Relevance. The problems arising in developing fuel composites and consisting in determining the optimal ratio of combustible components are solved in the study of their physicochemical and operational properties. Particular attention should be paid to ignition and combustion of the air suspension of fuel compositions. Aim. The implementation of these problems is seen in the development of an experimental technique for predicting some indicators of coals and coal waste based on the methodology of analyzing video files air suspension of ignition in the form of a graphical visualization of combustion. Methods. Technique for assessing and predicting some indicators of coals and coal waste obtained on the basis of the methodology of analyzing video files of air suspension ignition in the form of a graphical visualization of combustion. Results and conclusions. The authors have obtained the dependence of the predicted value for determining the air excess coefficient for coals and coal waste. They developed the methodology for graphical visualization of the combustion of coals and coal waste air suspension. The Kuznetsk coal of grade D was studied and its combustion was described in the case of combustion in active hydrodynamic modes. The developed method for assessing and predicting some indicators of coals and coal waste obtained on the basis of the methodology for analyzing video files of air suspension ignition in the form of graphical visualization of the combustion proved its effectiveness. It showed a good distribution of dust-coal particles in a gas-dust cloud throughout the volume, demonstrating stable and efficient combustion of the fuel system. Convective flows in the reaction chamber do not break the forming combustion front. Graphic visualization of combustion showed that during this process, there is a minimum time of destructive processes occurring in coal particles. This indicates efficient heat and mass transfer. For the studied system of Kuznetsk coal of grade D, the optimal fuel-oxidizer ratio α is 1.25. Oxidation reactions in this case occur in a shorter time, which is characterized by an increase in pressure in the reaction volume.
