The presented contribution deals with the quantification of moisture, combustible matter content, ash content and higher heating value of the selected types of biomass used for the heat production by direct combustion. The moisture, combustible matter, and ash contents were determined by gravimetric analysis in accordance with the established standards. The average moisture of the materials examined varied from 4.35 to 9.17%; the combustible matter content in the original samples ranged from 79.46 to 93.51%; the ash content ranged from 2.14 to 11.28%. Higher heating values of the examined types of biomass varied from 14,996 to 17,641 kJ/kg. The main contribution of the thesis is the acquisition of values usable in subsequent theoretical and practical efforts to increase the efficiency of the heat production by direct combustion of biomass. The results are useable in biomass boiler design and in identifying suitable conditions for combustion, including the service parameters of biomass boilers.
