Performance Evaluation of Improved Biomass Cook Stove

In developing countries like India, cooking is mainly considered as responsibility of women, who spend a substantial amount of their time in preparing food for their families. Cooking is done by using traditional practices like chulha in villages and modern practices like Induction cooktop, LPG burners in cities. The proportion comparison shows chulha are greatly used with biomass fuel like wood log, crop residue, and cow dung as fuel. Cooking using biomass leads to soot, soot, haze, dust, black smoke, black carbon, fine particles, and ultrafine particles as by-product. These by-product leads to environmental pollution and along it is also harmful to human beings causing lungs diseases. In order to minimize environmental pollution and too lungs diseases it is prime important to utilize fuel in more efficient way minimizing pollution and maximizing heat produced. This paper, focuses mainly on the role of cook stoves in reducing emissions, eliminating drudgery, and improving overall quality of life. The work is carried out to design improved biomass cook stove and performance of improved biomass cook stove is evaluated using thermal efficiency, cooking duration and specific fuel consumption. The water boiling test demonstrates improvement in burning rate, thermal efficiency and specific fuel consumption of improved biomass cook stove in comparison with three stone traditional cook stove, leading to saving of annual thermal energy by 2.2GJ.
