An improved wood burning metallic cook stove is presently designed and fabricated. During test, measured thermal efficiency is found 24%. Smoke emission is also reduced. Wood sticks, twig etc. can be used as fuel in this stove. Power output rating of the present prototype is 2.88Kw per hour. Cost of the stove is within economical limit.
Area of Application: For the use in rural area both for domestic and community cooking purpose. The presently fabricated prototype is designed to cook meals for 50 persons at a time.
Keywords: High thermal efficiency, less emission.
Advantages: 1.High thermal efficiency with reduced smoke emission. 2.In the stove, primary air is supplied throughout the perforated circumferential wall at the lower part of combustion chamber for better mixing with wood fuel during combustion. 3.Double walled secondary air passages reduce heat loss to the surroundings. 4. The primary air is entered through perforated wall located above the fuel rest plate, not through conventional grate at bottom so that, deposited ash on fuel rest plate cannot be able to block the air passage for primary air entry. 5.Ash removal is very easy, just by opening of holding clip of fuel rest plate.
