Our wood power plants
All that the forest provides.
Our biomass power plant plants are so flexible as regards the raw material used that we can employ all forest residues, such as offcuts and sawmill by-products, for fuel. This unique diversity underlines the contrast to other technologies in the market, which use expensive wood pellets or perfect formed wood chips. This is made possible by the innovative stepped co-current fixed bed gasification technology, which allows maximum efficiency with maximum raw material flexibility. This leads to clear economic advantages for the operator.
- The fresh forest chip material is dried with heat generated within the wood power plant.
- Dry wood chips are thermochemically transformed into a gaseous fuel.
- In an engine with a generator, this gas is finally converted into electricity and heat.
Dry wood chips are first thermo-chemically transformed into a gaseous fuel in our plants, then converted into electricity and heat in a gas engine.

(1) ... expandable to an electric output of up to 250 kW
(2) … with optional upgrade for low-temperature usage; temperature is subject to seasonal fluctuations
(3) ... customer-specific adaptation possible
(4) … <W10 in front of the gas generator inlet; drying is ensured by adding the optional upgrade
As a general contractor, we cover on request also topics like drying, moving floor and the biomass feeding system for you.

2To use the resulting low-temperature heat, a heat pump can be offered optionally to reach a water temperature of up to 55°C. This temperature can be optimally used for biomass drying or to increase the backflow-temperature of the district heating system.
What they say about us
I have seen numerous different wood-gas systems. I finally decided on the product with the greatest potential in terms of the raw material used – the SynCraft wood-gas plant.
I have no idea how SynCraft manages it, but after several thousand hours of operation we can find no trace of deposits in our highly efficient gas engines.
The SynCraft biochar has convinced us regarding quality and price. This biochar ist especially used by our customers in the area of liquid manure stabilization, as litter for stables and as an additive for pet food due to healthy reasons.
In a wood power plant a firm, dry, biogenic fuel, as for example wood chips, is first converted into a gaseous fuel and then in an gas engine into electricity and heat by means of thermochemical processes.
The technology of SYNCRAFT® bases on a staged co-current fixed-bed gasifier but the actual gasification reactor is operated against gravity as beside diagram shows. Crucial in this unique setup is the separation of forces with in the fixed-bed. While in traditional fixed-bed reactors both forces are directed downward and thus increasing compaction over time is unavoidable, these two forces are opposite in a floating-fixed-bed reactor. With this small but subtle difference the charcoal bed in the gasifier is always perfectly loosened, no matter how fine or how structured the wood chips previously have been. In addition, stones and nails can be easily removed at the foot of the floating-fixed-bed reactor because of its upward operation.
Solid dry wood chips in a size classification of G30 - G50 but including fines and bark. In addition, it is tolerant against stones and nails within the fuel; for optimum operation, the fuel should contain as little impurities as possible.
The fuel must be for a water content in the range of W10 - W15 have; individual batches with a water content of about W30 or chunks of ice lead to a controlled shutdown of the plant.
Without storage and dryer about 10% of the electricity produced is consumed by the plant itself. The main power consumers are the gasification air blower, the air compressor, and the cooling water pump of the gas engine.
For optimum placement a CW 700 requires around 200m² and a CW 1000 around 275m² including a one-week dry wood chips storage. If necessary, the plants can also be realized with significantly less space available..
