The use of renewable energy sources brings great benefits. The interest in biomass is growing, because conventional energy significantly burdens the environment, and the resources of fossil fuels are rapidly decreasing. Excess cereal grains or grains that do not meet quality requirements can be used to produce energy. For this reason, the aim of the study was to conduct research and evaluation of the use of poaceae seed grains for energy purposes. Following seeds of cereals have been subjected for testing: wheat, rye, triticale, barley and oats. Samples of cereal grains were grinded at a multi-roller mill using three different sets of rollers (number of grooves on rollers: 154, 310 and 440). The obtained material was subjected to granulometric analysis using digital image processing and energy verification for crushing purposes, and then calcined in a laboratory furnace to obtain combustion parameters. Due to the implementation of the above-mentioned research, the possibility of using poaceae seed grains for energy purposes was assessed and it was established which of the biomass types in question has the best parameters.
