Abstract

This paper provides the research results of technological-technical means and operations for solid biofuel preparation: chopping, milling, pelleting and burning of fibrous plants – 3 sorts of seeder hemp (“Epsilon 68”,”Beniko” and “Bialobrzeskie”). These energy plants were grown in the experimental fields of Lithuanian Research Centre for Agriculture and Forestry, Upytė Experimen-tal Station, and in Aleksandras Stulginskis University were investigated the technical means of the-se plants preparation and usage for energy purposes. It was investigated the technique for plant milling and were determined seeder hemp mill fractional composition while usage the hummer miller prepared mill. Produced mill was used for pellet production and there were determined the seeder hemp pellet quality indicators – moisture content and bulk density. The fibre plant pellet moisture content ranged from 6.4 % to 8.8 %, and pellet density reached 1082.7–1186.2 kg m-3 DM (dry matter). Determined net calorific value of seeder hemp dry mass was relatively high (17.2–17.5 MJ kg-1), it was close to calorific value of some wood species.
