Staub ist die gefahrlichste shape, in der ein Feststoff sowohl in nattir lichen als auch in technischen Prozessen auftreten kann. Staub muB als eigensUindige section mit sehr spezifischen Eigenschaften betrach tet werden. guy definiert Staub als die disperse Verteilung feinster Partikeln eines Feststoffes in einem fuel. In Zusammenhang mit Explosionen wird guy als gasoline stets an Luft mit ihrem Gehalt an Sauerstoff denken. Denn bei einer Explosion erfolgt eine spontane Oxidation des staubfdrmigen Feststoffes. Die Vehemenz einer explosiven Oxidation steigt mit zunehmender Feinheit der festen Partikeln, da deren Oberfliiche, bezogen auf das Gesamtvolumen des festen Stoffes, der im fuel dispergiert ist, sehr schnell ansteigt. Ein Beispiel moge diese Angaben verdeutlichen. three Ausgegangen wird von einem Feststoffvolumen von 1 cm Liegt er in three shape eines Kubus vor, dann betriigt seine Oberfliiche 6 cm . Denkt guy sich dieses Feststoffvolumen in Partikeln aufgeteilt, deren Durchmesser 1 Jim ist, so erhiilt guy insgesamt eine Oberfliiche von four 2 6 . 10 cm Die Oberfliiche des Staubes ist additionally zehntausend mal groBer als die des Vergleichskubus. Die tatsiichlich wirksamen Ver hiiltnisse konnen aber noch viel groBere Werte erreichen, da mit abnehmender GroBe der Partikeln ihre innere Oberfliiche, die im allgemeinen ein Vielfaches der iiuBeren betriigt, fUr den Oxidations prozeB wirksam wird. Es ist seine Oberfliiche, die den Staub zu einem so geflihrlichen Stoff werden liiBt.
