Abstract : Cooking with traditional three-stone fires is inefficient and detrimental to health and the environment. Biomass gasification presents a promising alternative for clean cooking in developing countries. This study focused on the development of an enhanced biomass gasifier charcoal stove optimized for performance. A bottom-up fabrication approach was employed to design components like the combustion chamber, grate, insulator, stove body, etc. using mild steel and stainless steel. Engineering design parameters related to cost, safety, and thermal properties were incorporated. Finite element analysis simulated structural integrity and heat transfer characteristics. The stove achieved 42% thermal efficiency during cooking tests, exceeding traditional stoves. Emissions were lower than conventional cookstoves. Easy ignition, combustion control, and reduced fuel use were observed during preliminary user evaluations. The improved gasifier design enhances efficiency, lowers emissions, and facilitates adoption. With further refinements, the stove can enable the transition to sustainable cooking solutions, improving livelihoods in developing regions.
