A STUDY OF THE UNPILOTED IGNITION OF PLANAR SURFACE PONDEROSA PINE.
Abstract
The unpiloted ignition of wood caused by thermal radiation varies widely when only small areas of the test panel are irradiated. In order to make a comparison of the effect of a given variable, which in this case was water content, a statistical method was devised which yielded a 50% probability of ignition point as a standard of comparison. The results of the testing were predictable at higher water contents in which the requisite heat flux to produce produce ignition was an increasing function of increasing water content. At extremely low water content an unexpected increase in the requisite heat flux required for ignition was observed. While several explanations are possible to account for the observed anomaly, selection of any one exclusive explanation was not made due to the lack of sufficient data. (Author)
