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 kW_e 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.
