LiPRO HKW wood gas CHP

The LiPRO HKW Wood-Gasification-CHP-Plant is an innovative renewable energy conversion facility, which converts solid biofuel by the LiPRO staged gasification process through a thermo-chemical reaction into a combustible syngas. This generated syngas will be converted by a combustion engine into thermal and mechanical energy. The thermal energy will be used for local district heating purposes, the mechanical energy will be converted by an electric generator into electric power in the same step and same technical unit.

LiPRO Wood-Gasification-CHP-Plant utilizes a unique multi-stage gasification process!

The innovative LiPRO Wood-Gasification-CHP-Plant is a wood gasification plant with a multi-stage gasification process. The LiPRO gasification unit has individual technical separated process stages in order to control individually but fully automated the single process-specific conditions of individual reactions. This ensures the production of most clean and tar free syngas and due to that, the most reliable plant performance.

Innovative Advantages:

    • After Pyrolysis, the long chained carbon hydrogen molecules get partly oxidised in the Oxidation to avoid tar in the syngas. Under the absence of solid fraction, while the charcoal goes straight into the Reduction unit, we are able to guarantee a homogeneous combustion on high and equal temperatures around 1050 °C. This ensures continuous production of high quality clean syngas, which can be used in combustion engines without complicated purification.
    • Further advantages consist in the separated Reduction and its geometry. This allows consistent lower temperatures to avoid glass ash formations
  • The innovative grate geometry allows an easy discharge of foreign materials such as stones or nails.

The nominal output of the Modell HKW 30 is 70 KW thermal and 30 kW electric and for the Modell HKW 50 110 KW thermal and 50 KW electric. It has an energy efficiency of 84 percent, based on the fuel consumption. By scaling up several plants in a row, the plant can be customized according to customers need.

The system can be operated fully automated without staff. For LiPRO wood power plant, only a 14-day maintenance and a weekly feed of the fuel storage is necessary.
