Potential energy of the fuel briquettes from mangosteen shell

รายงานการวิจัย -- มหาวิทยาลัยเทคโนโลยีราชมงคลพระนคร, 2555The objective of this research is to use mangosteen shell that from household wastes for produce the fuel briquette. This fuel is used in terms of renewable energy which instead of firewood and charcoal from natural forest. We used the adhesive paste as a binder and briquette with hand pack filler. The results showed that the mangosteen shell can be burned to charcoal black and lightweight. By grinding mangosteen charcoal into small size, these charcoals were mixing with the paste. We have to compress the mixing charcoal molded into fuel briquettes. These briquettes are performed the stable and non-broken products. After sun drying, the results of potential energy testing showed that the calorific value 5920 cal/g, combustion rate 11.8 g/min, fixed carbon content 61.7%, and ash content 7%. For the combustion efficiency testing, our fuel briquette could be performed cooking as well, non-explosion, high combustible, non-soot, non-smoke and non-odors during used. These fuel briquettes are suitable for fuel products in household, community, or commercial production and industrial. Due to these advantages, our briquettes are possibly to instead of firewood and charcoal from natural forest which can be reduced the global warming by another way.Rajamangala University of Technology Phra Nakho
