Authors: Igboanugo A.C, *Ajieh M.U
An improved biomass stove was designed, constructed and its performance was evaluated. The uniqueness of the stove is its portability, and insulated combustion chamber. In addition, a conical flame collector was introduced with vents for ease of circulation of primary and secondary air. Stove performance was based on the heat transfer efficiency, percentage heat utilized, fuel consumption and burning rate. Water boiling test was conducted in accordance with University of California Berkeley (UCB)/Shell Foundation method which is based on ISO/IWA/VITA WBT 4.1.2 standards for testing the efficiency of wood in stoves. The improved biomass stove (IBS) had a maximum thermal efficiency of 55% compared to 18% for the traditional three-stone stove while the percentage heat utilized (PHU) was 54%. The introduction of secondary air inlet through the combustion chamber enhanced heat retention and increased fire power during cooking.
