We know that light is produced when a charge particle accelerates.
Fire doesn't have electric and magnetic field so how does light come from a fire?

Fire is really a combustion reaction in which a fuel is oxidided by air oxygen. The two so-called half reactions that take place are:
$$\text{Fu}\to \text{Fu}^{n+}+n \text{e}^-$$ $$\text{O}+2\text{e}^-\to \text{O}^{2-}$$
These electron transfers release energy, known as the Gibbs Free Energy of Combustion, in the form of heat energy.
This heat energy heats up the combustion gases and causes them to emit visible light (as well as IR radiation)
What exactly is the mechanism of radiation emission by the hot combustion gases is explained in great detail here.
.
Light is also produced by atomic transitions. This is when an electron leaves a higher (orbital) state and occupies a lower one. You can see it here:
