THERMAL EFFICIENCY AND SPECIFIC FUEL CONSUMPTION OF COMMON HOUSEHOLD COOKSTOVES IN BAUCHI
Publication Date : 01/08/2010
Five different stoves using two biomass fuels, kerosene, liquefied petroleum gas (LPG) and electricity were examined. Fuel and stove parameters were monitored. The result showed that solid biomass stoves have substantially lower thermal efficiencies, higher specific fuel consumption than stoves using liquid and gaseous fuel. In general, efficiencies increases from values of 9.6% for three stone fire using firewood to 78.4% for gas stove employing LPG. Biomass fuels have higher burning rate and specific fuel consumption because the quantity of firewood and charcoal required to raise 1kg of water to boiling point is more when compared to liquefied petroleum gas and kerosene.
