Abstract
The objectives of study were to investigate the ash content, carbon content and the higher heating value and modelling of HHV of forest and agricultural biomass. Five types of biomass were used for the experiments: sunflower husk pellets, wood pellets, straw and hay briquettes, and forest chips. The investigated biomass properties (their average values) change: for ash content between 1.3% (woods pellets) and 7.3% (hay briquettes), for carbon content between 37.4% (forest chips) and 52.0% (wood pellets), for HHV between 14.8 kJ/kg (forest chips) and 20.1 kJ/kg (sunflower husk pellets). Two mathematical models from literature and model proposed by the authors were used to the HHV calculation. The model proposed by the authors gave the best results in determination of sunflower husk pellets HHV.
Highlights
One of the most important global problem nowadays is the worldwide energy crisis connected with decreasing fossil fuel resources but with global climate changes as well [1,2]

Obtained values of ash content are slightly different that reported in the literature [17,18]
Summary
One of the most important global problem nowadays is the worldwide energy crisis connected with decreasing fossil fuel resources but with global climate changes as well [1,2]. Biomass is one of discussed energy sources. All biologically produced matter such as forest and agricultural residues, energy crops and wood is described by term of biomass [4,5]. Biomass in contract to fossil fuels, can be regarded as CO2 - neutral fuel, because it absorbs almost the same amount of CO2 from atmosphere during photosynthesis as it releases when used as a fuel. For these reason, biomass is energy source that reduces greenhouse gases [3,6]
