fifoenergy.com says 35.314 cubic feet per 1 ton of bituminous coal. My coal supplier tells me to figure about 36 cubic feet for my antrhacite pea coal wikiansw…ers says about 40 cubic feet per ton of antrhacite.
Because it is a rock, not a mineral, the Mohs value will vary significantly from sample to sample. An average range would be between 3.0 and 3.8.
Anthracite is mostly found in east-central and northeast Pennsylvania in highly folded rocks. Most veins are difficult to mine as they are at high angles and not in flat… deposits. This coal was formed during the carboniferous (Pennsylvainian) era ~ 300 MYA. Small deposits are also found in Arkansas as well as China...but the vast majority is in Northumberland, Schuylkill, Carbon, Lackawanna and Luzerne Counties of Pennsylvania
20 Million BTU ****************** The heat content of coal varies. Bituminous coal typically has a gross heating value of 30,600,000 BTU per ton. The net heatin…g value is 26,000,000 BTU per ton, assuming 85% efficiency. If you need more precise information, go to the U.S. Department of Energy website at www.doe.gov and search on the heat content of coal. -ecn

Anthracite coal is used for steel making.
Within reason all woods have a potential BTU value of 8000 BTU's per pound. Oak, Ash, Balsa and Pine all have the same potential. I am sure there are some exotic woods that mi…ght violate this rule but for the sake of this question 8000 BTU/Pd will do nicely. The term potential is a theoretical maximum yield and, in a practical sense, can not be achieved except in the laboratory. The key is in the weight not the species. Wood, when alive and green, has approximately 50% moisture content. Obviously, water will inhibit the conversion to heat so actual, aka possible, BTU's available to heat a home will drop according to the moisture content. When the moisture content drops to less than 20% the available BTU's will be approximately 6000 BTU's per pound. Seldom, if ever, will the average homeowner achieve greater than this as they have no control of moisture content of whatever they are burning. Some wood pellets will perform a little better than raw wood as they have a binder that holds the pellets together like paraffin or other organic binders. Not all pellets use a binder rather they rely on tremendous forming pressure to maintain their shape during transport and handling.
12,000 BTU equals 1 A/C Ton.
Anthracite coal is harder than Lignite.
A 2.5 ton A/c is the same as 30,000 BTU's 1 ton = 12,000 BTU's
