Hi there!
here's the answer:
Every fuel burns i.e. undergoes combustion until there is fuel left to combust properly.
Initially, Wood, coal and other solid fuels burn with a flame because in there is sufficient amount of fuel in the beginning to undergo a fairly efficient combustion reaction.
As more fuel gets burned, there is not much fuel left for an efficient combustion reaction to take place. So, they turn into Embers (the part where fuel only glows without a flame), thereby resulting in heat and light energy). There will be residue (mostly ash) left behind after fuel has burnt. This residue/ash blocks further efficient combustion.
:)
hope it helps
