Fire is a thermodynamics problem, so it relates to area and volume, not gravity.
Gravity does impact creature size, however. A lower-gravity environment supports larger creatures, higher forces creatures to go smaller. Thought is a chemical process though, so that would have a minimum size as well.
I’ve never heard that before! It’s interesting.
I think it depends a ton on environmental conditions. Could combustion on planets with different gravity and pressure take place at different scales?
