Abstract

Most of the developing countries are generating large amounts of agricultural waste but they are used ineffectively causing to pollute the environment. The main agro-wastes are rice straw, cotton stalks, and maize straw in addition to this biomass milling residue is also available in huge quantity. Apart from the problems of storage, handling, transportation, direct burning of loose biomass in conventional grates is associated with very low thermal efficiency and widespread air pollution. To overcome these problems, biomass needs to be compressed ten times to increase its density and durability. In this study, durability, density and compression strength of sawdust, cotton stalks, maize straw and rice straw briquettes at different levels of moisture content, particle size and compression ratio is to be determined. It is found that the maximum durability, density and compression strength of sawdust (94%, 1005 kgm−3, 9.8 MPa), cotton stalks (91%, 1001 kgm−3, 9.5 MPa), maize straw (85%, 998 kgm−3, 8.2 MPa) and rice straw (78%, 975 kgm−3, 7.7 MPa) respectively was at 12% moisture content, 1:10 compression ratio and 3 mm particle size. The effect of compression ratio was Maximum as compared to moisture content and particle size. It was also found that durability and compression strength of rice straw briquettes was minimum as compared to sawdust, cotton stalk and maize straw briquettes.Keywords: Biomass, density, durability, compression strength, moisture content, particle size, compression ratioCite this Article: Ali Muhammad Azhar, Nasir Abdul, Muneer Anjum, et al.
