An investigation was carried out on the use of sawdust as fuel for firing oven. An oven was fabricated and fired with sawdust from four selected wood species (Triplochitus scleroxylon, Milicia excelsis, Khaya sinegalensis and Celtis zenkeri).
The temperature of the oven was measured at four different levels. The results indicate that the temperature of the oven increases with the degree of hardness of the wood species and nearness to the heat source. The temperature was the highest for khaya sinegalensis followed by milicia excelsis, celtis zenkeri and triplochitus scleroxylon, respectively. The average temperatures recorded for the species in that order were 209.62, 173.50, 166.37 and 104.19°C. Statistical analysis of the data obtained indicates that the separate and interactive effects of all the factors (duration of heating, location and wood species) were significant at 99%.
