An experimental study was conducted to characterize erythrophleum suaveolens (Gwaska) charcoal. The test was conducted for proximate analysis (involving the determination of moisture content, ash, volatile matter and fixed carbon) and ultimate analysis (involving the determination of carbon, hydrogen, oxygen, nitrogen sulphur and calorific value) of erythrophleum suaveolens charcoal. The determined values of moisture, ash, volatile matter and fixed carbon were 0.94%, 6.13%, 6.77% and 86.16% respectively. Also the determined values of carbon, hydrogen, oxygen, nitrogen, sulphur and calorific value were 77.5%, 9%, 5.48%, 1.89%, 0.003% and 7158.6995 Kcal/Kg respectively. Therefore, the gwaska charcoal satisfies the blast furnace requirements for moisture, ash and sulphur in Nigeria. However, its volatile matter exceeds the specified limit except for Indian standard practice. The erythrophleum suaveolens charcoal’s thermal properties showed that it could compete favourably with coke and therefore can be an excellent reducing fuel for the production of iron.
