I have a Combustioneer Mk IV, Bit coal "furnace". Which requires Bit pea. I get most of my coal from;
Central Fuel Co Wash Plant $95/Ton
2458 Shadyview Rd SW, New Philadelphia, OH 44663http://kimbleclay.com
20 miles south of Canton OH, New Philadelphia exit off of I77
This is a wash plant and not set up for sized stoker coal. Though I have talked the plant manager to "make" pea for me. What he has done is put a screen at the end of a chute that allows pea through. The caveat is, stock up before winter hits.
