About the Practice
Problem Statement:

High use of fuel, a lot of smoke from the conventional chulhas


Jayprakash’s innovative stove is a double chambered efficient portable stove, used primarily for community cooking. It can use coconut shell or wood as a fuel. This portable stove is made of bricks, cement, clay, cast iron and can cook food upto 100 kg. The base of the bottom chamber is made of iron grill on which the fuel is kept. Below the grill is an air chamber. When the fuel burns, smoke mixed with unburnt hydrocarbons reaches the upper chamber, which has been provided with air inlet holes. Complete combustion takes place here and the combined heat gets available to the cooking vessel above the second chamber. The fuel opening has been provided at the front of the device and can be regulated using shutter, which in turn controls the flow of air. The air which flows through the opening during combustion causes an updraft when the fuel is burnt. This triggers secondary combustion as the carbon particles, which were left unburned will now get burned due to the additional air. Apart from its efficiency, lower cost and portability are also significant features of this stove. The combustion efficiency is in the range of 37.67% when wood is used as a fuel and 29.48% when coconut shell is used.
