Abstract
Brazil is a country whose agricultural and agroindustrial activity has grown considerably. In fish processing, there is the availability of residual fat, which when transesterificated originates fish biodiesel, which can replace diesel oil as a fuel in diesel engines. In this study, the aim was to evaluate the performance of an engine generator set (by Branco), with a power of 7.36 kW (10 hp) coupled to a generator of 5.0 kWe using 100% fish biodiesel (B100) and 20% pure biodiesel (B20) in comparison to the pure diesel (B0). Assays were performed by varying the load of the generator. Results show that, the performance of the engine generator set using B100 is higher than that with B0, for a maximum test load of 2.6 kW. An overall efficiency of the engine generator set of 21.6% was found for the load of 2.6 kW. Key words: Energy, biofuel, electricity, biomass.
Highlights
The Brazilian territory has a huge extension and its climate is conducive to agro industrial activities because it is a country with great potential for exploration of the biomass for food, chemical and energy purposes, and to produce biodiesel (Feltes et al, 2010).Brazil has fishing potential as few countries in the world due to the amount of marine and continental waters
Biodiesel is a renewable biofuel and can be used in four-stroke diesel cycle engines without major complications, replacing mineral diesel, being the biodiesel conducted as the primary fuel fish biodiesel (B100) or added to diesel oil (Neto et al, 2000)
The use of residual fat from fish processing helps to meet the need for new raw materials for biofuel production, and solves the environmental problem entailed by the waste generated from the processing of fish, bringing economic and sustainable benefits for fish farming (Kulkarniv and Dalai, 2006)
Summary
The Brazilian territory has a huge extension and its climate is conducive to agro industrial activities because it is a country with great potential for exploration of the biomass for food, chemical and energy purposes, and to produce biodiesel (Feltes et al, 2010). The use of fish fat to make biodiesel is an alternative to the energy matrix, as well as other raw materials such as vegetable oils, animal fats, and others (Martins, 2012). The production of biodiesel based on residual fat from the fish processing farms is an alternative to the production by means of vegetable oils and contributes to decrease the use of arable lands for the production of oilseeds for energy purposes, allowing such areas to be used for the cultivation of food. The use of residual fat from fish processing helps to meet the need for new raw materials for biofuel production, and solves the environmental problem entailed by the waste generated from the processing of fish, bringing economic and sustainable benefits for fish farming (Kulkarniv and Dalai, 2006). Of 7.36 kW (10 hp) and 5.0 kWe generator running on B100, pure diesel (B0), and pure biodiesel (B20), 20% biodiesel mixed to mineral diesel
