Waste Heat Boiler – AHK-ip

The SCHNEIDER waste heat boiler, type AHK-ip is also a flue tube boiler but it is designed with special surface-structured heat transfer tubes (ip-tube). The structuring of the pipe surface leads to two essential benefits for this type of boiler over the smooth tube boiler.

• Greatly improved heat transfers by increasing flow velocities as a result of turbulence caused by the cross-sectional changes. The resulting savings in heating surface ultimately lead to a significantly more compact and thus space-saving boiler design.
• Reduction of the heating surface contamination with existing particle-laden flue gas flows. This benefit also results from the aforementioned effect of increased flow turbulence.

Benefits of the AHK-ip in addition to type AHK:

• Compact design
• Reduction of heating surface contamination
• Increase in travel times (interval between two cleanings)
• Further increase in overall system efficiency
• Further minimisation of operating costs
