<jats:title>Abstract</jats:title><jats:p>When it comes to the production of energy from renewable sources, biomass is the main fuel, burned directly or co-fired with coal, used in the professional power industry. As in the case of coal, the use of biomass in the professional power industry is accompanied by the generation of by-products of the combustion process, primarily in the form of fly ash. These wastes significantly differ from those resulting from coal combustion. Their properties depend primarily on the burned biomass and boiler type. Due to the growing pressure on the use of energy from renewable sources resulting from the Energy Policy of Poland and the requirements imposed by the EU, more and more by-products are produced. Ashes from the co-firing of biomass are relatively well studied, especially when it comes to those resulting from the combustion in conventional boilers. The by-products of biomass combustion are of limited economic use due to their specific characteristics. The ashes resulting from the combustion in fluidized bed boilers are particularly problematic. The paper presents the research results on the basic properties of the three ashes generated from the combustion of biomass in fluidized bed boilers and one ash resulting from the co-firing of biomass with coal in pulverized coal boiler for the same biofuel type. The conducted analysis of the chemical composition has shown a high content of CaO and CaO</jats:p>
