Performance study of KHUNTIA stove: Comparison with Traditional stove Sl. Parameter Traditional stove KHUNTIA- Cook Stove 1. Construction Red Brick & clay Red brick, cement sand mortar & steel chimney 2. Cooking capacity 300 – 400 children 300 – 400 children 3. Firewood consumption 105 kg/day 75 kg/day 4. Fuel saving over traditional - 29% at present (Designed for 30%) 5. Cooking period 120 – 135 minutes 85 – 100 minutes 6. Smoke Excessive & burning eye Almost Nil 7. Room temperature Quite high (intolerable) Normal as outside 9. Tentative life 5 – 10 years More than 10 years 9. Cost About Rs . 2000/- About Rs.10,000/- 10. Recovery of cost Within two months 11. Fuel saving ----- IN Rs.50,000/- per year

Slide23:

Performance of Community stove after 24 months operation (January 2015) Both the stoves operated twice a day without halt during last two years. All benefits of the cook stoves; such as reduced fuel consumption, cooking time, gas free environment etc remain unchanged even after two year continuous operation. All benefits to users continues without changes. Chimney was not decarbonized ( cleaning of carbon shoot form chimney) during last two years. Combustion chamber & other parts are also not repaired. Top surface of one of the stoves was reinforced by a 10 mm thick mild steel plate, while other one has brick surface. Physical conditions mild steel clad stove found better than brick surface chulha . Tentative life of the stove is expected 10 years.
