Abstract:Cilj diplomskega dela je opisati in predstaviti proces pirolize lesa in se osredotočiti na proces pirolize, kjer se pridobi največ trdnega produkta – to je proces torefikacije lesa. V prvem delu diplomskega dela je predstavljena lesna biomasa in pomen posameznih sestavnih delov v lesu. Predstavljen in opisan je postopek pirolize ter vsi tipi pirolize s prevladujočimi produkti in značilnostmi. Diplomsko delo je osredotočeno na počasno pirolizo, ki jo imenujemo torefikacija, ker pri tem postopku dobimo največ trdnega produkta. Drugi del diplomske naloge zajema podrobne opise različnih tehnologij, uporabljenih pri postopku torefikacije lesne biomase, kjer dobimo kot produkt toreficirane pelete. Narejena je energetska primerjava energentov – lesa, toreficirane biomase, toreficiranih peletov in oglja. Primerjava vključuje energetske vrednosti in gostote pri značilni vrednosti vlage v materialu. Za primerjavo je bil izbran kotel na trdna goriva za ogrevanje poslovnega objekta. Kotel obratuje po principu pirolize lesa. Preračunana je primerjava porabe posameznih energentov ter ekonomska in energetska analiza, v smislu kurilnih vrednosti vseh energentov. Energenti, ki so bili izbrani za izgorevanje v kotlu na trdna goriva, so les, lesni peleti, toreficirani peleti in oglje.

Title:PYROLYSIS OF WOOD BIOMASS
Abstract:The purpose of this diploma thesis is to describe and introduce the process of pyrolysis of wood and focus on the process of pyrolysis, which is the one that produces the largest quantity of solid products – this is the process of wood torrefaction. The first part of the thesis introduces wood biomass and the importance of individual wood components. The thesis presents the process of pyrolysis and all types of pyrolysis with their main products and characteristics. The thesis is focused on the slow pyrolysis, called torrefaction, because it is the process in which the largest number of solid products is produced. The second part of the thesis involves detailed descriptions of various technologies, used in the process of wood biomass torrefaction, the product of which is torrefied pellets. I have made an energy comparison of energy products – wood, torrefied biomass, torrefied pellets and charcoal. The comparison includes energy values and densities at different moisture value in the material. The solid fuels boiler used to heat business premises has been chosen for the comparison. The boiler operates on the wood pyrolysis principle. The thesis includes use calculations of individual energy products, economic and energy analyses, within the meaning of heating value of all energy products. The energy products chosen for combustion in the solid fuels boilers are wood, wood pellets, torrefied pellets and charcoal.
Keywords:Pyrolysis, biomass, wood, torrefaction, torrefied pellets, charcoal
