Does fire burn hotter/more easily if the oxygen % in the atmosphere is higher?

1.01K views

Been thinking about different atmosphere’s for sci-fi planets and the like, and I know that (allegedly) if there was 5% more oxygen on earth, then bugs and insects would grow to be much, much larger. Apparently the higher oxygen concentration in the early years of our planet is why there was so much megafauna (smth about cyanobacteria?), but how would that affect the way things burn? Since oxygen is incredibly flammable, I would assume that more oxygen = bigger flame, but usually that’s pure oxygen.

tl;dr

How does oxygen concentration affect the way things burn?

If you soak cotton wool in liquid oxygen it will pretty much explode when lit. https://youtu.be/C0U4_k1iO6w

The more oxygen available the faster things will burn.
