I've been told that those objects are from high shale content in the coal, but I had a similar problem last year, they actually jammed the grates on my Harman. I think it's more of a mineral of some sort, There was a reddish cast to the fine ash in the stove. Guess it's strip coal, right?
I posted pictures of the clinkers that I had like that back in February or so, maybe you can find them!
