Comprehensive evaluation of rice husks as a potential solid biofuel

Popis výsledku v původním jazyce

As the common crop residues in Vietnam, rice husks can potentially be a technically efficient, economically viable and environmentally sustainable bio-energy option, release a considerable heat for thermo-chemical conversion systems. The report provides a comprehensive evaluation in the nature, physico-chemical property, fuel characteristic, ash composition and transformation phenomena of this biofuel. Analysed results show sig-nificant calorific value (16-17 MJ/kg), high ash and volatile contents, low S, Cl contents in the test pieces. Low alkali cations were reported in the ash compositions while the obtained Si value was relatively high. Ash sof-tening and fusion processes were determined with heat generated continuously at constant rates (maintained at 550 ± 10 °C for 120 minutes, at 850 ± 10 °C for 240 minutes). First signs of deformation were recorded at temperature above 1450 °C, whereas volume expanding and bursting of internal gas bubbles were not pre-sented. Further elemental determination of ash compositions explains the decomposition of ash-forming ele-ments (Ca, Mg, Fe, Al, K, Na and P), by further oxidation (to higher oxidation states) and partial losses of volatile inorganic compounds.
