Development and Exergo-Economic Analysis of a Gasifier Cookstove with Thermoelectric System

This study presents the development and exergo-economic analysis of a biomass gasifier cookstove integrated with a thermoelectric generator (TEG) for generating electricity from waste heat. The design utilizes biomass as a fuel source, converting it into combustible gases through gasification while capturing waste heat for electricity generation using a TEG. The thermoelectric system powers a fan to improve combustion efficiency. Experimental results show stove efficiencies between 76% and 82%, and the exergo-economic analysis reveals a cost-effective design with high exergy utilization. This dual-purpose system demonstrates potential for improving energy efficiency and access to electricity in developing regions.
