Biomass power plant HKA 70

More power, lower fuel consumption and new intelligent control software: the innovative biomass power plant "HKA 70" is the first representative of the new generation of biomass power plants from Spanner Re².

With a turbocharged gas engine, increased heat utilization and a special cooling process, the tried and tested wood gasification technology has been further developed in a highly efficient manner. The HKA 70 is equipped with a synchronous generator as standard, so that the system is started by means of wood gas and no longer powered. This saves costs and ensures safe plant operation even with less stable power grids.

The innovative Re² control system controls the entire plant operation and optimizes runtime stability. The menu structure is reduced to the essentials, which increases operating comfort and makes the control system particularly user-friendly. In addition, the HKA 70 only has one common control cabinet for wood gasifiers and wood gas CHP units. The output of the innovative biomass power plant is around 68 kWel and 144 kWth.

Due to its modular design, the HKA 70 - like the "smaller" wood-fired power plants from Re² - can be combined to increase performance and several biomass power plants can be cascaded.

Large-scale biomass power plant HKA 70 – in the overview:

  • Higher filter surface area, therefore longer service life
  • Electrical efficiency increase of the wood gas CHP
  • Increased heat recovery by reducing exhaust gas temperatures
  • Second cooling circuit for mixture cooling integrated
  • Powerful turbocharged gas engine
  • Single ignition
  • Standard built-in synchronous generator
  • Low inrush currents due to wood gas start
  • A control cabinet for wood gasifier and wood gas CHP with new software and improved operability

Who benefits most from the wood gasifier HKA 70?

  • Forestry and agricultural
  • Woodworking and processing companies such as joinery, carpentry or sawmills
  • Heating plants
  • Hotels with wellness areas
  • Local heating networks
  • Industrial plants
