Abstract

Nove smjernice EU obuhvaćaju održivu poljoprivrednu biomasu kao sirovinu za proizvodnju energije. Poljoprivredni i agroindustrijski ostaci imaju dobar potencijal za proizvodnju energije neposrednim izgaranjem. Cilj rada bio je utvrditi energetsku iskoristivost kora ranih sorti mandarina koje ostaju nakon prerade te utvrditi njihov energetski potencijal u svrhu dobivanja energije. Analize su provedene radi utvrđivanja energetske iskoristivosti, a istraživani parametri bili su: sadržaj vode, pepela, koksa određivanje gornje i donje ogrjevne vrijednosti, mikro i makroelementi. Najbolje rezultate imala je sorta Saigon. Nakon provedenih analiza dobivene su prosječne vrijednosti za sadržaj vode 13,52%, za pepeo 2,83%, za koks 11,2%, gornja ogrjevna vrijednost iznosila je 16,2%, a donja ogrjevna vrijednost iznosila je 14,88%. Sukladno dobivenim rezultatima analiza, može se zaključiti da kora nudi mogućnost iskorištenja u energetske svrhe.

Abstract (english)

New EU guidelines include sustainable biomass as a raw material for energy production. Agricultural and agroindustical residues have good potential for utilization in energy production. The aim of this study was to investigate the efficiency of peel mandarin in energy production through process indirectly combustion. The best results had the Saigon variety. After the analyzes carried out, average values for water content were 13.52%, ash 2.83%, coke 11.2%, top calorific value was 16.2%, and lower calorific value was 14.88%. According to the results of the analysis, it can be concluded that the mandarin peel offers the possibility of utilization for energy purposes.
