Physical and chemical properties of fuel pellets from agricultural residues
2016
Acda, M.N.
The study investigated the physical and chemical properties of fuel pellets from agricultural residues viz., rice (Oryza sativa L.) straw, rice hull, corn (Zea mays L.) cobs, sugarcane (Saccharum officinarum L.) bagasse, waste tea (Camella sinensis L.) leaves, tobacco (Nicotiana tabacum L.) stalks, dalandan (Citrus aurantium L.) peel, banana (Musa acuminata) peduncles and pili (Canarium ovatum Engl.) nuts. Proximate, ultimate and elemental analyses were performed to assess fuel properties of pellets from biomass residues. In general, moisture content, particle and bulk density, mechanical durability, calorofic values and potential level of pollutant emission were within recommended limits of compressed solid fuel for industrial thermal processes. However, high levels of ash and deposit-forming elements were detected from fuel pellets produced using agricultural residues used in this study. These limitations may pose a major challenge for the use of agricultural residues as fuel pellets in the Philippines.
