This project involves replacing traditional wood stoves in homes with more efficient cooking technology. Firewood saving cookstoves are a rural energy technology that has been used for more than 30 years in China. They have an additional chimney and proper air supply system, which enables fuel to fully burn and extracts the waste gas out of the room. At the same time, the special inner smoke route in the stove body makes good use of the energy of the hot smoke. The improved stove can thus save as much as 50-60% of the firewood needed for daily cooking.
