Wood pellets are a compressed biomass fuel made from sawdust and other wood residues. These small, cylindrical pellets are a clean and efficient way to heat homes and businesses.

Materials and Production Process:

The primary raw material for wood pellets is sawdust, a byproduct of the woodworking industry. Other wood residues, such as wood shavings and bark, can also be used. The production process involves:

• Grinding: Wood residues are ground into a fine powder.
• Drying: The wood powder is dried to reduce moisture content.
• Compression: The dried powder is compressed into small, dense pellets under high pressure.
• Cooling: The pellets are cooled before packaging.

Shape and Size: Wood pellets are typically cylindrical in shape, with a diameter of about 6-8 mm and a length of 2-3 cm. However, the exact size can vary depending on the manufacturing process and intended use.

Specifications:

• Moisture Content: Low moisture content (typically less than 10%) ensures efficient burning.
• Ash Content: Low ash content indicates high-quality pellets.
• Density: High density results in a higher heat output.
• Binding Agents: Some manufacturers add natural binding agents like starch or lignin to improve pellet durability.

Benefits of Wood Pellets:

• Sustainability: Wood pellets are made from renewable resources and reduce reliance on fossil fuels.
• Efficiency: They have a high heat output and burn cleanly.
• Ease of Use: Wood pellets are easy to store and handle.
• Low Emissions: Wood pellet combustion produces lower greenhouse gas emissions compared to fossil fuels.

Applications:

• Heating: Wood pellets are commonly used in wood pellet stoves and boilers for residential and commercial heating.
• Electricity Generation: They can be used in power plants to generate electricity.
• Industrial Processes: Wood pellets can provide heat for various industrial processes.
