In Ethiopia, the disposal of weeded water hyacinth from Lake Tana is a significant problem, but it can be solved by transforming it into a useful energy source using briquetting technique. This study deals with the adaptive design and development of appropriate screw press type water hyacinth (WH) briquetting machine and combustion property characterization of the developed WH briquette. By combining the three functions of crushing, mixing, and briquetting into a single machine rather than using separate devices, the developed screw-press briquetting machine saves on space, labor, and material handling, as well as lowering costs and speeding up production. Hopper, mixer, extruder, and die were used in the development of this briquette machine. The machine was designed to employ WH from Lake Tana and cow dung at a weight ratio of 80:20. The performance of the developed screw press briquette machine was evaluated and the results showed that the WH briquette machine has an average production rate and efficiency of 40 kg/h and 95%, respectively. The quality of WH briquette was evaluated using the compressed density, ash content, volatile matter, fixed carbon content, and calorific values (CV) parameters. The results showed that the density of 0.75 g / cm 3 , ash content of 22.7%, volatile matter of 49.5%, fixed carbon content of 15.3%, and CV of 19.23 MJ/kg were attained. Therefore, the produced WH briquette could be used as a sustainable energy source for household applications. [ABSTRACT FROM AUTHOR] |
