Design criteria are important for improving stove performance, and design solutions exist for creating stoves that succeed in improving all six performance criteria. Two design criteria must be met to create a stove that uses less fuel and produces less pollution: improving fuel combustion (combustion efficiency) and directing more of the heat into the pot (heat transfer efficiency). High combustion temperatures and good mixing of gases, air and fire reduce dangerous emissions through more complete combustion. Forcing the heat to scrape against the pot in small channels dramatically increases heat transfer efficiency, thereby reducing the fuel used for cooking. The presentation explains in detail the various factors that affect combustion and heat transfer. | WORLD HEALTH ORGANIZATION MONOGRAPH SERIES No. 46 AIR POLLUTION AIR POLLUTION CONTRIBUTORS K.
