Resumo

Biodiesel is a renewable energy resource, which has the potential to reduce greenhouse emissions and to facilitate energy sustainability. It can provide an alternative to petroleum-based diesel. The combustion characteristics of diesel and biodiesel such as burning rate and flame shape are determined by using the porous-sphere experimental technique. Fuel has been transpired to the surface of a porous sphere. Burning of the fuel takes place on the surface of the porous sphere, which is placed in atmospheric pressure and temperature under normal gravity conditions. For each sphere size and fuel type, the fuel feed rate will vary and the same is recorded as the burning rate for that configuration. The burning rate is determined experimentally and compared for diesel and biodiesel of Pongamia Pinnata (Karanja). The flame shape is analyzed by post-processing the digital image of the flame photograph using suitable imaging software. Results show that the diesel fuel has higher burning rate and evaporation rate when compared to biodiesel. The height of the diesel flame, smoke emission and its luminosity is higher than that of biodiesel.Keywords: Porous sphere; Karanja oil methyl ester; Biodiesel; Flame structure
