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.
Resin-bound systems incorporating 6-10mm dried aggregates and larger sizes are generally used as tree surrounds known as tree pits. These are a cost-effective and practical alternative to metal tree grilles that are stolen for scrap value, are costly to purchase and harbour litter thus increasing maintenance costs for local authorities and tax ...
CLS timber is kiln-dried and is white wood. [9] Tree sources include Fir, Pine and Spruce. [10] [6] CLS is planed and fished with eased or rounded edges. [9] [11] CLS timber is commonly graded at two strengths, C16 or C24. [9] C24 is the stronger and is typically more expensive. [10]
Roller kiln: A special type of kiln, common in tableware and tile manufacture, is the roller-hearth kiln, in which wares placed on bats are carried through the kiln on rollers. In the intermittent kiln, the ware is placed inside the kiln, the kiln is closed, and the internal temperature is increased according to a schedule. After the firing is ...
This pottery is handmade, and potters dig clay locally to produce their wares. Tempering agents like sand, volcanic ash, or pieces of ground-up broken pottery are combined with the clay to harden it during the firing process. The vessels are then pit-fired in the ground. Wood, dung, coal, or other locally sourced materials are used as fuel. [7] [8]
Materials such as stones, sand and ceramics are considered 'dry' and have much lower equilibrium moisture content than organic material like wood and leather. [7] typically a fraction of a percent by weight when in equilibrium of air of Relative humidity 10% to 90%. This affects the rate that buildings need to dry out after construction ...
The process of kiln or oven drying firewood was invented by Anthony Cutara, for which a successful US patent was filed in 1983. [22] In 1987 the US Department of Agriculture replicated the method and published a detailed procedure for the production of kiln dried firewood, citing the higher heat output and increased combustion efficiency as a ...
The Hoffmann kiln is a series of batch process kilns. Hoffmann kilns are the most common kiln used in production of bricks and some other ceramic products. Patented by German Friedrich Hoffmann for brickmaking in 1858, it was later used for lime -burning, and was known as the Hoffmann continuous kiln .
