Abstract
AbstractThe results of spraying characteristics of alcohol‐coal‐water slurries are presented. It has been experimentally proved that the lowest viscosity value of the studied slurries varies from 54 to 329 mPa s. The density value of alcohol‐coal‐water slurries decreases to 1130 kg m−3 when the content of isopropyl alcohol in the fuel composition is 8 wt %. The largest value of jet spraying angle corresponds to alcohol‐coal‐water fuel with an isopropyl alcohol content of 8 wt %. The number of sufficiently large droplets decreases in comparison with a typical two‐component coal‐water fuel. The calorific value of alcohol‐coal‐water slurries rises when the third liquid fuel component is introduced into the composition of coal‐water fuel.
