Use of vegetable oil as fuel to improve the efficiency of cooking stove

In this study, an attempt has been made to use waste vegetable oil as a fuel for a cooking stove. Suitable modifications have been made in the kerosene stove for use with vegetable oil as fuel. The efficiency of the stove using vegetable oil as fuel is observed to be as high as 48.9% as compared to 34.9% with that of a conventional stove when a flat copper bottom vessel is used. Corresponding efficiency increase is also observed with other vessels.
