Adaptation and Evaluation of Pellet Press Briquette Machine

Abstract

A good substitute for coal, lignite, and firewood is briquetted fuel made from agricultural leftovers. Compared to loose agro-residues, which have a specific density of 60 to 180 kg/m3 , briquettes have a high (1200–1450 kg/m3 ). Briquettes are formed right where they are made, thus reducing air pollution. In this work, a sawdust and coffee husk briquetting machine is redesigned and built. In this work, briquettes (solid fuels) were made using a screw-type briquetting to compress sawdust and coffee husk at different ratios. An effective densification technique that is suitable for small-scale applications is being adapted by screw press briquetting. The equipment has been modified to generate briquettes at a rate of 187.62 kg per hour. Briquette density, power consumption per kilogram of briquette produced, and calorific value per kilogram of briquette have all been examined in relation to the effect of moisture content in agro-residues and binders utilized. Paper was used as the binding agent, and different biomass binder ratios of 100:10, 100:12.5, and 100:15 were tested to assess the briquette's physical characteristics. The binder level has a big impact on the briquette's physical characteristics. level.
