Title: % of Oxygen to support combustion
Post by: johnLeong on July 15, 2009, 11:13:43 PM

Hi all,

I would like to seek some suggestions here. What is the % of oxygen in the ambient air can start a combustion with sulphur powder under milling process at normal condition. The operation is about 50 degree C.

Thank you.

Hi johnLeong,

I was not able to find the minimum oxygen concentration for combustion.

I did find an experiment though... http://www.angelo.edu/faculty/kboudrea/demos/burning_sulfur/burning_sulfur.htm (http://www.angelo.edu/faculty/kboudrea/demos/burning_sulfur/burning_sulfur.htm)

To be safe, you may want to outsource this test to a laboratory and have them perform a study on this value.

To be safe, try and minimize (eliminate if possible) atmospheric oxygen to minimize the risk of this occurring. Since we are human, it is always best to minimize the risks.

Best of luck,

Eugene
