PRODUCT : BOILER

The boilers are built under license Eckrohrkessel (ERK). More than 5000 boilers were built following this design which guarantees reliability and safe operation.

PRINCIPLE OF OPERATION

Due to the unique arrangement of mixture tubes, steam backflow tubes, overflow tubes and unheated downcomers and return tubes, a pre-separation of steam before the steam drum can be achieved. This results to excellent load change behaviour as well as a high steam purity.
This tube cage with all welded or separately supported heating surfaces is self-supported by downcomers in the corners of the boiler. A heavy supporting frame where other boilers systems have to be hung in is unnecessary. Hence, complicated connections between boiler and cold frame do not exist.
Eckrohr-Boilers are set up in the way that they can expand from the ground level to all directions.

PERFORMANCES

• Construction optimization
  • Pre-mounted boiler
  • That weld "simple" on-site
  • Competitive System v.s. firetube boiler
• Freestanding boiler
  • Rapid changes of capacity
  • Quick start
• Steam blowers
  • Rotating Head
  • Retractable System
• Evacuation of dry ash
  • Cost reduced due to lower evacuation tonnage than wet system and no water consumption
• Pre-separation
  • Good quality steam
  • If necessary, reduced superheating with condensed steam
• Specific design according to the biomass treated
  • 850 ° C / 2 s
  • Place for DeNOx, gas burner, additional DC
  • Limited velocity in the hearth to maximum 2 m / s (settling of ash)
  • Distance between tubes suitable
  • Limited temperature of the flue gas before the superheater (ash fouling and corrosion)
