High quality and flexible
ETA wood chip boiler
HACK VR 250 to 500 kW
In times of rising raw material costs, it is a real challenge to heat larger properties – not, however, if you rely on a crisis-proof and domestic fuel, such as wood chips. Wood chips are produced from wood that is otherwise difficult to reuse, such as thinning materials, splinters of wood after storm damage and sawing residue from domestic wood processing plants. It is chopped in powerful chippers and according to predefined standards. The size of wood chips is standardised. Sizes from P16S - P31S are suitable for our systems.
A system that can handle coarse chips too
Every ETA wood chip conveyor system is well thought out, tried, tested and designed for the toughest use: the transport of coarse, uneven wood chips. So that pieces of wood of up to 12 cm can be transported, all parts must work together perfectly. That starts already in the bunker. The wood chips reach the screw via generously designed open troughs. In the process, a relief plate prevents the material from exerting too much pressure on the discharge screw and thus enables fill heights of up to five metres. Bottlenecks are avoided in the enclosed trough channel thanks to the spacious discharge connections. A smooth material transport is supported by the progressive screw, which additionally loosens the wood chips. Even the installation is easy thanks to the modular design. The screw modules with sizes of 25 to 200 cm are produced and aligned in automated machines, the specially shaped trough channels only have to be screwed together.
