dc.description.abstractThe article evaluates the minimal initiation temperature and hot surface temperature of the spruce dust layer using selected ignition sources. The influence of selected physical properties of wood dust, the size of the contact area between the ignition source and the combustible material, the ignition time, and the thermally degraded area are monitored. The article describes the behaviour of a 15 mm beech dust layer (Beech Fagus silvatica L.) under the action of three potential initiating sources: a hot surface, an electric spiral, and a smouldering cigarette. Prior to the experimental determination of the minimum ignition temperature, the dust moisture was determined and the sieve analysis was performed. The lowest minimum ignition temperature on the hot plate was 280 °C. The ignition mechanism of wood dust was comparable for all initiators investigated, differing in the ignition time and the area of the thermally degraded layer. The least effective was the initiating source of the smouldering cigarette.en_US
