Available in PDF, EPUB and Kindle. Book excerpt: Academic Paper from the year 2015 in the subject Engineering - Chemical Engineering, , language: English, abstract: This research aims to design and fabricate a solar kiln dryer that uses a solar panel to trap the sun’s rich energy and also the design of an inverter that converts the direct current of the sun to an alternative current that will charge the battery and power heater element for drying. The principal mode of heat transfer is convection. The temperature of the incoming stream of air is raised by the heating element, a circular motion fan drives the heated air uniformly through the heating chamber, in this way heat is convectively transferred from the hot air to the cold air. Wood is a hygroscopic material which gains moisture content as a result of changes in humidity. Hygroscopicity is one of the most distinctive properties of wood. Any kind of wood product absorbs and desorbs moisture from the surrounding air until it reaches equilibrium moisture content (EMC), a balance point between the wood’s moisture content and that of the surrounding environment. Fresh cut lumber contains a great deal of water. If the water is not removed, the lumber can’t be used to produce a high quality finished product. Properly dried lumber sells for a higher price and is much easier to work with than lumber that have not been dried. When lumber is well dried it machines better, glues better, and finishes better. Drying also improves the strength of the lumber, kills infestations, hardens pitch, preserves colour, reduces weight and controls shrinkage. Lumber that is not dried under controlled conditions is prone to warping, staining, and other degradations that diminishes its selling price and workability.

Download or read book Design and Operation of a Solar heated Dry Kiln for Tropical Latitudes written by Brian H. Bond and published by . This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lumber is usually dried to a specific moisture content prior to further manufacturing or use. While lumber can be air-dried, the ambient humidity in most localities prevents the lumber from reaching the moisture content necessary for dimensional stability and use, especially for interior use. Solar kilns are an inexpensive alternative to conventional steam-heated kilns, especially for small operations and communities. Solar-heated kilns have great potential in developing countries, especially in remote locations with little access to conventional energy sources. This publication describes the construction and operation of a solar kiln for lumber drying in tropical latitudes.

Book excerpt: Drying Hardwood Lumber focuses on common methods for drying lumber of different thickness, with minimal drying defects, for high quality applications. This manual also includes predrying treatments that, when part of an overall quality-oriented drying system, reduce defects and improve drying quality, especially of oak lumber. Special attention is given to drying white wood, such as hard maple and ash, without sticker shadow or other discoloration. Several special drying methods, such as solar drying, are described, and proper techniques for storing dried lumber are discussed. Suggestions are provided for ways to economize on drying costs by reducing drying time and energy demands when feasible. Each chapter is accompanied by a list of references. Some references are cited in the chapter; others are listed as additional sources of information.

This book was released on 2013-08-27 with total page 619 pages. Available in PDF, EPUB and Kindle. Book excerpt: For courses in Civil Engineering Materials, Construction Materials, and Construction Methods and Materials offered in Civil, Environmental, or Construction engineering departments. This introduction gives students a basic understanding of the material selection process and the behavior of materials — a fundamental requirement for all civil and construction engineers performing design, construction, and maintenance. The authors cover the various materials used by civil and construction engineers in one useful reference, limiting the vast amount of information available to the introductory level, concentrating on current practices, and extracting information that is relevant to the general education of civil and construction engineers. A large number of experiments, figures, sample problems, test methods, and homework problems gives students opportunity for practice and review.
