Experimental and theoretical study of the ignition of timber by an incandescent lamp

In this work, an experimental and theoretical study of the ignition of 20 mm thick paulownia wood exposed to a clear glass envelope incandescent light was performed. The experimental study includes both calibration tests and ignition experiments. Three simple models are established to estimate the incident heat flux in different positions, and the minimum heat flux to achieve ignition, and to correlate the ignition time with distance between the incandescent lamp and the wood sample. Considerable agreement between experimental and theoretical results was obtained in most cases.
