SUMMARY Boruk S.D. Development of scientific bases for creation of environmentally acceptable dispersed fuels for power generating enterprises of Ukraine. - Qualifying scientific work on the rights of manuscripts. Dissertation for obtaining a scientific degree of Doctor of Technical Sciences in specialty 21.06.01 - ecological safety. - State Ecological Academy of Postgraduate Education and Management, Kyiv, 2018. According to the results of the work performed under this dissertation, the actual problem of development of scientific bases for the creation of environmentally acceptable dispersed fuels for energy generating enterprises of Ukraine, which takes into account the features and patterns of the influence of the species and the ratios of the components of the binary and ternary of disperse systems, degree of metamorphism and granulometric composition in coal raw materials on the properties of coal dispersed fuels, as well as the level of environmental pollution by thermal power plants in case of their application, which is a scientific basis and a prerequisite for increasing the ecological safety of thermal coal power plants and adjacent territories. The definitions of the following concepts are provided: "environmentally acceptable water-coal disperse fuel" and "environmentally acceptable technology of water-coal disperse fuels". The ingredient composition of ecologically acceptable dispersed coal fuels on the basis of coal deposits of Ukraine and coal-fired wastes containing 62.5 ± 2.5% (w / w) dispersed coal raw material, 33 ± 5% (w / w) dispersion medium (is theoretically substantiated and developed (water or organic matter), 1,5 ± 0,5% (wt) of a modifying additive (sodium lignosulfonate). It was established that the application of the proposed dispersed coal-fired hydroelectric power plants creates the preconditions for reducing the specific emissions of the main pollutants: sulfur (IV) oxide by 27.5 ± 5.5%, nitrogen for oxides by 47.5 ± 5.5%, aerosol particles per 87.5 ± 2.5%. Key words: scientific basis, ecologically acceptable dispersed water-coal fuels, environmentally acceptable technology, environment, pollution, emissions, waste and process water, ash, slag, dust, sedimentation stability, viscosity, calorific value.
