• Abstract in English: Combustion is the most advanced and proven method on the market for usingagricultural by-product residues and waste from the agri-food industry. Currently, a widerange of combustion technologies is used to produce heat and electricity in low-powerheating devices (>50 kW) using various types of biofuels from biomass (woody biomass,herbaceous biomass, waste and residues from the agri-food industry). Combustion ofbiomass fuels, especially those of wood origin, causes lower carbon dioxide (CO2) andsulfur oxides (SOx) emissions into the atmosphere compared to coal combustion. Thegrowing interest in solid biofuels has contributed to intensive activities on improving thecombustion process and energy devices enabling effective and economic conversion ofchemical energy contained in biomass into other usable forms such as heat, electricity.Having good quality fuel, it is necessary to ensure an appropriate, clean combustiontechnique, which allows to achieve the highest thermal efficiency of the heating device andat the same time the lowest emission of pollutants. The article presents issues related tothe theory, characteristics of the combustion process and problems related to the formationof harmful chemical compounds nitrogen oxides (NOx), SOx, carbon monoxide (CO),particulate matter (PM) emitted to the atmosphere during the combustion process in low-power heating devices. The analysis indicates the possibility of minimizing undesirablephenomena during the combustion of these biofuels related to ash sintering, the formationof deposits, corrosion and improving the amount of condensable solid particles formedand therefore reducing the emission of gaseous products to the environment.
