Operation of Wood-Fired Boilers

The design of our boilers uses the "8-point" operating principle:

Wood Fuel

  • fuel storage unit (silo)
  • fuel transferred to the boiler


  • fuel loaded into the foyer
  • combustion
  • heat exchanger

Waste Treatment

  • smoke treatment
  • ash collection


  • automated systems / control system / control room
