The ideal solution for farmers (agricultural holdings) private estates and companies who have the possibility of using their own fuel source or having it delivered from a local supplier in the form of woodchips, saw dust, rape cake or other forms of bio fuel material.

Wood is an important energy source all over the world. In Denmark energy wood comes from wood chips, firewood and wood waste. Woodchips are made from cut up trees with an average length in the grain of 5-50 mm. In addition longer twigs and finer fractions in small percentages can be accepted. The use of wood chips for fuel is of great importance to the forestry industry, since the production and sale of woodchip allows for the necessary tending and thinning of the forest to be converted into a useful fuel

For heating plants wood is a convenient type of fuel. The moisture content in the wood chips varies from about 35 to 45%.

A typical wood chip system is built from the following components:

• fuel store
• fuel transportation system
• solid fuel boiler (typically a LIN-KA H-boiler)
• stoke system
• ash removal
• smoke cleaning
• Chimney

Wood chips / Sawdust systems for dry fuel (max. 35% water)
LIN-KA Maskinfabrik A/S have developed two main systems for handling and transporting wood chips in this kind of system. Both types of systems guarantee an efficient and complete combustion, which is fully automatically controlled via a PLC-control unit, which simultaneously monitors whether the system is constantly performing its best

The system consists of a hydraulic scraper arrangement (2-5 scraping arms) which pushes the wood chips or sawdust to a horizontal transportation auger, from here the wood chips are delivered into an inclined transportation auger. The stoke screw transports the wood chips onto a water-cooled hearth that is situated within the LIN-KA H-boiler, here an efficient combustion takes place. The scraper arrangement is established in a room next to the boiler room
