Grassroot Innovations

To meet their daily cooking energy needs, large number of households in the country’s rural areas use traditional chulha/stoves, which consume firewood and other biomass as fuel. This stove has an additional/secondary combustion chamber for burning the un-burnt bio mass and hydrocarbons. As a result, the thermal efficiency of the stove has improved while the pollution has reduced. It can use coconut shell or wood as a fuel. 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.

Reduced Fuel Consumption: The secondary combustion chamber burns leftover fuel particles, requiring less firewood or coconut shell to achieve the same cooking heat. This saves money and resources.
Improved Efficiency: Higher combustion efficiency (37.67% for wood, 29.48% for coconut shell) translates to less wasted heat energy and faster cooking times.
Lower Emissions: By burning fuel more completely, the stove reduces smoke and harmful pollutants released into the environment, improving air quality.
Fuel Versatility: The ability to use both wood and coconut shell as fuel provides flexibility based on availability and affordability.
