3.2. Emission from stove
Emission of pollutants from biomass fuel during combustion depends on the quantities of fuel consumed and type of combustor used. Domestic cooking is a major source of emission from biomass. However, with increase in the efficiency of stove, the amount of CO2 and CO emission inside the kitchen has been reduced, which was measured at a distance of 1 m from wood gas stoves with the help of gas analyzers (AFRISO EURO INDEX, Multilyzer Industries). It was found in the range of 18–2 and 1–3 ppm respectively and within safe limits as recommended by the WHO [24].
