Abstract

The main physicochemical coefficients of the components and of the tested coal-water slurry containing petrochemicals (CWSP) have been collected. The viscosity, mixture stability, density, ash content, humidity, flash and ignition temperatures, and enthalpy of combustion of the tested CWSP are reported. The temperatures of combustion of fuel compositions with different concentrations of solid and liquid components have been measured, as well as the important parameters: the ignition time delays of droplets (radius 0.25-2.5 mm) and the times required to reach their complete burning. The study allows determination of the optimal fuel compositions yielding the shortest ignition time delays, the longest times to complete burning, the highest temperatures of combustion, and the maximum enthalpy of combustion. It is found that the viscosity of CWSP is dependent almost proportionally on the moisture content of components. It is shown that the calorific value of CWSP is dependent proportionally on the calorific value of components. It is revealed that the ignition delay times of CWSP are dependent significantly on the degree of coal metamorphism and the volatiles content, as well as on the heat of vaporization and the boiling point of added flammable liquids. Important experimental data are obtained, which allow prediction of the CWSP composition with the desired properties of components, for which the following characteristics are known: calorific value, moisture content, ash content, volatile content, heat of vaporization, boiling point, and other characteristics considered.
