山西省乃至全国大量煤泥和城市污泥处理面临前所未有的挑战。清洁燃烧技术是污泥-煤泥协同处理的优选方法。为探究污泥-煤泥混燃过程中的相互作用，为清洁高效燃烧利用提供依据，采用热重质谱联用技术（TG-MS），研究了污泥和煤泥单独燃烧和共燃烧过程中的燃烧特性和污染性气体产物（CH₄、CO、CO₂、NH₃、HCN、NO、NO₂、H₂S、CH₃SH、COS、SO₂、CS₂、SO₃）的析出特性，同时采用Coats-Redfern积分法对污泥和煤泥单独燃烧和共燃烧过程进行动力学特性分析，对两者的相互作用机制进行了深入探讨。结果表明：在污泥和煤泥共燃烧过程中，存在很明显的交互作用。污泥和煤泥相互促进，提高了整体的反应性能，其中煤泥掺混20%时燃烧特性最优，表明污泥比例的增加不会对燃料整体的燃烧性能造成影响。污泥和煤泥的质均活化能E_m分别为51.170 kJ/mol和78.538 kJ/mol，混燃时污泥可以降低混合样品的质均活化能E_m，协同作用使得混合样品的实际质均活化能E_m低于计算值。污泥单独燃烧时动力学模型为（D3→D4）；煤泥单独时的燃烧动力学模型为（F1）；混合样品的区间动力学模型为（D3→D1→D3/F1），表明交互作用可以改变燃烧过程中的反应机理。当煤泥掺混20%时对温室气体（319.742%）的抑制效果最好；当煤泥掺混80%时对含硫气体（636.492%）和含氮气体（534.811%）的抑制效果最好；表明相互作用对混合样品的气体生成有较大的抑制作用，其中煤泥掺混20%时对污染性气体排放总量的抑制效果最强（319.740%）。

The treatment of the large amount of coal slime and municipal sewage sludge in Shanxi Province and even the country is facing unprecedented challenges. Clean combustion technology is the preferred method for sewage sludge-coal slime co-processing. In order to explore the interaction of sludge - coal mud combustion, provide a basis for cleaning and efficient combustion utilization. This paper uses thermal heavy mass spectral (TG-MS) to study the precipitation characteristics of combustion characteristics and pollutant gas products (CH₄, CO, CO₂, NH₃, HCN, NO, NO₂, H₂S, CH₃SH, COS, SO₂, CS₂, SO₃), in the combustion and coal burning process in sludge and coal mud. At the same time, the Coats-Redfern Integral Law is used to dynamically explore the mid-combustion process of sludge and coal mud alone. The results show that there is a significant interaction in the process of coal burning in sludge and coal mud. Sludge and coal mud promote each other, improve the overall reaction performance, in which the combustion characteristics are optimal when the coal slime is blended 20%. It indicates that the increase in sludge ratio does not affect the combustion performance of the fuel overall. The Em of sludge and coal slime were 51.170 kJ/mol and 78.538 kJ/mol, sludge can reduce the average activation energy of the mixed sample, and the actual Em of the mixed sample is lower than the calculation. The kinetic model is (D3→D4) when the sludge is alone; the combustion kinetic model (F1) when the coal slime is separate, and the interval kinetic model of the mixed sample is (D3→D1→D3/F1), indicating interaction the reaction mechanism during the combustion can be changed. When the coal slime is blended 20%, the inhibition of the greenhouse body (319.742%) is preferably inhibited; when the coal slime is blended 80%, the difference (636.492%) and the inhibitory inhibition containing traditional (534.811%); indicating interaction is a great inhibitory effect on the traditional form of integrated varieties, in which the inhibitory effect of the contaminant contaminated body content is most (319.740%) when the coal slime is blended 20%.
