The Efficiency Comparison of Fuel Briquettes from Agricultural Wastes
Keywords:Fuel briquette; Agricultural waste; Cassava starch sediment
The objectives of this research were to study the feasibility of fuel briquettes from various types of agricultural wastes, to study the optimal ratios of agricultural wastes and binder and to compare the efficiency of chemical and physical properties on fuel briquettes from agricultural wastes. The experiment was conducted by the agricultural wastes such as bagasse (BG), rubber wood sawdust (WS), corn cobs (CC), rice straw (RS), leaves of para rubber (LP) and rubber wood chips (RC) that were mixed with dry cassava starch sediment (CS) as a binder at the ratios of 0.25:0.75, 0.50:0.50 and 0.75:0.25 kg:kg, respectively. Also, the fuel briquettes were formed by a cold pressed process. Then, study of chemical properties of fuel briquettes were heating value, moisture content, and ash content and their physical properties were density and drop shatter test including performance of fuel briquettes from agricultural wastes. Results showed that the fuel briquette from rubber wood chips mixed with cassava starch sediment was at 0.50:0.50 was the most effective alternative fuel (heating value was 4,136.9728 cal/g, moisture content and ash content was 7.33 and 5.33 % w/w respectively, density of 0.47 g/cm3 and drop shatter of 0.78) and it can be applied as a guideline of fuel briquettes from agricultural wastes for using alternative energy source in community.
