Plant Technology

The typical wood chip plant is constructed around a solid fuel boiler with step grate or travelling grate. The boiler has refractory linings round the walls of
the chamber in order to ensure the combustion temperature despite the relatively wet fuel.
The plant designs are highly automated so that e.g. the feeding system of wood chips from the storage onto the grate is carried out by means of a computer
controlled crane that simultaneously keeps track of the storage.All the systems have the same main components:

• Wood chip storage
• Crane or other chip handling
• Feeding system
• Combustion chamber and boiler
• Flue gas purifying
• Flue gas condensation
• Chimney
• Handling of ash
