Sažetak
The production of fuel pellets from biomass has become a significant economic activity in the world. Energy from biomass has multiple environmental benefits in comparison to other fuels, while its use requires minimal modifications of system used in the combustion of fossil fuels. The increase of the production capacity influences the increase of the need for biomass. Great potential apart from wood lies in agricultural biomass. Agricultural residues have certain drawbacks that could be expressed as increased ash content and the difficulty pelleting process. One of the solutions for these problems is mixing agricultural and wood material. This paper analyzes eight types of agricultural residues in certain proportions mixed with fir wood biomass. Mixtures are formed in order to produce pellets of quality grade EN B which allows to 3 % of ash content in the fuel. Moisture and ash content were determined for every mixture and the results were analyzed. Since in some mixtures is determined ash content which exceeded the limit value of 3 %, adjustments of proportions were made. According to the results of the ash content analysis and available amounts of biomass it was selected optimum mixture (the share of fir-wood biomass was 70 % and of corn stem 30 %). Selected mixture was used for agro-wood pellets production using small press with horizontal die. Produced pellets were tested for determined properties according to EN ISO 17225-1: 2014.
