Among the available alternative sources of energy in Bangladesh bio-oil is recognized to be a promising alternative energy source.\r\nBio-oil can be extracted by pyrolysis as well as expelling or solvent extraction method. In these days bio-oil is merely used in vehicles\r\nand power plants after some up gradation .However, it is not used for domestic purposes like cooking and lighting due to its high\r\ndensity and viscosity. This paper outlines the design of a gravity stove to use high dense and viscous bio-oil for cooking purpose.\r\nFor this, Pongamia pinnata (karanj) oil extracted by solvent extraction method is used as fuel fed under gravity force. Efficiency of\r\ngravity stove with high dense and viscous bio-oil (karanj) is 11.81% which of kerosene stove is 17.80% also the discharge of karanj\r\noil through gravity stove is sufficient for continuous burning. Thus, bio-oil can be effective replacement of kerosene for domestic\r\npurposes.
