Performance Evaluation of a Modified Briquette Stove.

Abstract

This study was undertaken to modify an existing briquette stove and to evaluate its performance with briquettes produced from a composition of groundnut shell, almond shell and rice husk. The existing stove had several deficiencies and needed modification to perform better. The modified stove was fabricated using locally available and standardized materials. Design principles as stated in literature were taken into consideration and recommendations made by previous researchers were also carefully taken into consideration in order to improve the stove’s efficiency. The moisture content of fuel (briquettes) used for testing was found to be 14%. The efficiency of the stove was determined using simple water boiling test. The efficiency was estimated to be 57.2%; time spent to boil 1.580kg of water was 12 minutes from hot start, the specific fuel consumption of stove was found to be 0.577kg/kg. The results obtained from this study compares favourably with similar stoves in existence
