In short, No. Coal comes in the middle of the pack when fuels are compared. Propane produces 21500 BTU per pound, Gasoline 17500 BTU per pound, Coal between 12,000 BTU per pound (Anthracite) to 10,000 BTU per pound (Bituminous) and wood (dried) 7000 BTU or so. On the other hand, Coal can be converted to Gasoline using a process developed during WWII, or to Methane (modern) or to "Town Gas", a mixture of Hydrogen and Carbon Monoxide.
40.2 bushel of corn to a ton of wood pellets
Wood pellets are expressed in Btu's per lb. The typical is 8400/Btu's/lb.1 BTU = 251.995761111111 CaloriesOne Ton of Wood Pellets would be 8400/lb times 2000 lbs or 16.8 million Btu's/ton 16.8 million times 252 is the gram calories.Typically though to understand the heat comparison it is best to compare the heat given per million BtuWood Pellets are 8400 Btu's/lb. or 16,800,000 Btu'sPropane gas is 91,600Btu's/gallon according to the American Gas AssociationOne ton of pellets is equal to 183 gallons of propane.#2 Fuel oil is 139,000 Btu's/gallonOne ton of Wood Pellets is equal to 121 Gallons of #2 fuel oilIf your propane is selling for $2.50/gallon you are paying $35.90/million Btu'sIf your paying 225.00/ton of wood pellets you are paying $17.40/million Btu'sIf your paying $3.50/gallon for fuel oil you are paying $ 32.51/million Btu's

Typically the heat value is 8700 BTU per pound. This is for a premium pellet at less than 7% moisture. So, about 348,000 BTU per bag. Rule of thumb, I go with 8500 BTU per pound, as not all manufacturers can guarantee Moisture after it is delivered to the Retail sector. Pellets can pick up additional moisture if not stored properly!

According to the Forest Products Laboratory, #2 Fuel Oil has a Net Heating Value of 115,000 Btu/gal and Premium Wood Pellets have a Net Heating Value of 13.6 million Btu/ton. Btu is a unit of energy to describe the heat value of fuels. From an energy standpoint it would take 118.26 gallons of #2 Fuel Oil to provide the same heating energy as one ton of Premium Wood Pellets. 118.26 gal of fuel oil x 115,000 Btu/gal = 13.6 million Btu = one ton of wood pellets At 50 bags per ton, this equates to 2.36 gallons per bag of wood pellets. ................................................................................................................. Sorry but #2 heating fuel has between 138,700 and 141,000 btu/ gallon , not 115,000. ................................................................................................................. Another edit: The Building Performance Institute and other sources generally give #2 heating oil a heat value of 139,000 BTU/Gallon, but that's not the whole story. Most oil furnaces have a combustion efficiency of about 84%, although this can vary. 139,000 BTU times .84 is ~117,000 BTU. So the original poster was pretty close to right in terms of heat delivered when a gallon of oil is burned, but the second poster is right in terms of the total heating value of the oil if it has a 100% efficient combustion. Once combusted, the heat distribution system efficiency must be looked at. Are you heating an uninsulated basement rather than your living space? Likewise, there are a range of numbers found on line for the heat value of wood pellets. I've seen from 13.6 to 16.4 million BTU. It depends on the quality of the wood pellets, and "Premium" pellets in one region may not be the same quality as "Premium" pellets in another. And once you have your bags of pellets, you have to account for the combustion efficiency of the pellet stove in order to figure out how much you'll really get. One source claims that older models burn at about 65% efficiency, while newer ones burn at 80%. Sealed combustion, with combustion air coming from outside, is generally more efficient. And again, how efficient is the distribution system? Most pellet stoves are in the living space, rather than in the basement, which would be typical of an oil burning system, and this may or may not overcome the distribution system losses.
