Bulk density of seven typical industrial wood fuels

The bulk density and delivered moisture content (MC) of wood fuels is important in determining the haul load and Btu value of various fuels. Fuel yard managers and wood fuel producers need to know the Btu content of various fuels under certain conditions. Seven types of wood fuel were measured, in an industrial setting, to determine the density of each type of fuel. The type, density, and MC of each fuel was: pine whole-tree chips, 18.8 pcf @ 40 percent MC; hardwood whole-tree chips, 20.4 pcf @ 35 percent MC; mixed pine-hardwood sawdust, 23.1 pcf @ 41 percent MC; hardwood sawdust and bark, 25.8 pcf @ 45 percent MC; hogged dry furniture waste (mixed hardwoods), 15.7 pcf @ 12 percent MC; hardwood pulp chips, 22.9 pcf @ 43 percent MC; and hardwood shavings, 10.8 pcf @ 8 percent MC. Dry weight density is also reported for each fuel type.
