After a long day or night of burning, there's not much left in the stove; mostly a lot of ash and some crumbly charcoals. However there some hard flat pieces of what I assume are also coals. They're black and almost look like metal welded together. What's up with these things?
 
aka clinkers, slag
 
If there are plates that sit inside near the top of the stove check to see that they are still in one piece. Other than that, it's possible that a piece of furnace cement chipped off somewhere.
 
My dad used to call them clinkers. I seem to recall him saying they come from burning bark. Anyway, we got a lot more of them back in the day with the smoke dragon stoves than I've seen with the Napoleon, although we definitely do get them. I've never tried to burn them, always just assume that they wouldn't.
 
Yup. Clinkers. Through them in your garden.
