Abstract

The ignition processes of mixed fuels formed on the basis of grade 3B coal from the Maikuben deposit and finely dispersed sawmill and woodworking waste have been studied. An analysis of the processes of ignition and combustion of fuel mixtures with different organization of combustion processes was performed. It has been established that the concentration of the wood component has a significant impact on the processes of the onset of oxidation and combustion of mixed fuels. When the proportion of wood component in the mixture increases to 50%, the ignition delay time decreases by an average of 18% in all cases of the studies performed.
