Biomass Boiler

• 110 t/h steam capacity (83 MW), 16MWel, process heat and cooling water for adjacent industry
• Fuel: natural wood
• Dimensions ECO bundles:
  • W 6.5m x L 2.5m x H 1.5m -PT 76mm, PL 73mm, tube diameter 31.8mm
  • Finn geometry: 120mm x 70mm rectangular fin plates connecting two tubes
  • Distance between fins: 19mm
  • Manufacturer: Favier-Setrem
• Initial cleaning equipment: rake soot blower above each ECO bundle (10t/h steam consumption soot blowing 3x/day); 2 Nirafon sonic horns between bundles; manual online boiler cleaning every 14 days
• Since 07/2016: Shock Pulse Generators, 1x EG10XL, 1x TwinL; Shock Pulse Interval 1h
