Hydrogen makes up about 70% of syngas; how much oxygen mixed in will cause an explosion? Other conditions can be ignored.
The last edit to this post was made by qugd on 2016-2-3 at 13:26. The explosion limit for ordinary gases is determined using air as a standard, and oxygen makes up about one-fifth of air; based on this proportion, an approximate calculation can be done. The explosion limit of hydrogen is quite wide; around 5% oxygen mixed in can already be dangerous, as the upper explosion limit for hydrogen is around 75%. Additionally, the explosion limit of carbon monoxide in syngas is also quite wide. If oxygen gets mixed into hydrogen, it’s better to run away quickly; otherwise, death is inevitable.
I did some calculations: 4.0% to 75.6%. 4.0% is still acceptable, but 75.6% represents a negative value, which means it constitutes explosive gas. :Q
