Tehnološke značilnosti izdelave lesnih kuriv : diplomsko delo - visokošolski strokovni študij = Technological characteristics of wood fuel production : graduation thesis - higher professional studiesKaker, DejanNastajajoča energetska kriza odpira možnosti alternativnim energetskim virom, istočasno pa pridobivajo na pomenu klasična lesna kuriva, oplemenitena z novimi tehnologijami izdelave. S stiskanjem ... lesne mase lahko zagotovimo višje kurilne vrednosti kuriv, lažji transport in skladiščenje. Postopki izdelave stiskancev so odvisni od končnega proizvoda v obliki sekancev, peletov ali briketov. Na energijsko učinkovitost vplivajo predvsem kakovost lesne mase in njena vlažnost, na uporabnost stiskancev pa tudi pogoji med izdelavo. Vplive vlažnosti in temperature med stiskanjem smo raziskali z laboratorijskimi poskusi. Izdelana je bila posebna stiskalna naprava za izdelavo stiskancev, ki smo jo vstavili v testirni stroj Zwick. Bukovo žagovino smo uravnovesili na vlažnosti 9,8 %, 11,8 %, 14,8 %, 18 % in 27,4 %. Stiskance smo izdelovali pri temperaturah 50°C, 60 °C, 70°C in 80 °C. Po fazi stiskanja, ki je trajala okoli 72 s, smo opazovali sproščanje notranjih napetosti v stiskancih oziroma relaksacijo stiskancev. Rezultate meritev smo normalizirali s pomočjo modelov za stiskanje in sproščanje. Poskusi so pokazali, da smo dobili največje kompaktnosti stiskancev pri vlažnostih pod 15 % in temperaturah nad 50 °C.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [D.
