Experimental Studies on a Forced Draft Domestic Biomass Cook Stove

Abstract

This study presents the design, fabrication, and preliminary testing of a forced draft domestic biomass cook stove. Traditional natural draft biomass stoves suffer from incomplete combustion, higher smoke generation, poor flame stability, and low thermal efficiency. To overcome these issues, the proposed stove uses a bottom-mounted fan/blower to supply forced air into the combustion chamber. This improves oxygen availability, air–fuel mixing, combustion stability, and heat transfer. The stove was fabricated using mild steel with insulation support, and its performance was tested using the Water Boiling Test method. The study focuses on fuel consumption, boiling performance, smoke reduction, and thermal efficiency improvement for domestic biomass cooking applications.
