Customer benefits

Good cleaning result by combined operation of Rapping System and SPGr16:

  • Frequency of rapping system was decreased, to reduce mechanical stress at the collectors
  • Significantly reduced number of  intermediate manual explosive cleanings
  • 1.5 years boiler operation period can be achieved, without necessity to reduce the load prior to the shutdown
  • More stable boiler operation conditions

Significant improvement by SPGr: stable operation during complete operating period

Improvements with SPGr16 operation (at all 3 lines):

  • Higher, more stable live steam production
  • Lower flue gas pressure drop over full operation period
  • No additional manual cleanings required
