For a long time, hand-fired equipment was the only game in town...so rice & buckwheat had no market. I am surprised that there is even much of it still around, considering the co-gen plants that burn it and the market for the smaller sizes.

Years ago the smaller coal (rice and barley) and some of the larger junk coal were placed on the bank beacause they were not premium coal. Rice was not used in the railroad or steel industy, it wasnt even used in home heatng until many years later when boiler manufacturers decided to develop a use for it. So it sat on the banks sometimes at deserted mine pits, and old wash yards. It is now being blended with fresly mined coal. Same hold true with silt, no use for it until congeneration was developed. I hope this helps.
