Potenciali in možnosti energetske oskrbe posestva Fakultete za kmetijstvo v Mariboru z lastno lesno biomaso : diplomsko delo - visokošolski strokovni študij

Fakulteta za kmetijstvo in biosistemske vede se ukvarja s kmetijsko in gozdarsko dejavnostjo. Njeno posestvo je teritorialno ločeno v dve enoti, prva enota se nahaja v okolici gradu Hompoš nad Hočami, druga enota pa na Meranovem nad Limbušem. Potenciali in možnosti lesa za kurjavo obstajajo na obeh lokacijah, tako iz gozdov, kot tudi iz kmetijske dejavnosti. Potencial lesa za kurjavo v gozdovih predstavlja les slabše kvalitete, ki nastane predvsem pri gojitvenih delih in pa sečni ostanki kot produkt redne sečnje. Potenciali s kmetijske dejavnosti so: les pri letni rezi vinogradov in sadovnjakov, pri krčitvah površin za obnove in les za kurjavo, ki nastane ob čiščenju melioracijskih jarkov. Trenutno rabo energentov na fakulteti v veliki meri predstavljajo kurilno olje, utekočinjen naftni plin in elektrika. Le del predstavlja les za kurjavo v obliki lesnih sekancev. Zato je smiselno poiskati druge možnosti. Le te so se pokazale v vgradnji kogeneracijskih sistemov, za soproizvodnjo toplotne in električne energije. Za zagotavljanje vseh potreb po energentih je potrebno vzpostaviti dva sistema, za vsako teritorialno ločeno enoto posebej. Kljub dokaj visokim investicijskim vložkom so se ekonomski izračuni izkazali kot ugodni. Z lastnimi potenciali lesa za kurjavo se lahko s soproizvodnjo zagotovijo vse energetske potrebe Fakultete za kmetijstvo in biosistemske vede.

• Title: Energy supply potentials and possibilities of the estate of the Faculty of Agriculture in Maribor with self-produced biomass

Abstract

The Faculty of Agriculture and Life Sciences is engaged in agricultural and forestry activities. Its' estate is separated into two units: the first unit is located in the vicinity of Hompoš castle above Hoče, the second one on Meranovo hill above Limbuš. Both locations have potentials and possibilities for fuel wood production using agriculture and forestry resources. The potential of fuel wood energy can be derived from lower quality wood primarily obtained from silviculture works, and forest residues generated from regular logging operations. It can also be derived from agricultural sources: pruning wood from vineyards and orchards, wood residues from grubbing before restoration, and those from cleaning melioration ditches. Currently, the main energy products used by the Faculty are heating oil, liquefied petroleum gas and electricity. Only a small portion of energy is generated from fuel wood, namely woodchips. It is therefore reasonable to look for other options. One of them is installing cogeneration systems, which provide both heat and electric power. In order to meet the energy needs, two separate systems have to be installed, one for each estate unit. Although this requires high investment costs, the results of financial evaluations are favorable. The energy supply from self-produced fuel wood is sufficient to meet all the energy needs of the Faculty of Agriculture and Life Sciences.
