ABSTRACT

This work deals with the development of an improved wood cook stove with improved efficiency and emissions, both of which are very sensitive to the combustion chamber shape, material, wall diameter, and cook piece placement. Experiments on this stove have been carried out at the Renewable Energy Lab, Indian Institute of Technology (B.H.U.) Varanasi, India (25.2807° N, 82.9557° E) over a long span of time. Thermal performance and flue gas emission of carbon monoxide (CO) and carbon dioxide (CO2) have been investigated. The stove has exhibited conversion efficiency in excess of 12% because the flame at the exit is well focused. An improved biomass cook stove can save about 190 kg of CO2 annually. Improved wood stoves are eco-friendly in nature and suitable for the cooking requirement in rural areas.
