Ignition and Combustion of Mixed Fuels Based on Coal and Wood under Different Conditions of Thermal Influence

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 was established that the concentration of a wood component had a significant impact on the processes of the onset of oxidation and combustion of the mixed fuels. When the fraction of wood component in the mixture was increased to 50%, the ignition delay time decreased by an average of 18% in all cases of the studies performed.
