AB - This paper presents the findings of research into combustion of vegetable  oils in the composition of coal liquid fuel. The aim of the research was to  studies the influence of additives of typical vegetable oils (rapeseed,  olive, coconut oil, etc.) on concentrations of anthropogenic emissions  during combustion of coal water slurries based on coal processing waste. In  order to study the effect of different parameters on the emissions  efficiency, the tests were done in different operating conditions: muffle  furnace temperature, share of oil (up to 15%) in the mixtures and oil type.  The differences between the concentrations of sulfur and nitrogen oxides in  the combustion of typical filter cakes (waste coal), as well as those of  suspensions with the addition of vegetable impurities have been  investigated. It is shown that the concentrations of SOx can be reduced by  5-63% and those of NOx - by 5-62% in comparison with coal liquid fuels based  on oil refinery waste. Using the generalizing criterion, the paper  illustrates the advantages of adding vegetable oils to enhance the prospects  of slurry fuels (even based on waste coals) in comparison with coal that is  the most dangerous in terms of environmental pollution.
