Unique biomass handling and processing capabilities

Bruks Siwertell is the market leader in the biomass handling sector. Siwertell ship unloaders have the unique ability to handle biomass safely in a totally-enclosed system and our loading, conveying, stacking and reclaiming, truck unloading, chipping, milling, screening and wood-residue processing systems support every part of the of the bioenergy logistics chain, from the forest to the pellet.

Environmental regulations drive biomass boom

The increasing trade in biomass results from coal-fired power plants burning biomass to achieve carbon-neutral operations that comply with environmental protection regulations. Many plants are adapting to burn both fuels. Separate power-generation systems can be found on the same site: one burning coal, one burning biomass. In others, a single system burns either coal or biomass, or both at the same time, known as co-firing. In all cases these plants benefit from the flexibility of Siwertell unloaders as they can handle both commodities in one machine, without adjustment.

Unrivalled biomass-handling experience

Decades of technological developments in the transfer, transport and processing of wood for the biofuel market through to the pulp and paper and particle board industries, gives Bruks Siwertell unrivalled knowledge of biomass-based materials.

We pass this experience onto our customers in the form of market-leading machinery and through-life services, which deliver excellent levels of operational performance, safety, efficiency and environmental protection.

Flexibility, capacity and safety requirements

Biomass producers and consumers are often on different continents, requiring efficient marine transportation, wood-processing and handling. Biomass in bulk has a lower calorific value than the same volume of coal, so high-capacity systems are needed.

With the potential for fire and explosion, especially when contained, biomass-handling systems must be able to mitigate these risks. In addition to this, they must also ensure minimal cargo degradation, not simply to preserve the quality of the shipment, but by minimizing dust creation low, fire and explosion risks are reduced.

Bruks Siwertell benefits from decades of sulfur-handling experience. This has been used to develop safety systems for biomass handling, meeting CE conformity regulations and the latest ATEX directive relating to the control of explosive atmospheres. Consequently, Bruks Siwertell offers the only totally-enclosed Siwertell ship unloaders that can safely be used for large-scale biomass handling.

Ship loaders and conveying systems also benefit from our long experience of handling hazardous cargoes.

Systems that offer broader benefits

A ship unloader that can handle coal and biomass efficiently reduces investment costs and provides the flexibility needed for changing market conditions. High through-ship unloading capacity means that jetty occupancy is minimized, while annual intake is maximized.

All Siwertell ship unloaders, for biomass and other bulk materials, have small structural footprints and weigh less than alternative systems with comparable capacities. This results in reduced jetty construction or conversion costs.

Our loading, stacking and reclaiming, and conveying systems further add to the overall efficiency of a biomass-handling operation. Ideally suited to conveying this commodity is our innovative air-supported conveyor range, which includes the Bruks Tubulator and The Belt Conveyor.
