I have no idea! I do know that my coal is some of the last deep mined pea coal from Superior. It is 100% hard glassy coal with very little fines. It is very dry. It is kept under cover so the rain never sees it, then once a year it is moved into my bin that holds a years worth. That is in a vented room under a shingled roof. It's not wet, not damp, it doesn't even have bird pee on it! That being said, I'd venture a guess that any and all coal has some hydrogen and oxygen in it....but maybe not. Maybe, perhaps, just the air that feeds the fire carries vapor enough to show out the chimney. I'll bet that's a better guess than water IN the coal. Ya! That's my story & I'm sticking to it.
