CO2 blasting For Your Next Outages

HRSG cleaning with dry ice c02Heat recovery steam generator (HRSG ) Cleaning aka HRSG cleaning with CO2 Blasting is the most requested process in power plants to increase efficiency and save costs. helps decrease back pressure while performing this process of cleaning . HRSG’s accumulate contaminants and deposits on their finned tubes. These tubes are used to conduct heat. Contamination then resists the transfer of heat through the fins, this causes a loss of efficiency. If the contamination accumulates even to a small amount, this can create lack of airflow, it may severely restrict the flow of gas across the tube banks, which is an important part of the process . HRSGs will eventually experience fouling caused by tube deposits and corrosion. This will eventually reduce steam production, decrease steam temperatures, and thus degrade combustion turbine (CT) and combined cycle performance. These cause the plant’s operating cost to increase in the form of increased fuel consumption and lost electricity sale revenue, and extended outage With the dry ice you blast the contaminant off and it never becomes wet and corrosive, which is the best answer to this need. Dry ice blasting is used in plants for cleaning the following:

  • Turbines
  • Compressors & Generators
  • AC/DC Motors
  • Circuit Breakers
  • Switch Gears
  • Transformers
  • Rotors, Stators
  • Insulators, Isolators
  • Bushings

Benefits includes::

  • Reducing catastrophic failure
  • Improving mega-Ohm readings
  • Increasing polarization indicator
  • Improving thermal dissipation
  • Reducing outage time
