Abstract: For a longtime the country's energy sector leading positions belonged to fossil fuels – gas and oil but now it is time to give positions for biofuels. The latter source is one of the types of alterna-tive renewable energy resources. Geographical situation of Lithuania highly conducive to the use of biofuels, because of a large area of the country shall bear in the woods and scrub. Solid biofuels can be used directly or processed state (briquettes, pellets, dust) [1]. The most important agricultu-ral crops are considered as sources of biomass, however, on the basis of the data of the Department of statistics of Lithuania, Lithuania is about 300-500 annually acres of farmland. Highlighting the importance of biomass these areas could be used for the production of biomass for perennial herbs or other less-discerning plants.On the basis of current data, it is predicted that by 2020-2025 year 75% of the heat even in the district heating sector, will be made from local resources, household will make up 90%. Lithuania's preparation of bio fuels currently is collected about 130-140 thousand tons of straw. The largest part of the straw is used for the production of pellets.Pellet production technolo-gy and equipment depends on the composition of the raw material, raw material and moisture for the fractional. The production of pellets and briquettes production, allow thicken straw from 150-250 kg/m3 up to 600 kg/m3, thus increasing the amount of energy per unit of volume, and by redu-cing the necessary storage areas.At the time of granulation beads sharp heats up and the moisture from the contained therein after the outbreak of the granulation bead must be cooled, however, after it is necessary to granulation the cooling technology, as a result, this process make an impor-tant role so it has to be analyzed deeper
