Thermodynamic and kinetic parameters of co-combustion of textile dyeing sludge (TDS) and sugarcane bagasse (SB) were studied using thermogravimetric analysis in CO/O and N/O atmospheres. Our results showed that the comprehensive combustion characteristic index (CCI) of the blends was improved by 1.71-4.32 times. With the increased O concentration, co-combustion peak temperature decreased from 329.7 to 318.2 °C, with an increase in its maximum weight loss rate from 10.04 to 14.99%/min and its CCI by 1.31 times (β = 20 °C·min). To evaluate the co-combustion characteristics, thermodynamic and kinetic parameters (entropy, Gibbs free energy and enthalpy changes, and apparent activation energy) were obtained in the five atmospheres. The lowest apparent activation energy of the TB64 blend was obtained in oxy-fuel atmosphere (CO/O = 7/3).
采用热重分析法在 CO/O 和 N/O 气氛下研究了纺织染整污泥（TDS）和甘蔗渣（SB）共燃烧的热力学和动力学参数。结果表明，混合物的综合燃烧特性指数（CCI）提高了 1.71-4.32 倍。随着 O 浓度的增加，共燃烧峰温从 329.7 降至 318.2°C，最大失重率从 10.04%/min 增加到 14.99%/min，CCI 增加了 1.31 倍（β=20°C·min）。为了评估共燃烧特性，在五种气氛下获得了热力学和动力学参数（熵、吉布斯自由能和焓变以及表观活化能）。在富氧气氛（CO/O=7/3）下，TB64 混合物的表观活化能最低。
