Investigation of the elemental and technical composition and thermophysical properties of coal samples from the Talovsky deposit of Siberia

The work is devoted to the study of thermophysical properties, elemental and technical composition of brown coal of the Talovskoe deposit in Siberia. This kind of coal can be used as power fuel for thermal power plants, boilers, etc. However, according to the preliminary analysis, this type of fuel requires additional processing, namely activation, drying, crushing, enrichment, removing toxic impurities, etc. From the available known methods of coal processing, one of the most promising and innovative technology may be exposure of coal to microwave radiation. With this treatment, intense drying of the material, grinding, yield of nitrogen, sulfur and other toxic components during processing takes place. This significantly increases the energy efficiency and environmental friendliness of the further use, of the final product processed in this way. Design and efficient engineering systems for heating, drying, grinding and using microwave energy requires a more in-depth information about the parameters of this type of coal and the changes in the course of technological processes. This work aimes at finding and studying such regularities for brown coal of the Talovskoye field. (paper)
