SOLID RECOVERED FUELS FROM AGRICULTURAL WASTES

ABSTRACT: Solid recovered fuels are fuels produced directly or indirectly from the biomass. Main goal of this work is to analyze some selected solid recovered fuels from agricultural wastes which were in form of briquettes. They were analyzed in order to find out chemical and stoichiometric composition and energy balance. Technical standard ČSN EN 13229 “Inset appliances for heating including open fires fired by solid fuels – Requirements and test methods ” was performed to determine the basic assessment of thermal efficiency and emission parameters. A prototype of combustion accumulation stove SK-2 (nominal heat output of 8 kW) was used. Tested materials were the bio-briquettes with a diameter 65 mm from mixture of fermented mixture 33 % (rotten fermented waste treatment slurry) and 67 % wood ships, cereals cleaning residues, mixture of cereals cleaning residues and meadow grass in a ratio 1:1 and mixture of cereals cleaning residues and energy sorrel in a ratio 1:1. Key Words: Solid alternative- recovered fuels, bio-fuel, stoichiometric calculations, emissions and energy parameter
