Kurilnost razkrojenega lesa

Živa Krelj (Author), Miha Humar (Author)

Abstract

Wood is one of the most important sources of energy. The industrial energy plants mostly use wood in the form of chips or pellets. Chips are often stored outdoors. They are exposed to the fungal decay in such conditions. However, there are no data on the caloric value of decayed wood. Experimental data showed that the brown rot fungus Gloeophyllum trabeum did not affect the calorific value of spruce wood.On the other hand, white rot fungus Trametes versicolor, decreased the calorific value of decayed beechwood by approximately 2,5%.

Secondary abstract:	Les je eden izmed najpomembnejših energentov. V industrijskih energetskih napravah uporabljamo les v obliki sekancev, briketov ali peletov. Sekanci so pogosto skladiščeni na prostem, kjer relativno hitro pride tudi do glivnega razkroja. Pri tem se postavlja vprašanje, kakšna je kurilnost razkrojenega lesa v odvisnosti od časa izpostavljenosti. Eksperimentalni podatki kažejo, da gliva rjave trohnobe Gloeophyllum trabeum ni vplivala na kurilnost smrekovine, gliva bele trohnobe Trametes versicolor pa je v 10-ih tednih zmanjšala kurilnost bukovine za približno 2,5 %.
