Fuelwood Characteristics of Northwestern Conifers and Hardwoods (Updated)

摘要

This report is an update of the original publication by Oregon State University in 1987 (Resource Bulletin 60). According to agreements, researchers at the U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station and the Juneau Economic Development Council worked with Oregon State University to update this reference concerning wood energy properties. The fuelwood characteristics were reformatted and presented in tabular form, and a literature review was conducted to check for additional information published since 1987. This report provides fuelwood values for 34 conifer and 20 hardwood species found in the Pacific Northwest and Alaska. Values are presented for the following characteristics: specific gravity of wood and bark, percentage moisture content of wood and bark, higher heating value of wood and bark, percentage ash of wood and bark, percentage bark by volume, and ultimate analysis of wood and bark (percentage of carbon, hydrogen, oxygen, nitrogen, and sulfur).
