Abstract
Šumska biomasa se sastoji od ostataka i otpada koji nastaju tijekom redovnog gospodarenja šumama. U biomasu iz drvne industrije spadaju ostaci piljenja, drobljenja itd. Može biti korištena kao gorivo u kotlovima ili kao sirovina za proizvodnju briketa, peleta i sl. Proizvodnjom peleta se ostvaruje dodana vrijednost iskorištavanja ostataka drva u pilani te industrijskih ostataka drva iz drvoprerađivačke industrije. Drvni pelet je obnovljivo gorivo s neutralnom emisijom ugljikovog dioksida. Jedna od bitnih stavki vezana za pelete je mehanička izdržljivost. Mehanička izdržljivost jedan je od najvažnijih parametara u proizvodnji peleta. Niska mehanička izdržljivost može prouzrokovati visok udio finih čestica što negativno utječe na kvalitetu peleta, ali i zadovoljstvo samog kupca. U ovom radu analizirat će se mehanička izdržljivost peleta hrvatskih proizvođača nakon izlaganja oštrim mikroklimatskim uvjetima. Oštri mikroklimatski uvjeti negativno će utjecati na svojstva peleta, a u ovom radu analizirat će se utjecaj povećane vlage na dimenzijsku stabilnost i mehaničku izdržljivost peleta. Mehanička izdržljivost mjerit će se pomoću dva uređaja: pelet-tester i ligno-tester.
Abstract (english)
Forest biomass consists of residues and waste generated during regular forest management. Biomass from the wood industry includes the remains of sawing, crushing, etc. It can be used as fuel in boilers or as raw material for the production of briquettes, pellets, etc. The production of pellets realizes the added value of utilizing wood residues in sawmills and industrial wood residues from the wood processing industry. Wood pellets are a renewable fuel with neutral carbon dioxide emissions. One of the important feature related to pellets is mechanical durability. Mechanical durability is one of the most important parameters in pellet production. Low mechanical durability can cause a high proportion of fine particles, which negatively affects the quality of the pellets, as well as the satisfaction of the customer. This work will analyze the mechanical durability of pellets produced by Croatian producers after exposure to harsh microclimatic conditions. Harsh microclimatic conditions will negatively affect the properties of pellets, and in this work impact of increased humidity on dimensional stability and mechanical durability of pellets will be analyzed. Mechanical durability will be measured using two devices: a pellet tester and a ligno tester.
