Energy conversion efficiency of pressurised kerosene and pyramid-shaped clay-lined charcoal cooking stoves

Abstract

This paper evaluated fuel utilisation in cooking stoves. The cooking stoves used for the experiment were a pressurised kerosene stove and a pyramid-shaped clay-lined charcoal stove. Comparison tests were conducted and their results analysed to determine the efficiency of the stoves. The specific fuel consumption of the pressurised kerosene and clay-lined charcoal cook stoves per kilogram of food were obtained as 48 680 and 28 302 kW/kg respectively. The thermal efficiencies of the stoves were 60.18% for the pressurised kerosene stove and 51.35% for the clay-lined charcoal stove. These results indicate or confirm that the pressurised kerosene stove has the highest efficiency.
