The design of explosion mitigation strategies e.g. vent design is mainly based on dust explosion characteristics such as the maximum explosion pressure P₍max₎ and the deflagration index (KSt) of dust cloud, which are defined in various standards. The wood dust explosion characteristics can be directly obtained by performing standard tests, and test results are also available in the literature. However, the parameters for one type of dust may vary substantially in the literature. For example, the (KSt) value for one wood dust is 11.4 times higher than another wood dust in Gestis-Dust-Ex database. The reason for such large variation in explosion parameters is due to factors such as material properties, particle size distribution, particle shape, moisture content, turbulence level during tests and so on. The objectives of this paper are (i) to carry out dust explosion tests for P₍max₎ and (KSt) for two wood dusts with well-described material parameters such as particle size distribution and moisture content according to European standards, (ii) to perform statistical analysis of wood dust explosion characteristics including P₍max₎ and (KSt) in the literature, (iii) to identify the effects of dust material parameters such as particle size and moisture contents on P₍max₎ and (KSt) and (iv) to highlight the variation in P₍max₎ and (KSt) and the importance of obtaining knowledge about these properties of an individual dust, e.g. via dust explosion tests.
