Taking heat generation as the evaluation index,the orthogonal experiment was used to optimize the combustion conditions of blending municipal sludge and cotton stalks.The result showed that the pri-mary and secondary factors affecting the heat generation of the sludge mixture were cotton stalks blending ratio＞stirring time＞particle size of blending,and the optimal blending conditions were 40％of cotton stalks blending,stirring time of 5 min,and blending particle size of 0.075 mm.Under optimal mixing con-ditions,the ignition and combustion temperatures of urban sludge were significantly reduced,the heat gen-eration was increased by 34％,the comprehensive combustion characteristic index was increased by 3.97 times,the activation energy was reduced by 12.74 kJ/mol,and the sludge and cotton stalks were in the stage of positive facilitation in the combustion process almost the whole time.
