From what I remember of coal fires :-) the relevant fact about a coal riddle would seem to be that it is operated by being pushed vigorously in and out (or back and forth); this action causing the ash to fall through the grid, and leaving the coals above the grid and thus exposed to the updraft, and able to burn hotter because no longer smothered by the ash. (Freudian, eh?)
