Source Model of Domestic Gas Stoves

Results from medical research show that the use of domestic gas stoves could have a major impact on human health and well-being, especially if they used for heating. Approximately 0.289 m3 of natural gas is combusted daily in Hungarian kitchens. The users normally stand near the stove during its operation, which on average is 45 minutes long; therefore, they are directly affected by the combustion products. Nevertheless, uncertainties remain concerning the effects of the combustion products on humans; the nitrogen dioxide load could be the most problematic. Its nominal source strength is in a range of 12.0 - 21.0 ug/kJ, depending on the type of burner. In order to improve kitchen ventilation, a source model of domestic gas stoves has been developed that is based on measurement results, statistical data, and further technical assumptions.
