This article presents an analysis of the validity of using catalytic additives for combustion with wood pellets in a low-power boiler. Five different catalytic additives have been used in the research, the chemical composition of which based on TiO2, MnO2, aqueous H2PtCl6 solution and 99.5% pure aqueous urea solution. The carrier for the active substance has been sodium aluminosilicate. The catalytic additive has been applied until the appropriate concentration in the pellet structure has been obtained, corresponding to 0.1% in relation to the weight of the fuel burned. Based on the results of the measurements, the percentage reduction of pollutant emissions into the atmosphere (CO, NOx, SO2 and particulate matter) and fuel consumption resulting from the use of individual active substances have been determined. The manuscript also showed the effect of the savings in fuel consumption and the unit cost of the catalytic additive on the amount of annual avoided costs for heating and domestic hot water preparation.
