In this paper the explosive and fire properties of energy willow dust were experimentally determined before and after drying with superheated steam at temperatures of 120°C, 140°C, 160°C and 180°C. The conducted research has shown that operating parameters of the installation of drying with superheated steam of the energy willow biomass have a decisive impact on the fire-explosive characteristics of the dust produced. The results indicate that the higher the drying temperature, the stronger the probability of ignition of the willow dust cloud, the faster the flame propagation and the higher the explosion intensity. Although the superheated steam drying installation for energy willow biomass is considered to be safe, the probability of occurrence of a fire or explosion events of the biomass dust-air mixture is likely.

W artykule wyznaczono eksperymentalnie właściwości wybuchowe i pożarowe pyłu wierzby energetycznej przed i po suszeniu parą przegrzaną w temperaturach 120°C, 140°C, 160°C i 180°C. Na podstawie przeprowadzonych badań stwierdzono, że parametry pracy instalacji suszenia parą przegrzaną biomasy wierzby energetycznej mają decydujący wpływ na charakterystykę pożarowo- -wybuchową powstającego pyłu. Wyniki wskazują, że im wyższa temperatura suszenia, tym większe prawdopodobieństwo zapłonu chmury pyłu wierzby, tym szybsze rozprzestrzenianie się płomienia i większa intensywność wybuchu. Pomimo, że instalacja suszenia parą przegrzaną biomasy wierzby energetycznej jest uważana za bezpieczną to prawdopodobieństwo wystąpienia zdarzeń pożarowych lub wybuchowych mieszaniny pyłowo-powietrznej biomasy jest prawdopodobne.
