Biobriquette Characteristics of Mixture of Coal-Biomass Solid Waste Agro

Abstract

Bio-briquettes are solid fuel made from a mixture of coal with biomassai, solid fuel is an alternative fuel replacement for kerosene and gas are the cheapest. Biomass (coconut shells, sawdust and bark durian) chemically has a high carbon content and flammability. Biobriket made from a mixture of coal - biomass using taro flour as an adhesive and a solution of 50% alcohol as an additive can be used as an alternative fuel economic value. Based on the analysis Proximate and Ultimate, this research data obtained karakterik bio-briquettes with three variations of a mixture of a mixture of coal-coconut shell charcoal, coal-charcoal sawdust and coal-charcoal leather durian, of the three variations campurana which gives the best results is a mixture of coal-coconut shell charcoal at a ratio of 1: 4 with characteristics, Ash = 2,51%, Moisture = 4.83%, Volatile matter = 28.81%, Sulfur = 0.5445%, and calorific value = 6494 kcal / kg, maing gas emissions in all SO2 = 103 ppm NOx = 3 ppm.
