Energijska učinkovitost sušilnega postopka v različnih tehnologijah predelave žaganega lesa : diplomsko delo - visokošolski strokovni študij = Energy efficiency of drying with different sawmill technologies : graduation thesis - higher professional studiesObronek, FrancPri 3 načinih predelave (A - tehnično sušenje svežega žaganega lesa do ciljne vlažnosti 8 %; B - sušenje svežega žaganega lesa na prostem do območja nasičenja vlaken in tehnično dosuševanje elementov ... do ciljne vlažnosti; C - razžagovanje svežega žaganega lesa v elemente in tehnično sušenje elementov dokončne vlažnosti) in nadaljnjim sušenjem žaganega lesa smo primerjali čase sušenja, vso porabo energije, specifično porabo energije, toplotno učinkovitost in energijsko vrednost lesnih ostankov. Izračune smo izvedli z računalniškim programom, ki je omogočal variiranje vhodnih parametrov in proučevanje njihovega vpliva na analizirane vrednosti. Najvišjo toplotno učinkovitost, najkrajše čase sušenja in najmanjšo kapaciteto sušilnih komor dosežemo pri razžagvanju svežega žaganega lesa v elemente (C), vendar pa je tveganje večje, kalorična vrednost ostankov pa nižja. Energijsko najpotratnejše je sušenje žaganega lesa (A), zahteva pa tudi največje kapacitete sušilnih komor. Z izvajanjem predsušenja na prostem podaljšamo čas sušenja, bistveno pa se zmanjša vsa poraba energije in potrebne kapacitete komor. S pravilno izbiro tehnologije predelave lesa in sušenja pridobimo oziroma prihranimo energijo (razmerje med porabljeno in pridobljeno energijo je 1 : 7,12).Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [F.
