Аннотация: The combustion processes of brown coal, wood biomass, cardboard, and their mixtures in an oxidizing atmosphere at a heating rate of 20 K/min were studied within the framework of synchronous thermal analysis. The curves of weight loss and differential scanning calorimetry were obtained to describe the combustion processes of individual fuels and solid fuel mixtures with a weight ratio of 50 : 50. The main process parameters of combustion, such as ignition and burnout temperatures and a maximum rate of reaction were determined using analytical and numerical methods. The combustion indices of the fuels and their mixtures were established, and the kinetic parameters of the test processes were calculated. Based on the differential weight loss data, the nature of interactions between fuel mixture components was determined. The high volatile content of wood sawdust and cardboard affected a decrease in the ignition temperature of the mixtures by 15–18%, as compared to that of brown coal. The burning temperature of a mixture with the addition of wood sawdust decreased by 6.5%, and the addition of cardboard affected an increase in the burning temperature of the mixture by 27%.
