Development of Emission Factors for Coal Cook Stoves Used in India
Abstract
Coal is used widely for domestic cooking in many regions of India, which contributes significantly to the Carbon Monoxide (CO) and PM2.5 levels, both to the indoor as well as the ambient air. Modeling and inventorization efforts require the use of Emission Factors (EF) for cook stoves, which are often not available, or represent emissions under steady state combustion conditions following some end-use specific protocols. However, field and laboratory investigations on coal cook stoves in a mining region of India revealed that the emissions were more severe during the initial ignition unsteady state phase. The contribution from this phase varies greatly with the region-specific stove type and user practices. In the present study different types of cook stoves were tested, and the PM2.5 and CO emissions were measured for the entire cooking cycle from the initial ignition stage to the final stage of extinguishing the stoves. EF's were developed, and may be used to include the influence of local ground level sources on the ambient air quality. Choices of local stove type and suitable coal/coal-based fuel may be made using these results for air pollution abatement efforts.
