Sampada ELFD Smokeless Stove

The Sampada stove is a natural draft gasifier which produces charcoal as a bye product. For every kg of wood burned, it is possible to get cooking energy for about 30 min with about 200 gm of charcoal left behind. The charcoal can be used as fuel in a charcoal burning stove or can also be used as biochar for addition to the soil for carbon sequestration and soil fertility improvement. This stove is designed for community cooking.

The Sampada stove is sold primarily through direct sale to customers in exhibitions and weekly markets. Appropriate Rural Technology Initiative (ARTI) has 300 units sold so far, but over the years, the stove has undergone design improvements based on user feedback. No data is available on how many stoves are in use. ARTI conducts its own thermal efficiency testing.
