Conservation of biofuels is an urgent need of the present hour for reducing pressure on the
natural forest resources and meeting the alternative requirements. In the present investigation a traditional biomass stove, presently used by 120 million households in India, and the Sugam-II stove, developed and
dessiminated by TBU, liT Delhi, were used for observing fuel utilization efficiency. Acacia nilotica wood, dung cake and agro-waste (mustard twigs) were used at a feeding rate of 16.70-33.30g/min and 12.50-33.30 g/min for the two stoves, respectively. The water boiling and evaporation test was used for the performance determination of both stoves. The maximum thermal efficiency of the traditional and Sugam-lI stoves was achieved at a feeding rate of 25 and 16.67 g/min, respectively. Fuel wood for both
stoves provided the highest thermal efficiency. The test conducted on the modified stoves showed that if the chimney of the Sugam-II was removed, it gave the best performance when a I cm raiser was provided in the second pot hole and one-third of the raiser opening was closed.
