Most of the heat from a typical fire involving solid fuel is produced by radiation or convection?

I don't know, but keep in mind we can't do your homework for you. I don't know if this is a homework question for you or not, but I'm sure many will see it that way.

Maybe you can give us YOUR answer and your reasons, and we can help you work through it?

Its not homework, just one of those niggling question I should know, but can't decide, I think it's convection

In any fire, almost ALL heat is initially released as photons -- electromagnetic radiation in the infrared or in the visible spectrum. In other words, it's radiation. Some of the radiant heat is absorbed by the air and can, thereafter, be dissipated by convection or conduction. It can also be re-radiated by the air molecule's emitting a photon. If any photons aren't absorbed by air, they'll eventually be absorbed by solid surfaces or radiated into outer space (not much of that will happen).

So, I have a hunch that your question anticipated a different answer.
