In addition, the fuel does not burn at an optimal temperature, increasing particulate emissions (e.g. smoke) which can have a damaging effect on the health of families who often cook inside the home.
A ceramic inner lining captures heat created in the combustion chamber. This ensures that the energy is held in the stove, not lost into the surrounding air. The stove stays hot longer with less fuel.
The rocket stoves are designed to regulate the flow of air through the stove. This ensures that air passing into the combustion chamber is at a higher and more efficient temperature.
The long chamber draws smoke up through the flames, where the smoke combusts, reducing the amount of particulate emissions (smoke) released by the fire.
