Stop by the municipal power plant in Marshall if that's near you and ask to purchase a few tons of their stoker coal (i'm not sure if they're still running the spreader stoker plant); although try a bucket first. PM me if you have trouble finding a coal source, i'll try to help. Years ago, lots of good missouri high sulfur coal was mined from trenton to brookfield and west along 36; not so anymore. A proper setup is important; 8" connecting pipe and min 8" flue. a stoker boiler/furnace would be best, but they're more $$ and harder to find. Regardless, that bit stoker from a spreader-stoke plant like the one in marshall will burn very nicely in your coal-burning fireplaces if you've still got the grates etc.
Can you still get coal from the mines in Southern Illinois? It is really good, hot coal. When I lived in Marion, Ill, that's what I burned there.
