Abstract
The objective of this work is to provide information about combustion characteristics of a small piece of wood exposed to high temperature air stream. The experiments have been carried out by using four kind of woods with different densities. Ignition times and burning times of wood samples were measured by varying the shape, size and the moisture content of them. The air temperature was varied from 530 to 875°C, and the air velocity from 0.9 to 7.2m/s, and the moisture content from 0 to 57%. The results indicated that the ignition time was extremely influenced by the temperature, the velocity and the moisture content. The effect of the velocity and the sample weight on the burning time was remarkable, and the temperature had little influence.(τi+τb) /W versus water content was a near linear function.
