Bark fuel value of important pulpwood species.

Fuelwood characteristics of selected indigenous tree species from central India

Estimating effective heating value of wood or bark fuels at various moisture contents.

SUMMARY In the current world situation of diminishing, irreplaceable, fossil fuels, trees planted for fuelwood, charcoal or derived chemical fuels offer a partial solution to a crisis that, depending on the country, already exists or is very near. The paper describes the types of plantation that may be suitable in varying situations from large Government or commercial industrial blocks to small rural community woodlots and individual farmers' hedgerows or home fuel plantings. An ideal sequence of research to develop an acceptable management package includes site assessment, species and provenance trials, silvicultural trials and either pilot plantations or extension and training services but in many areas the problem is so intense that immediate action is necessary, based on the best information available. In addition to survival, resistance to adverse factors, and fast growth, species characteristics to be evaluated include several wood properties that affect heating value, sparking, odour, ease of handling, cutting and burning; also, for many rural situations selected species would provide other services or products, e.g. shade, shelter, food, fodder, soil stabilization or enrichment plus, in some cases, poles and light timber. Seeds should be available and local supplies (of genetically improved material where possible) should be established but good coppicing ability will reduce the problems of establishment of a second crop.

Selection of species for fuelwood plantations.

This report summarizes qualitative information on 5 potential Florida fuelwood species: slash pine, sand pine, melaleuca, eucalypt, and casuarina. The important factors affecting the quality of fuelwood for industrial applications are briefly discussed. Fundamental properties relating to the fuel quality of these 5 potential fuelwoods are synthesized from several published and unpublished reports. Based on the qualitative data shown in this report, it appears that the fuel characteristics of these 5 species are comparable or superior to those of many other woods evaluated in the literature.

Qualitative evaluation of fuelwood in Florida —A summary report

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).
