I'm from Wyoming, and burn bituminous coal in a hand-fed stove. A stove dealer in South Dakota had a great idea for loading coal into the stove. He said just load a paper grocery sack with coal, roll the top of the bag shut, and toss the whole thing into the stove. Tried it yesterday and it worked great. Beats trying to dump it into front-load stove from bucket or handling it a shovelful at a time.
So, we now say "paper" when they ask us for "paper or plastic?" at the grocery store.
Also, another dealer in Montana had an idea of how to burn the fines/powder. They just get empty milk cartons (not jugs), open the top, and scoop the fines into the carton. When they throw the carton into the stove, the "waxy" part of the carton holds the fines together. Not sure if it works, but I plan to try it.
