Abstract

U radu je prikazana karakterizacija drvne sječke kao čvrstog biogoriva koje se koristi za rad bioelektrana. Na uzorcima drvne sječke nakon odgovarajuće pripreme određivani su parametri: ukupna vlaga, sadržaj pepela, hlapivih tvari i klora, elementarna analiza (CHNS analiza), ogrjevna vrijednost, sadržaj elemenata u tragovima te temperatura tališta pepela. Sadržaj elemenata u tragovima određen je optičkom emisijskom spektrometrijom s pobudom u plazmi (ICP-OES) nakon razaranja uzoraka mikrovalnom digestijom uz HNO3. Rezultati ispitivanja pokazali su da kvaliteta drvne sječke odgovara zahtjevima norme: HRN EN ISO 17225-4:2014 Čvrsta biogoriva – Specifikacije goriva i razredi – 4. dio: Klasifikacija drvne sječke.

Abstract (english)

This thesis paper describes characterization of woodchips as biomass fuel for biomass-fired cogeneration plants. After preparation of woodchips samples determination of many parameters has been carried out: moisture, ash, volatile matter and chlorine, elementary composition (CHNS analysis), calorific value, trace elements contents and ash melting behaviour. Content of trace elements in woodchips samples was determined with inductively coupled plasma optical emission spectrometry (ICP-OES), after microwave digestion with HNO3. The obtained data show that the quality property of used wood chips complies with the requirements of the standard: HRN EN ISO 17225-4: 2014 Solid biofuels – Fuel specifications and grades - Part 4: Graded woodchips.
