  • Biomass Burn Characteristics - Ontario

    For example, most agricultural residues have heating values that fall in the range of 14–19 MJ/kg (6,040–8,200 BTU/lb); coal ranges from 17–30 MJ/kg (7,300–1,3000 BTU/lb). Moisture Dry biomass has a greater heating value (or net energy potential), as it uses little of its energy to evaporate any moisture.

  • Wood species type BTU values of a cord for burning wood in

    Wood species type BTU values of a cord burning wood in a wood stove. As you can see from the chart below, the famed red oak is not the highest on the list. It is surpassed by 13 other varieties that have as much as 37% more BTUs per cord! This can mean much longer burn times and less loading. If you have this type of wood available, save it

  • Firewood - BTU Content by Tree Species – OutdoorBoiler.com

    What is the BTU content of firewood? A full cord of wood is a stacked wood pile that is four feet wide by four feet tall by 8 feet long - 4'x4'x8'. It is therefore 128 cubic feet but because of air space between pieces the actual amount of solid wood may be only 70-90 cubic feet. This depends on the size and shape of the pieces and how tightly they are stacked. Because of this variable

    percent decrease in heating value. The other factor affecting heat content is the tree species of the wood. Higher heating values of wood can vary from 8,000 to 10,000 Btu per pound, bone dry. A cord of wood is a rough measuring unit; it is a stack of wood 4 feet high, 8 feet long, and 4 feet wide. A "good" cord of wood will be tightly packed.

  • Tips & Advice for Heating with an Outdoor Wood Boiler

    The amount of heat per cord of dry wood is presented in Table 1. Heat content is shown as a percent of dry green ash, a fairly common, dense firewood. Values above 100 signify a higher heat content than green ash and below 100 a lower heat content. Table 1 also contains information on other characteristics that determine firewood quality.
