Combustion and Emission Characteristics of Water Hyacinth Based Composite Briquettes

Okia D.O., Ahmed M.S., Ndiema C.K.

Abstract: Biomass has been used in the last few decades as energy source to mitigate greenhouse gas emission during production and utilization. However, majority of biomass are bulky, uneven and have low energy density and therefore not suitable to be utilized as fuel without an appropriate process. The study was conducted to evaluate combustion and emission characteristics of composite water hyacinth briquette as an alternative source of energy. Water hyacinth was chopped using a shredder and left for two weeks in a heap to partially decompose. The material was thoroughly mixed manually with dried and crushed charcoal dust and cow dung in the ratios as done by Okia et al of water hyacinth,2016: charcoal dust: cow dung of 100:0:0 (control), 80:10:10, 70:20:10, 70:10:20, 60:30:10, 60:20:20 and 60:10:30 (by weight). The resulting material was then mixed into soupy slurry in water. Simple prototype briquetting mold was fabricated to facilitate densification of these residues into hollow cylindrical briquette at a pressure of 1MPa. The experimental results revealed that the mixture that gives optimal combustion characteristics was 60:30:10. Water hyacinth alone (100:00:00) gave the best emission characteristics having 28.51ppm carbon monoxide and 452.80ppm carbon dioxide though ranking third with 13,623 µg/m3 in particulate matter. This study demonstrates that composite water hyacinth briquettes have good combustion and emission characteristics therefore can be utilized as alternative source of energy.
