• Intuitive boiler control on SPC basis with very high transparency of operating data
  • High level of efficiency due to three-pass technology, an integrated economizer and effective heat insulation materials
  • High level of pressure consistency and steam quality even with widely fluctuating steam demand
  • The boiler can be equipped with a separate fourth pass for waste heat use
  • The boiler body can also be used as a pure waste heat boiler behind combined heat and power plants or gas turbines
  • Automatic start-up, standby and shutdown control SUC
  • Suitable for all burner systems
  • Pollutant reduced combustion thanks to the use of highly developed firing systems and careful matching of the best boiler and burner combination
  • Simple commissioning due to pre parameterised boiler control
  • Easy wiring on site thanks to plug-in connections

Additional details

Thought out to the final detail

The flame tube, the internal wet-back rear smoke gas reversing chamber, as well as the first smoke tube and second smoke tube, are all arranged for optimum flow within the horizontal cylindrical pressure vessel. Radiant and convection heat surfaces generate in tandem a rapid water circulation, which accelerates the steam bubble transport to the steam chamber. The transferred fuel heat is converted into steam quickly and without material stress through an even heat transfer. The large water chamber offers sufficient storage volume to be able to cover off even sudden peaks in consumption.

Optimized efficiency

The flue gas flow from the steam boiler contains significant heat potential. For an increased boiler efficiency this series of boiler is also available with an integrated economizer for flue gas heat recovery.

In addition the optional modules for continuous feed water control, speedcontrolled burner fan and O2 or CO control should also be used to give an even more efficient and environmentally friendly operation.
