| Resumo: | Title screen The purpose of this work is to experimentally determine conditions and characteristics of floating particles ignition of fuel mixtures based on coal dust with characteristic sizes of less than 80 µm and fine wood (typical sizes up to 200 µm) at various mass concentrations of fuel components. The experiments were conducted in a medium heated to high temperatures of still air (from 600 °C to 1200 °C). Record of the processes of heating of the researched fuel mixture that is quite promising for heat power engineering, their subsequent ignition and combustion was performed by a high-speed video camera (image format - 1024 Ч 1024 pixels, frame rate - up to 105 per second). It has been established that increase in the proportion of relatively large particles (compared to coal) of the wood component in the fuel mixture does not significantly affect the values of ignition delay times of all investigated wood-coal mixtures based on two typical grades of coal (long-flame and lean).
