So you are selling your wood scrap for mulch, animal bedding or giving it to the community? Before making the decision to sell your wood waste in the marketplace, it is worthwhile to compare the BTU (or heat content) dollar price of your wood with the BTU price of your gas or oil. We have devised a calculator to make a comparison tailored to your own fuel costs and wood types.
OIL USERS CALCULATE THE VALUE OF YOUR WOOD
The calculations factor in both moisture content of the wood as well as combustion system efficiency to arrive at the fuel's net MBTU heating value.
* Assumptions: 1 therm=100,000 BTU
Commercial Gas Boiler Efficiency at 85%
**Assumptions: Bone Dry Wood = 8500 BTU/lb, therefore
A Ton of Bone Dry Wood = 17 million BTU
Commercial Boiler Efficiency at 70%
***Assumptions: 1 gallon of oil=135,000 BTU input with
Commercial Oil Burner Efficiency at 74%= 100,000 btu per gallon output
