Abstract

U ovom diplomskom radu analiziralo se dodavanje poljoprivrednih sirovina, konkretno kukuruza i suncokreta, osnovnoj sirovini hrasta, na način i u omjerima da se zadrži ENplus kvaliteta peleta prema HRN EN ISO 17225. Redom su se ispitivali sadržaj vode, udio pepela, kalorijska vrijednost, vodoupojnost, dimenzijska stabilnost i tlačna čvrstoća. Dobiveni rezultati opravdali su očekivanja i ciljeve rada, te se miješanjem poljoprivredne biomase s drvnom mogu proizvesti peleti koji će svojim gorivim svojstvima, ali i mehaničkom čvrstoćom zadovoljavati sve normirane kriterije.

Abstract (english)

In this thesis, it was analysed the addition of agricultural raw materials, specifically corn and sunflower to the basic raw material of oak, in a way and in proportions to maintain the ENplus pellet quality according to HRN EN ISO 17225. Moisture content, ash content, calorific value, water absorption, dimensional stability and compressive strength were examined. The final results justified the expectations and goals of the thesis, and by mixing agricultural biomass with wood, pellets can be obtained that will satisfy all standardized criteria with their fuel properties and mechanical strength.
