CREATION AND DEVELOPMENT OF INNOVATIVE COAL TECHNOLOGIES AT THE SIBERIAN STATE INDUSTRIAL UNIVERSITY

The article is dedicated to the anniversary of the Department of Thermal Power Engineering and Ecology (90 years). The scientific results obtained in innovative areas of technology, including with the participation of the department staff, are presented. The main studies were carried out in the experimental laboratory created during the implementation of the high-tech project "Development of technology and creation of a pilot model of an operating energy-generating complex operating on coal washing waste". Feasibility studies have been developed for the creation of a mini CHPP on coal washing waste from the washing plants of JSC «Kuzbassrazrezugol» and other southern enterprises, the transfer of coal boilers of boiler houses of washing plants (WPP) to water-coal fuel and a business plan for the creation of technological complexes for partial replacement of pulverized coal fuel with water-coal fuel prepared from southern WPP sludge at the thermal power facilities of EVRAZ ZSMK. The article presents the main technological directions developed by the Center of Innovative Coal Technologies (CICT) of SibSIU in the field of coal beneficiation and coal processing related to environmentally friendly methods of utilization of fine coal sludge (FCS) using coal-water fuel (CWF) technologies and agglomeration (briquetting), additional enrichment, oil granulation method, as well as a fundamentally new one - coal oxidation using extreme mechanomechanical and electrophysical effects on coal-water suspension chemistry. The article describes the results of development and creation of local energy sources using gasification of brown and low-metamorphosed hard coals. The possibility of utilization of environmentally friendly ash and slag waste and rock dumps of enrichment plants is shown. The developments of unique equipment of the Central Institute of High Technologies (bi-chamber vibratory mill, reactor-mixer, coarse and fine filters, pump-activator, adiabatic vortex combustion chamber, etc.) for heating and efficient combustion of coal-water fuel based on both coal and FCS are presented. Within the framework of international scientific and technical cooperation, the Institute of High Technologies of the Academy of Sciences of Heilongjiang and the Heilongjiang University of Science and Technology have been signed.
