Abstract:

An experimental apparatus has been built to investigate the ignition of surfaces as a result of impact with burning embers. Embers were simulated by machining wood (pinus ponderosa) into small disb of uniform geometry. Ember simulation was necessary since it is difficult to capture and characterize embers from an actual burning object. The ember ignition apparatus was installed into the Fire Emulator / Detector Evaluator (FE/DE) to investigate the influence of an opposed airflow on the ignition propensity of a surface. The operation of the ember ignition and release apparatus is described.
