I was curious of the same thing. I'm familiar with two businesses, both in CT, that truck in their own bituminous from the mines on 20 ton semi trailers. Both use it in steam engine applications. I've always wondered if there is a way to buy any of the power plant coal or other specialty coal that is brought in by barge or rail in New England. When you start making calls you get the quick hustle off the phone because you're not buying in the thousands of tons. I think the only way to get reasonably priced coal of either bituminous or anthracite is to truck it in yourself at 20 tons a pop and store it somewhere or divide it up among your friends. Anthracite in our area will run you at least $350 a ton and at that price it's not worth the hassle over gas. At around $120 a ton for quality bituminous trucked in and delivered, you're saving real money, I don't care how dirty bituminous is!
So, bottom line, build a humongous bin and you are all set! I've spoken with a bunch of mines and they are more than happy to sell you 20 ton loads either you provide the semi or they will arrange it. Costs the same either way. If you had a trucker friend with a gravel type dump trailer at his disposal for a day, you could get the coal for the price of fuel, a couple of meals, a case of beer, and what the mine charges. In other words very, very cheap! I am so jealous of all you guys that have a bituminous mine down the street!
