Biomass fuels in this study are pig excrements, wood charcoal, sawdust and these mixtures. The bench scale combustion furnace is a rotary kiln furnace with electric heating. A method of fuel feeding is the batch method. The temperature on the inner wall of the furnace is set on 550℃. When the fuel is burning, time-series data of important quantities, such as the temperature on the furnace wall, the temperature of combustion gas and components of combustion gas, O2, CO, NO and other, are measured. It is experimentally shown the effects of the composition of biomass fuels on burning behavior and the difference of rates of combustion between wood charcoal and pig excrements. Furthermore, the thermal analysis such as DTA and TG of these fuels is conducted. The DTA curves have two peaks, and the second peak at higher temperature means the combustion of solid carbon. The second peak of pig excrements is shifted to higher temperature than the second peak of wood charcoal.
