Traditional Cooking Devices
Literature reports that the three stones open fire (TSF) persists as the most prevalent fuel-using technology to cook the meals in the villages and urban slums of the developing world. Traditional stoves have been around for thousands of years and have evolved to meet the local needs in a way that is affordable for the users. There are many sophisticated types of traditional stoves, ranging from mud stoves to heavy brick stoves to metal ones
Fuel Use in Traditional StovesIn rural households, food is generally cooked on clay stoves. These stoves use biomass as fuel. A family of 5 to 6 persons requires about 8kg of fuel every day. Surveys showed that, on an average, the domestic fuel consists mainly of agricultural residues and cattle dung, supplemented by wood to the extent of about 40%. The former is generated in the family farm, while the latter, consisting mainly of branches of trees, is collected in the neighbourhood. Even families who can afford modern fuels, prefer to use biomass because it is available free of cost. In forested regions, the fuel consists almost exclusively of wood.

Housewives and infants are affected the most by these pollutants, because they are maximally exposed to the flue gases.
