Tóm tắt:	Title screen The low reactivity of coal processing wastes (filter cakes), petroleum derivatives, oil sludge, oil-wateremulsions, coal-water suspensions, as well as used fuel and industrial oils is the main barrier to theircommon use as main fuel on thermal power stations and a boiler plants. It leads to high energy consumptionfor heating the combustion chambers and subsequent firing. In this work, we suggest usingsawdust as an additive to intensify the heating and ignition of coal water slurries containing petrochemicals(CWSP) prepared from coal and oil wastes. We show that adding even 10% sawdust lowers thethreshold temperature of sustainable ignition by as much as 70e80 K. The more volatiles are in coalprocessing wastes, the more noticeable the contribution of sawdust to the intensity of CWSP ignition. Therole of sawdust as an ignition intensifier is found to increase significantly with the rising CWSP dropletsize and air temperature. Replacing the coal component (e.g., filter cake) of the CWSP composition bysawdust of the same mass leads to a negligible change in the calorific value of the fuel. At the same time,the anthropogenic emissions of nitrogen and sulfur oxides are reduced considerably Режим доступа: по договору с организацией-держателем ресурса
