-Wall-Ozawa（FWO）法对不同配比混合物进行了动力学计算，得到油茶壳平均活化能均低于油页岩，平均表观活化能与油茶壳的比例并不存在一定的线性关系。利用傅里叶变换红外光谱仪对油茶壳和油页岩的燃烧进行了气体产物或官能团红外分析，发现主要燃烧气体产物CO、CO2吸收峰随油茶壳含量的增加而显著增强，并且吸收峰曲线向低温侧偏移，证实了混合油茶壳对于提高油页岩燃烧性能的促进作用；油茶壳比例达到50％后整体SO2的吸收峰均比较小，有利于污染物气体排放的控制。

In order to study the effect of different ratio of camellia oleifera shell on mixed sample combustion, combustion experiment and analysis of the mixture under different blending ratio of camellia oleifera shell and oil shale were carried out by thermogravimetric analysis. It was found that the weight loss rate increased with the increase of the ratio of camellia oleifera shell, the more severe the combustion, the less the quality residue in the later stage. The combustion characteristics of mixture were calculated, it was found that with the increase of the proportion of camellia oleifera shell, the integrated combustion index increased, the integrated combustion index of camellia oleifera shell was the highest, which was 1.5556×10−6min−2oC−3.The FWO method was used to calculate the dynamic calculation of the mixture of different proportions. The average activation energy of oil shale was higher than that of camellia oleifera shell. The average apparent activation energy and the ratio of camellia oleifera shell does not exist a certain linear relationship. The combustion of camellia oleifera shell and oil shale was analyzed by gas product or functional group infrared spectroscopy, it was found that the absorption peaks of CO and CO2 of the main combustion gas products were significantly increased with the increase of the content of camellia oleifera shell, and the absorption peak curve shifts to the low temperature side confirmed that the mixing of camellia oleifera shell to improve the combustion performance of oil shale advantage, the overall absorption peak of SO2 is relatively smaller when the blend ratio is more than 50%, it is conducive to the control of pollutant gas emissions.
