Title Electrostatic charges in oxygen piping due to dust particles in the oxygen stream
Original title Elektrostatische Aufladungen in Sauerstoffleitungen, verursacht durch Staubanteile in der Sauerstoffstr÷mung [in German]
Bibliographic information Heft 22, Moderne UnfallverhŘtung, Vulkan-Verlag Dr. W. Classen, Haus der Technik, 4300 Essen, Germany (Fed.Rep.), 1978, p.95-101. Illus. 17 ref.
Abstract The possibility of accumulation of electrostatic charges and the ignition hazards resulting from solid impurities (rust or scale, metal chips, etc.) in the oxygen network are studied. The experimental model corresponded to conditions found in oxygen-converter steelworks. Measurements related to the effect of length and constituent material of the piping on the electrostatic charge, and of particle size, pressure, or velocity and concentration of impurities on the charge. Conditions for an electrostatic discharge and hazards of oxygen ignition in the piping are considered. Conclusion: while electrostatic charges can accumulate, conditions necessary for ignition caused by a discharge are not met.
