What is the lowest temperature for the reaction between sulfur and oxygen?
Thread Content
In the design, there is a liquid sulfur tank with a temperature of around 150 degrees. One of the methods for measuring the liquid level involves using air for backflow; I wonder whether liquid sulfur at 150 degrees will react with the oxygen present in that backflow air What is the lowest reaction temperature for sulfur and oxygen without ignition? Thank you

The substance that catches fire is not necessarily liquid sulfur; it could be sulfur powder that has adhered to the inner walls of the equipment after sublimation, or it could be caused by the spontaneous combustion of ferrous sulfide. Self-ignition of liquid sulfur pipelines and equipment due to sulfur leaking out over time is a more common occurrence.
