20.500.12556/DiRROS-22547 Vpliv mesta shranjevanja na lastnosti lesnega oglja in briketov lesnega oglja za žar The effect of storage place on the characterisics of wood charcoal and wood charcoal briquettes for grilling V raziskavi smo proučevali vpliv zračne vlage na kakovost in kurilno vrednost lesnega oglja ter briketov lesnega oglja za žar. Uporabili smo slovensko lesno oglje s kmetije Frece in brikete lesnega oglja znamke Forest Premium. Lesno oglje in brikete lesnega oglja smo razdelili v štiri vzorce, ki smo jih hranili na štirih različnih lokacijah: v drvarnici, zunaj pod balkonom bivalnega objekta, v izolirani neogrevani garaži in v kurilnici. Vzorce smo vsak dan tehtali, poleg tega smo na lokacijah shranjevanja merili temperaturo in zračno vlago. Po 14-dnevnem obdobju meritev smo vzorce vneli, da smo pridobili podatke o temperaturi zgorevanja in času gorenja, del vzorca pa smo porabili za analizo vsebnosti vode in kurilne vrednosti. Najvišjo vsebnost vode sta imela vzorca lesnega oglja in briketov lesnega oglja, ki sta bila izpostavljena najvišji zračni vlagi, najnižjo vsebnost vode pa vzorca, ki sta bila izpostavljena najnižji zračni vlagi. Vzorci z višjo vsebnostjo vode so imeli tudi manjšo kurilno vrednost in temperaturo zgorevanja. Briketi lesnega oglja so izkazali večjo higroskopsko sposobnost, ki je verjetno vplivala na sposobnost za vžig (vzorci izpostavljeni višji zračni vlagi se niso vneli). Lesno oglje je kljub enakim razmeram shranjevanja ohranjalo večjo kurilno vrednost v primerjavi z briketi lesnega oglja. Rezultati raziskave poudarjajo pomembnost pravilnega shranjevanja lesnega oglja in briketov lesnega oglja, kakršno je suho in toplo okolje. Tako dosežemo optimalno energetsko učinkovitost in trajnostno rabo teh energetskih virov. In this study, we primarily examined the impact of air humidity on the quality and calorific value of wood charcoal and briquettes for grilling. We used Slovenian wood charcoal from Kmetija Frece and Forest Premium brand wood charcoal briquettes. Wood charcoal and wood charcoal briquettes were divided into four separate samples, which were stored at four different locations: in a woodshed, outside under the balcony of a residential building, in an unheated, insulated garage, and in a boiler room. The samples were monitored daily by weighing. Temperature and air humidity were also automatically measured at the storage locations. After a 14-day measurement period, the samples were ignited to obtain data on ignition temperature and burning time. A portion of the sample was also used to analyse water content and calorific value. The highest water content was found in samples of wood charcoal and wood charcoal briquettes exposed to the highest air humidity, while the lowest water content was found in samples exposed to the lowest air humidity. Samples with higher water content also had lower calorific value and ignition temperature. Wood charcoal briquettes exhibited a higher hygroscopic capacity, which likely affected their ignition ability (samples exposed to higher air humidity did not ignite). Despite the same storage conditions, wood charcoal maintained a higher calorific value compared to wood charcoal briquettes. The results of this study emphasise the importance of proper storage of wood charcoal and wood charcoal briquettes in dry and warm environments, as this ensures optimal energy efficiency and sustainable use of these energy sources. trda goriva za žar lesno oglje briketi lesnega oglja kakovost shranjevanje solid fuels for grilling wood charcoal wood charcoal briquettes quality storage true false true Slovenski jezik Angleški jezik Neznano 2025-06-03 12:22:41 2025-06-03 12:22:41 2025-10-24 03:51:31 0000-00-00 00:00:00 2025 0 0 str. 20-30 št. 1/2 Letn. 83 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2025-01-01 630*86 0017-2723 238095363 GV_1_2025_web2-22-32.pdf GV_1_2025_web2-22-32.pdf 1 365914FEBCCA3C7FEAA549F42D65202B b6a301debd0fd9ea033f20d6ab2c909328900ece66249981379ade6d02a6a2f7 460507c9-4a7d-11f0-bf0a-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=32840 Zveza gozdarskih društev Slovenije Gozdarski vestnik 0 0 0
