There’s two things you need to distinguish here: “Fire” and “flame”.

“Fire” describes the actual chemical process of fuel burning away. “Flame” is the visible result of that burn, just the water vapour and carbon monoxide/dioxide that result from the burning, so hot they glow.

If the flame gets hot enough, some parts of it might turn into plasma, but that’s not universally true.
