The article presents the results of experimental studies performed for the comparative analysis of factors affecting the concentration of the main gas emissions during the combustion of fuel suspensions obtained from coal enrichment waste. The factors in uencing the formation of anthropogenic emissions during the aring of coal-water fuel suspensions were investigated. Experiments were carried out with coal processing waste, both with and without additives in the form of spent mineral oil. The article shows how the concentration of sulfur dioxide, nitrogen dioxide, and hydrocarbons is affected by the parameters of preparation (particle size, solid-liquid phase ratio, additives of used engine oil) and combustion (temperature in the combustion chamber, excess air coe cient, and droplet size after spraying) of fuel suspensions.

The article presents analytical results on the use and distribution of energy in reverberatory furnaces with medium pressure gas burners to melt nickel-containing raw materials, by means of a numerical simulation of the furnace’s combustion space. The combustion flow and radiation of a reverberatory furnace powered by natural gas have been calculated and validated. The chemical composition of natural gas makes it the cleanest of fossil fuels, for this reason its use increases worldwide. The higher hydrogen/carbon ratio in its composition, compared to other fossil fuels, causes combustion to emit less CO2 per unit of energy produced. The flue gas outlet duct and medium pressure burners are represented and located as in a typical design to determine the effect on the efficiency of the reverberatory furnace. The results show the temperature field, the mass fraction of oxygen and fuel within the furnace’s combustion space and the comparison between the theoretical and practical efficiency of a furnace.
