Abstract

We investigate the macroscopic laws of variation of inertial heating and ignition conditions for composite liquid fuel droplets in an oxidant flow (air) by the special-purpose heating experimental equipment. Composite liquid fuel has been the conversion waste of the coal of rank K (Berezovskii field in Kemerovo region, Russia) and T (Kaltan coal pit in Kemerovo region, Russia), water, scavenge synthetic engine oil and fine particles of the dressed coal of relevant ranks. Further, we study the macroscopic laws of the inertial heating of a composite liquid fuel droplet boundary layer, thermal decomposition of the organic part, yield of volatiles and liquid combustible component evaporation, ignition of gaseous products and carbon residual of coal particles. Investigations demonstrate that the increase of dressed coal concentration in the composite liquid fuel leads to a significant reduction of expenses for the ignition (delay times shorten by 10-15%) of fuel composition.
