Abstract. Biomass combustion has a huge potential to produce heat and power in a sustainable way. However, some biomass fuels, like grass and straw, have problems with ash melting behaviour. This is due to the chemical composition of biomass ash, particularly the presence of potassium, which reacts with other ash forming elements (Si, P and others) and lead to different ash related operational problems. Utilization of additives can abate these problems. This work deals with using of different additives in biomass to abate problems with ash slagging and melting. As additives were used kaolin, talc, limestone, lime, dolomite, bentonite. Additives were added to wood sawdust in amount 2 percent and were pelleted. It was tested effect of additives on abrasion resistance, total heating value, ash content, ash melting temperature and sinter degree in ash of made wood pellets. Based on the obtained results positive effect on ash melting behaviour was showed with using of all used additives except bentonite
