摘要: Abstract This paper presents an assessment of the energetic and mechanical properties pellets produced from agricultural biomass. For production following raw materials were used: wheat straw, rape maize straw. Additionally, mixtures wheat-rape wheat-maize rape-maize straw (each accounting for 50% mass) applied. The studied resources ground with use a universal shredder driven by 7.5 kW electric engine. A pelleting machine fitted fixed flat matrix two thickening rolls was used to produce pellets. Analyses moisture calorific value as well bulk density strength performed according biding standards. ranged 16.5% 18.5% respectively. average fluctuated between 15.3 MJ kg −1 mixture 16.2 MJ kg depended on type used. lowest recorded (386–420 kg m −3 ), highest (561–572 kg m ) noted (95.4–96.8%), whereas made (96.8–98.9%).
