Biogas from biodigester as energy source for Stirling engine prototype constructed from recyclable materials
Journal Title: IOSR Journals (IOSR Journal of Electrical and Electronics Engineering) - Year 2017, Vol 12, Issue 5
Abstract
Fish farm and fish industries production has been growing steadily, being great food sources and nutrition in Brazil and others countries. Its development also leads to an increase in the organic solid wastes generation such as fish viscera, which, due to incorrect destination, result in environmental problems and other adversities. Therefore, it is pertinent to verify the feasibility of using fish viscera as a carbon source for biogas production and as biofertilizer, through anaerobic digestion process by the construction of a biodigester prototype aiming to produce organic fertilizer and biogas. Such gas can be used as an energy source for Stirling engine, as this type of engine can use this fuel as heat source for conversion into mechanical energy, and this type of engine have been more efficient than diesel and gasoline engines. In this way, biogas obtained from a biodigester with fish viscera and bovine manure was used as heat supply fuel for Stirling engine prototype built for this research. From a quantitative analysis of the engine mechanical and thermal data, an average percentage efficiency of 19.99% and average speed of 328.31 rpm was obtained.
