2. KILN CASSETES SHEETING AND INSULATION SYSTEM

The heat insulation system is made of aluminum cassette-panels of alloy with high density non-flammable rock wool thermal insulation of 120mm thickness, the density of rock wool is 55kg/m3, which is higher than that of fiberglass. There is a slope on the roof, avoiding accumulation of rain or snow on the roof. The kiln wall is externally and internally faced with corrugate embossed aluminum sheets with a granulated finish of 1.1 mm. The Cassettes themselves are specially mounted with the supported of aluminum plate between columns of bearing structure. High-temperature caulking between cassettes protects the walls from heat transfer. The caulking is applied at any cassettes joints.

The thermal constant of the jacket penetrability is k=0.45w/m-2.k-1. This is due to the particular construction characteristics of the walls. They are completely fire resistant; they do not absorb moisture, guaranteeing constant operation.

What Is Kiln Drying? The Reasoning Behind Drying Wood

Lumber Mill Kiln

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The Kiln Drying Process

Lumber and LogsWhen trees are felled and brought to a lumber mill, the first step is usually to debark and sort the logs by species, size or by end use. Logs destined for wood flooring, for example, are then sawn into rough boards of the required dimensions. These are often edged or trimmed for length before they are dried.

Drying can be done either by air or by kilns, which use circulating heated air to more rapidly remove the excess moisture from the wood. Each charge (or kiln load) is sorted by species and dimensions to optimize the process and to ensure that the final moisture content levels are even across the charge. After the wood has reached the correct moisture level for that species, it is sent through the planer and planed to its final dimensions, sorted to grade and shipped out. For wood flooring or other specific end products, the wood is typically shipped to a manufacturer for further planing, processing, and finishing. Mills and manufacturers alike invest time, money and training into their drying processes to provide optimal grade products at the correct moisture levels for their customers.

So if the wood leaves the kiln at the required moisture content level, the moisture content process is complete, right? It might seem feasible, but in reality, kiln drying is only the first step of a wood product’s life-long interaction with moisture. Kiln drying significantly reduces the moisture content of green lumber, but there’s more to be considered.

Moisture Past the Kiln

The reality of wood’s nature, and indeed, part of its attraction over the centuries, is that it is a hygroscopic material. Until it is fully sealed, wood constantly interacts with moisture in its environment and will absorb or release moisture as necessary to find a balance with its environment.

Examined closely, wood’s long, hollow cell structure means that each board is composed of bundles of long cells (think of a stack of drinking straws). In a living tree, those pathways function to move moisture and nutrients from the roots to the branches and leaves of the tree. Once the tree is felled, those pathways begin to lose that moisture as the wood dries. That moisture is naturally not replaced as it would be in a living tree, and the wood’s moisture level will drop considerably as it dries. The kiln drying process helps to draw that moisture out while minimizing the damage to the wood that rapid changes might cause.

Why is that so important?

“Wet” or green wood does not function well for anything from campfires to building materials. Its performance as green lumber can be unpredictable because of that inevitable moisture loss after the living tree is felled. As it dries, wood can twist, crack, warp, and shrink in its physical dimensions, making it less than ideal for buildings, flooring or woodworking. It’s an ongoing cycle in wood.

Think of a sponge. When a sponge is wet, it holds moisture in each hole or cell. As it dries, it not only releases that moisture, it shrinks in size. If it has been trimmed to a functional shape, like a rectangle, it may twist or curl as it dries. It does not, though, lose its capacity to reabsorb water when it is present. The sponge’s physical dimensions will change each time it absorbs and releases moisture.

In the same way, wood may have much of its moisture removed during the kiln drying process, but it does not lose the ability to reabsorb moisture that is in its environment. It might be a direct water source, moisture in an adjacent material or even humidity in the air; wood’s cellular structure will be ready to absorb any moisture it contacts.

 

FAQ:
