What happens to a burned Elantrian?

[Farnsworth]

In Elantris, Galladon says that "some say, if you burn us and cut off our head, or do anything that completely destroys the body, we'll just stop existing. Others, they say the pain goes on - that we become pain." 

Which is true? Also, after Raoden fixed everything, would a burned Elantrian be healed? Would they just materialize?

[Weltall]

Well, we know that beheading was sufficient to kill Karata because she didn't come back even though she died mere minutes before Raoden 'fixed' the magic so there's no reason to assume an even more thorough destruction of the body would be survivable.

Whether an Elantrian killed by fire is actually dead or not, I don't think we know for sure but I certainly hope it's the former. If beheading is properly death (and there's no evidence that an Elantrian who's lost their head is 'alive but hoed' so I think that's the case) then it's possible there's a Cognitive aspect at work. You think such a thing should kill you no matter what, therefore the Dor can't sustain you. So a burned Elantrian should be dead too under that assumption.

Elantrians heal quickly, and the Dor sustains them no matter how old they become, but Karata's death has shown that they can still die. In fact, Galladon's father even died of something called "heart-death" back in the pre-Reod days.

The fact that some of them believe they'd still be conscious after their body is destroyed, which would be a problem whether the Elantrian is pre- or post-Reod if it was true (though I don't believe it is), could be the reason for that apparently pre-Reod ritual of placing Elantrians in the Pool as a sort of funeral rite. But while it does seem to offer a release from pain in the Physical Realm, what happens to them after transitioning into the violent Selish Cognitive Realm is not a pretty sight...

Maybe this is too simple of an answer, but if it could kill a full Elantrian, wouldn't it be enough to kill a Reod Elantrian?
