EXPERIMENTAL RESEARCHES OF THE EFFECT OF VEGETABLE OIL ADDITION ON THE EMISSIONS DURING COMBUSTION OF COAL LIQUID FUELS

ABSTRACT
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.
