Inefficient power generators replaced with proven wood gasifiers from Spanner Re²

As part of the repowering project, the originally installed wood gas generator from an external company was replaced by three wood gasifiers from Spanner Re² GmbH. Each with an electrical output of 45 kW, and extended by an efficient conveying and discharge system from Re². The ignition-jet CHP unit with an output of around 250 kW remained in place. 


Repowering of a large CHP plant based on wood gas

Data on the repowering project in Germany:

  • Local heating network operators with good access to wood fuel
  • Starting position: a wood gasifier and CHP unit from external company from 2009-2016 was in use
  • Problem: existing plant did not work, no smooth operation possible
  • 2016: replacement of the existing carburetor with 3 x Re² wood gasifier, integration of a new control unit as well as conveying and discharge technology


Successful repowering reliably supplies energy from wood chips

A superordinate, intelligent control system from Re² acts as a communication interface between the new wood gasification unit, conveying and discharge technology and existing CHP units. Thanks to the successful repowering project, a reliable energy supply can now be guaranteed. The heat generated from wood is transferred to the consumers via a local heating network. The wood chips are processed by the operator come from their own forest. With this innovative energy solution, the operator is able to optimise its added value and generate a lucrative source of income.
