Vpliv temperature v kopi na kakovost oglja [Elektronski vir] : diplomsko delo - visokošolski strokovni študij - 1. stopnja = Influence of temperature on the quality of charcoal from charcoal pits : B. Sc. Thesis - Professional Study Programmes
Frece, Domen
V nalogi smo preučevali vpliv temperature med oglenitvijo v oglarskih kopah na kakovost oglja iz teh kop. Temperature smo merili z 2 posebnima temperaturnima sondama v 5 kopah različnih velikosti. ...Temperature so bile izmerjene v vsaki kopi v strženu in na obodu. Po končani oglenitvi smo iz mest merjenja odvzeli tudi vzorce oglja, katere smo nato analizirali na Gozdarskem inštitutu Slovenije in s tem ugotovili kakovost oglja. Rezultati so pokazali, da se višje temperature v povprečju razvijejo v strženu kope. Prav tako je bila višja temperatura med oglenitvijo dosežena pri uporabi svežega lesa in izdelava kop večjih velikosti. Kakovost oglja je bila pri vseh vzorcih oglja dobra. Izkazalo pa se je, da je najbolj problematičen kazalnik kakovosti oglja granulacija, saj je premalo najbolj pomembne srednje frakcije (20-80 mm), preveč pa velikih frakcij (nad 80 mm). Analiza rezultatov je nakazala vpliv temperature na kakovost oglja. Pri višjih temperaturah je nastajalo oglje boljše kakovosti. Dokazali smo, da pri povprečnih temperaturah nad 400°C nastaja kakovostnejše oglje kot pri temperaturi okoli 200°C.
