Water Tube Boiler – iNook

The iNook is a drumless vertical boiler featuring a membrane wall construction specially developed for closed steam cycles. It is operated in a closed natural circulation system and is directly connected to the heat consumer in such a way that it cannot be unlocked. The steam produced serves only as a heat transfer medium, which transfers the energy contained in the steam to a secondary process via a heat exchanger (condenser).

Benefits of the iNook

• Membrane wall construction
  • 100% flue gas tightness between the channels – no exchange
  • Highest possible efficiency compared with other types
• Direct integration of the evaporator tubes in the collector (without reductions)
  • No risk of heating surface overheating / flow interruptions
• Number and arrangement of steam discharge pipes
  • Minimisation of pressure losses in the boiler system
  • Increase in the water circulation rate
