It is a major health concern for the people who uses biomass as fuel for cooking in the rural residential kitchen of the developing countries. The quality of life is greatly affected due to exposures to exhaust flume. In this study, a typical single burner conventional stove was used to model a rural kitchen. The overall dimension of the model kitchen is 3.50 m × 2.20 m × 1.85 m. A three-dimensional CFD code was adopted to perform steady state simulations with appropriate boundary conditions. A very reasonable agreement between present numerical results and the experimental data was obtained. Numerical accuracy was tested for optimum grid as well. In this study, varying intensity of emissions of CO, CO2 and particulate matter (pm) from different kinds of bio-fuels burning have been investigated. Dispersions of these pollutants in the kitchen space have been investigated for without ventilation and natural ventilation without hood and with hood systems. It has been observed that CO, CO2 and pm concentration exceed by significant amount than the safe threshold for no ventilation case. Introducing natural ventilation of the burning exhaust through the roof top chimney does not even keep the concentration within the safe limit. However, a significant improvement was observed under natural ventilation for the kitchen with the addition of a hood along with the roof top chimney.
