Abstract
The conditions and integral characteristics of stable low-temperature ignition of droplets of suspension organic water–coal fuels are established by using the means of high-speed video-detection. The oxidizer temperature for these conditions varies in the range of 600–900 K (much below the temperatures in furnace chambers of modern power installations exceeding 1200 K). The velocity of the oxidizer-flow motion varies from 0.5 to 5 m/s, and the sizes (conditional radii) of droplets vary from 0.5 to 1.5 mm. The times of initiation of burning under conditions of low-temperature heating and the duration of the complete combustion of droplets of the corresponding compositions of organic water-coal fuels are determined. The necessary and sufficient conditions of stable ignition are singled out for promising organic water–coal fuels.
