Influence of petrochemicals on jet characteristics after coal-water fuel spraying

Research output: Contribution to journalArticlepeer-review

Abstract

Application of liquid waste of industrial rubber goods (IRG) and waste car oil (WCO) as an additional component of coal-water fuel (CWF) was experimentally studied. It has been established that efficient introduction of liquid combustible components (LCC) into coal-water fuel prepared on the basis of long-flame coal is possible, if their concentrations in the studied slurries do not exceed 8% by weight. A further increase in the concentration of the third component causes an increase in the fuels viscosity, which significantly worsens the jet characteristics after spraying. Increase in the jet spraying angle is about 25%, but a significant number of inhomogeneities and large fragments appear in its composition. Introduction of the third component into the composition of coal-water fuel allows increasing its calorific value by 9.9–31.1%.
