Summary:Title screen
Industrial combustion of waste and non-conventional mixtures requires a broad database of important fuel characteristics that determine process efficiency. In this work, individual components (such as coal waste, coal, biomass) and composite fuels were analyzed to obtain the dependencies between ignition delay time and key fuel properties. The analysis revealed the need to select experimental data to obtain empirical formulas. In particular, micro-explosive breakup ensured a significant decrease in the ignition delay time (by 60% or more). For other cases, a minimum scale of influence of the following factors was established: an increase in the moisture content in the range of 2–40% led to an increase in the ignition delay by 50%; an increase in the proportion of volatiles from 5% to 60% accelerated fuel ignition by 50%. The highest coefficient of determination was demonstrated by the empirical dependence of the ignition delay time on the fuel volatile to moisture ratio. With an increase in this ratio from 0.25 to 15, the ignition delay time decreased by 2–2.5 times. The results are aimed at simplifying engineering assessments and adapting energy facilities to waste and low-grade fuel combustion
