Effects of Carbon and Other Contaminants on Ignition of Lubricants in Compressed Gas Systems.

Abstract

The effects of carbon and other contaminants upon ignition of lubricants in compressed air and oxygen were investigated in a compressed gas flow system developed by this laboratory. It was found that carbon, the metallic oxides such as ferric oxide and cuprous oxide, and the combinations of carbon with the metallic oxides all exerted an influence on the ignition temperature of a lubricant. Ignition temperature of a lubricant was found to be a complex function of system pressure, gas flow rate, materials of construction, gaseous environment, and amounts of lubricants and contaminants. With regard to the effect of contaminants and system materials, Monel was found to be preferable to stainless steel from the standpoint of hazard reduction. Although the mechanisms of material ignition in oxygen and air were similar in many aspects, further investigation into ignition in each atmosphere is still necessary. (Author)
