Abstracts:

Аn experimental setup was developed as part of the task to determine the values of the thermal conductivity of coal-water slurries prepared from different grades of coal. The experimental data were processed by combining the comparison method and the numerical solution of the inverse heat conduction problem. For the processing of the experimental data a mathematical model of the experimental setup was created. It allows to calculate the distribution of temperature fields in the transient regime. Experimental studies were carried out for coal-water slurries produced from coals of different stages of metamorphism, containing high amounts of mineral impurities. As shown by experimental studies, the coefficient of thermal conductivity of coal-water slurry increases sharply compared to coal and varies from 0.41 to 0.81 W / m∙K, naturally increasing as the temperature increases in the tested range of 40-150 °C.
