Book excerpt: A survey determined that installed dry kiln capacity in Alaska more than doubled to an estimated 220 thousand board feet (mbf) within 4 years (2000-2004). This increased ability to produce dry lumber and value-added products resulted from industry efforts to obtain federal funding to support a dry kiln grant program. This report reviews grantees' progress in implementing grant supported projects and their impact on the production capabilities of the Alaska lumber drying industry. Data were collected in early 2005 by using a standard set of questions asked of 19 dry kiln owners. Much of the growth in drying and value-added processing capacity has been concentrated in southeast Alaska where there has been the greatest dry kiln investment. During 2004, the estimated volume of lumber dried in Alaska was 813 mbf, whereas potential annual capacity was estimated to be almost 6,600 mbf. This indicates that Alaska producers are drying just over 12 percent of their potential capacity. Factors that will increase the future production of value-added forest products in Alaska include a continuing supply of economically priced timber, the ability of the industry to support a reasonably priced grading service, and the ability of producers to move value-added products to domestic and export markets.

This book was released on 2018-03-17 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Air Drying of Softwood Lumber, Fairbanks, Alaska The pile that began drying in May was dry 19 percent moisture content) within a month. The pile that began drying in July had an average moisture content of 18 percent within 70 days, but even then more than 5 percent of the volume had a moisture content 19 percent. The pile that began drying in December still had a moisture content 50 percent after 70 days. Drying rates in summer were correlated with average daily temperature and average daily dew point to derive predictive equations that could be used with daily or monthly averages.

This book was released on 2018-03-19 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Moisture Distributions in Western Hemlock Lumber From Trees Harvested Near Sitka, Alaska This research project is viewed as a first step in developing kiln drying schedules for western hemlock in southeast Alaska. Lumber that is grouped together according to green moisture content can reduce the likelihood of defects resulting from uneven drying. Alternatively, separate drying schedules could be developed for lumber having uniformly high moisture content that would not require sorting prior to drying.

Book excerpt: This report describes how lumber can be air-dried most effectively under outdoor conditions and illustrates the principles and procedures of air-drying lumber that were developed through field investigations and observations of industrial practices. Particular emphasis is placed on the yarding of lumber in unit packages. Included are topics such as why lumber is dried, advantages and limitations of the drying process, properties of wood in relation to drying, layout of the drying yard, piling methods, causes and remedies of air-drying defects, and protection of air-dried lumber.
Download or read book Use of Wood Energy for Lumber Drying and Community Heating in Southeast Alaska written by and published by . This book was released on 2004 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: The inadequate transportation infrastructure and undeveloped markets for sawmill residues in southeast Alaska are among the factors that limit the use of this forest resource. This study considers the potential use of sawmill residues to supply two bioenergy systems that would produce thermal energy for (1) community heating and (2) a lumber dry kiln in Hoonah, Alaska. The proposed community heating system would be a direct combustion system, burning approximately 1,450 green tons (1.315 green metric kilotons) of wood fuel per year to provide heating for seven centrally located buildings in Hoonah. Additional sawmill residues would be used in another system to provide process heat for a proposed 25,000 board foot (41.3 m3) dry kiln. The Hoonah sawmill typically produces as much as 5 million board feet (8,255 m3) of lumber per year, primarily from western hemlock and Sitka spruce. The processing of this amount of lumber would result in an adequate volume of residue to provide a fuel source for the heating requirements of the proposed projects. Wood residue from the sawmill is assumed to be available at no cost other than for transportation. Use of wood fuel for community heating would save an estimated 65,000 gallons (2.47 kL) of heating oil per year. Avoided fuel costs would be approximately $91,500 per year based on No. 2 fuel oil at a market price of $1.40 per gallon ($0.37 per liter). Based on a project life of 25 years and a contingency rate of 25%, the expected after-tax internal rate of return (IRR) for the community heating portion of the project is 29.6%. Total installed costs for the 1,195,000 Btu/h (350 kWthermal) community heating system, including distribution piping and its installation and backup oil systems, are estimated to be $631,000. For the lumber dry kiln, in the second heat-generating system, economic results were less favorable, with expected energy savings of $82,900 per year and an after-tax IRR of 24.1% (also assuming 25% contingency). Estimated installed cost of the 1,536,000 Btu/h (450 kWthermal) dry kiln system with a backup oil system is $513,800.
