Wood Chips and Pellets

In wood chips and pellets, we normally investigate the:

• Water content (as received and analysed moisture)
• Elementary analysis (carbon content, hydrogen content)
• Ash at 550°C
• Calorific value (as received and analysed moisture)
• Fuel value (as received and analysed moisture)
• Range of ash melting temperatures
• EOX content
• Micro-nutrients (toxic metals such as arsenic, cadmium, chromium, copper, mercury, lead, zinc, as well as sulphur, chlorine, nitrogen, sodium, potassium)
• Sieve analysis (size of the chip)

Wood Chips

Wood chips are wood pieces reduced in size by cutting devices. Shredded chips are, however, made by crushing wood with blunt, smashing tools.

Wood chips are primarily used as raw material for the wood-processing industry as well as biological and regenerative fuel. Depending on the source, bark or wood chips are also used.

Wood Pellets

Wood pellets are rod-like pellets used as fuel. They are completely or largely made of wood or sawing by-products.

The pellets have various advantages over other biological solid fuels such as the automated use as fuel in special pellet burners. Besides wood pellets, there are also larger briquettes made from wood shavings.
