Abstract [en]

To obtain experimental values for ignition of moist wood experiments were conducted where moist medium density fiberboards with varying moisture contents were ignited using a cone calorimeter. The cone calorimeter used a spark as means of ignition. Theoretically ignition times were predicted using the finite element code TASEF.These values were then compared with the experimental ones. The ignition was simplified to be a purely thermal problem where the boards will ignite when they reached a certain temperature. The initial assumption was that the surface ignition temperature was 350 ⁰C for all incident radiation and moisture contents The results indicated, however, that this was not a viable assumption. Instead it was found that an ignition temperature of 200 ⁰C at a depth of 1mm may be an alternative to use when predicting the ignition time.
