Vpliv temperature sušenja na vezivne lastnosti lesnih peletov : diplomsko delo - visokošolski strokovni študij = Influence of drying temperature on adhesive properties of wood pellets : graduation thesis - higher professional studiesFerjan, DavidV proizvodnji lesnih peletov se kot vhodna surovina pogosto uporablja vlažna žagovina. Za izdelavo peletov je žagovino potrebno osušiti, za kar se pogosto uporabljajo sušilniki s sušilnim bobnom, v ... katerem se žagovina suši s pomočjo dimnih plinov. Pri temperaturi sušenja žagovine nad 250 °C se pri peletiranju pojavijo težave. Predvidevamo, da visoke temperature sušenja vplivajo na vezivne lastnosti surovine, predvsem na količino lignina, ki v peletih deluje kot vezivo. V nalogi smo ugotavljali vsebnost lignina v žagovini, ki smo jo sušili z dimnimi plini pri temperaturah 200 °C, 230 °C, 375 °C, 400 °C, 420 °C in 440 °C. Spremembo količine lignina v žagovini smo preverjali po dveh metodah, z delignifikacijo in z določanjem vsebnosti lignina po Klasonu. Opravljene analize žagovine za izdelavo peletov niso pokazale odvisnosti vsebnosti lignina od povišane temperature sušenja surovine z dimnimi plini. Ugotavljamo, da so potrebne dodatne analize, ki bi dale odgovor na to, katera komponenta in v kolikšni meri se spremeni ob povišani temperaturi sušenja, da se to rezultira v obliki slabše vezivnosti surovine za izdelavo peletov.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [D.
