Abstract
A low cost heat-conserving stove that uses palm waste briquette (substitute for fuel wood) has been developed. It has a furnace size of 400mm diameter and a height of 400mm with a 90mm inner cylindrical burner. The heating surface of the stove generated about 966 kilojoules of heat. A natural draught of 6m/s (efflux velocity) was used to determine the chimney size. The stove which was designed and fabricated mostly from 3mm low carbon steel (mild steel) material can accommodate different sizes of briquette for both domestic and industrial cooking. The air inlet has a regulating duct that controls the burning of the briquette. The burning rate of the palm waste briquette using the briquette stove was estimated to be approximately 3.0kg/hr. This value was found to be lower than values obtained when the same quantity of briquette was burnt in the open air. The technology is recommended for adoption by women preparing snacks (such as roasted yam. plantain and corn) in market places and along commercial roads.
