Title:          Performance enhancement of cook stove
Authors:    Nandish Gayad, P. G. Tewari
Abstract:   Use of improved, smokeless and energy-efficient cooking stoves still remains a distant dream. One of the oldest and technologically most simple cooking methods ever developed by civilization continues with its perennially archaic status for billions of its users, mostly poor. Consequently, health and social impacts from cook stoves continue to adversely affect the underprivileged. Women and children are the most suffered section of the society due to their time lost in collecting the fuel as well as due to local and indoor pollution. The changing world scenario that includes rising population and drastic degradation of the ecosystems has renewed the demand for much needed transformation of technology of cooking stoves. The design, construction and testing of an improved wood stove is undertaken according to BIS testing of Chulha. The design improvement of the stove focused on the following areas: the design of the combustion chamber, provision of insulation around the combustion chamber to reduce conduction heat loss across the walls of the chamber, incorporation of ash box to remove the ash, provision of sizable and adjustable air inlet to ensure the availability of sufficient air for the complete combustion of the fuel wood. Results showed that the thermal efficiency of the stove is found to be 37.65% with fuel wood consumption of 1.73kg/hr which is more efficient than the existing models.
