Air-drying timber stack. Wood drying (also seasoning lumber or wood seasoning) reduces the moisture content of wood before its use. When the drying is done in a kiln, the product is known as kiln-dried timber or lumber, whereas air drying is the more traditional method. There are two main reasons for drying wood: Woodworking
Drying malted barley for brewing and other fermentations; Drying hops for brewing (known as a hop kiln or oast house) Drying corn (grain) before grinding or storage, sometimes called a corn kiln, corn drying kiln [8] Drying green lumber so it can be used immediately; Drying wood for use as firewood; Heating wood to the point of pyrolysis to ...
The moisture content of firewood determines how it burns and how much heat is released. Unseasoned (green) wood moisture content varies by the species; green wood may weigh 70 to 100 percent more than seasoned wood due to water content. Typically, seasoned (dry) wood has 20% or less moisture content.
If wood is heated away from air, first the moisture is driven off. Until this is complete, the wood temperature remains at about 100–110 °C. When the wood is dry its temperature rises, and at about 270 °C, it begins to spontaneously decompose. This is the well known exothermic reaction which takes place in charcoal burning. At this stage ...
The Thermo wood process consists of drying, heat treatment and finally cooling/conditioning, and takes up to 72 hours. [4] The Plato process consists of hydrothermolysis, dry curing and conditioning, and can take up to 7 days. The required time depends on wood species, width and initial moisture content. [5]
Dry distillation, as in the original production of sulfuric acid from sulfates. Destructive distillation, as in the manufacture of charcoal, coke and activated carbon. Charcoal burning, the production of charcoal. Tar production by destructive distillation of wood in tar kilns. Caramelization of sugars.
World premiering in the Berlinale’s Forum, “Dry Ground Burning” marks the second feature collaboration between directors Joana Pimenta and Adirley Queirós, after Pimenta DP-ed Queirós ...
Today, burning of wood is the largest use of energy derived from a solid fuel biomass. Wood fuel can be used for cooking and heating, and occasionally for fueling steam engines and steam turbines that generate electricity. Wood may be used indoors in a furnace, stove, or fireplace, or outdoors in furnace, campfire, or bonfire.
