Anthracite Coal 25,000,000 BTU's per Ton or 12,500 BTU's per Pound
#2 Heating Oil 180 Gallons equals 1 Ton Anthracite Coal
Natural Gas 26,080 Cubic Feet equals 1 Ton Anthracite Coal
(1035 BTU'S equals One Cubic Ft.)
Electric 7325 Kilowatts equals 1 Ton Anthracite Coal
Propane Gas 298 Gallons equals 1 Ton Anthracite Coal
Wood Pellets 13,500,000 BTU's per Ton 46% less than Anthracite Coal

Just some numbers to play with. (grin)

Thanks for that, real interesting!

The btu. Value on the rubber is a surprise? Now someone just has to figure out how to make a new forge that can burn an old Firestone(grin, pun intended) smoklessly !

This could be brilliant for the environment.........  Just make sure you get it to the patent office real quick. :)

Actually the rubber dust they create when grinding the old tread off a tire in preparation for recapping can be used as a heating fuel in a pot belly stove. Smokes like crazy until the top surface chars then is then mostly smoke free. After the initial loading to the stove, the remainder can be added a shovel full at a time with much less smoke. I am not sure you could do that today with much stricter laws and nosy neighbors.

I remember years ago there was a company in the US that was going to "recycle" old tires as the heat source for processing Portland cement. They planed to grind up the tires and use them as the fuel to fire the big kiln to cook the limestone.  After the EPA changed the regs it made it just about impossible to do it any longer in the US and the company moved its plant out of the US.
