Abstract

Lesni sekanci se v Sloveniji najpogosteje uporabljajo kot kurivo za proizvodnjo toplote v večjih toplarnah. Za investicije povezane s postavitvijo individualnih sistemov za proizvodnjo toplote, se ljudje običajno ne odločajo. Za investicijo so potrebna relativno velika finančna sredstva, ki pa jih v trenutnih tržnih razmerah ni enostavno pridobiti, oziroma so zelo draga. Analizirali smo različne sisteme za proizvodnjo sekancev, predvsem z vidika kapacitet in porabe energije. Porabo električne energije v procesu proizvodnje lesnih sekancev smo spremljali na sekalniku Lindner T650/250. Uporabili smo les dveh, v naših gozdovih najpogostejših drevesnih vrst, to je smrekovine (Picea abies L.) in bukovine (Fagus sylvatica L.). Ugotovili smo, da je za izdelavo sekancev iz bukovih golic porabimo za 50 % več električne energije kot pa za izdelavo sekancev iz celuloznega lesa smrekovine. Ugotovili smo tudi, da na porabo energije v veliki meri vpliva tudi velikost sekancev.

Secondary title:	Consumption of energy at wood chips production
Secondary abstract:	In Slovenia, wood chips are used in most common way for heat production in heating stations; investments to build individual heat stations are too expensive. We analysed different systems for wood chips production, mainly as regard capacity and electricity consumption. To produce wood chips Lindner T650/250 chipper and 2 different wood species, the spruce tree (Picea abies L.) and the beech tree (Fagus sylvatica L.) were selected. The consumption of energy used for this process was analysed. The beech wood consumed 50 % more of electrical energy than spruce wood. The consumption was also related to the dimensions of wood chips.
