Wood Chips or Chips: Know the Most Used Types

wood chips
Chips, also known as chips, are small pieces of wood made up of shredded chips and obtained from trees such as eucalyptus, pine and black wattle. Because it is the use of leftover organic matter, wood chips are a type of biomass important for energy production for furnaces and boilers. Thus, this renewable resource has been recognized as the most suitable fuel to generate energy in the industrial sector - which relies on specific mechanical screw and silo systems. In addition to direct shredding, after cutting down trees reserved for the timber and reforestation markets, it is possible to find chips in the residues of industries and sawmills. Another common way to obtain chips is through the process of chipping wood that has already been discarded and can be recycled. Each way of obtaining wood chips has a specific purpose, since the tree portions vary, meeting different demands of the companies. To obtain wood chip quality, we need to observe the types of cut and the amount of inputs. Furthermore, it is essential to understand that the energy capacity of a forest fuel is linked to its calorific value, which in turn depends on its chemical composition and humidity. Get to know the main types of chips used in the world and their advantages:

1 type: Forest Sediment Chips

1 chips result from shredding parts of the tree - branches, leaves, bark and crowns - and even whole trees. Since the 1 chip contains more varied portions of the tree, the moisture caused by the joining of residues - which may reach 50% - affects the value of the material. Due to the reduced commercial value, the product is ideal for feeding large central boilers, which demand a large amount of chips in the power generation.

Type 2: Sawmill Chips

Already type 2 consists of smaller pieces of wood, derived from waste from sawmills. Because it is made of smaller pieces, the material has a more efficient combustiondue to increased contact area. However, as the 2 type contains between 40 and 50% moisture, a drying and grinding process is required to further benefit.

Type 3: Chips from the Straight Cut

Last but not least, the 3 chip comes from branchless and leafless logs. In addition, the material goes through a long drying process, which lasts between 4 and 6 months. Thus it is possible to reduce the humidity to 30% as well as to ensure a more uniform material.

Advantages of using Wood Chips:

Two advantages for the market are the low cost the acquisition of the raw material, as well as the best performance of the product, when it comes to silos flow. Another notable advantage is the reduction of environmental impacts, as wood chips are a renewable resource and which has carbon neutral. That is, the emission of carbon dioxide generated by burning the material is equivalent to the amount of carbon dioxide that the product, as a tree, has already removed from the atmosphere. In addition, the ashes from burning them are less environmentally aggressive than those from fossil fuels.
