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.
