NCSD® Operation Principle

Specially designed for cleaning of high temperature areas, up to 1500°C flue gas temperatures Nirafon Cleaning Sound Device is an effective non-invasive method for cleaning of the high temperature areas of the boiler plants. The method enables the on-line cleaning of both the furnace area and the superheater through acoustic energy generated by burning a small amount of gas inside the combustion chamber of the Nirafon Cleaning Sound Device (NCSD®) and by guiding the resulting sound pressure pulse over 170dB through a horn into the space to be cleaned.

The Acoustic Cleaning effect of the NCSD is obtained by quickly burning a small amount of flamable gas in the combustion chamber of the device and leading an acoustic pressure pulse through a horn into the space to be cleaned. LP or Natural gas is used to fuel the device, obtainable e.g. out of the LP gas network for the ignition burner.

The NCSD® cleaner produces 4 to 10 cleaning pulses per second and the cleaning will is operated for a few seconds with a few minute intervals. The particles soiling the surface stick to eaach other as well as adhering to the surface of the structures. The change in the speed of the gas flow brought about by the NCSD® detaches the particles as the force it exerts on the particle is greater than the adhesive forece retaining it. Once the particles have been detached by the pulses of the cleaner quickly following each other, they either fall down by gravity or continue their passage in the flue, propelled by the stream of flue gases.

Principle Advantages

The new NCSD® enables acoustic cleaning of the entire boiler plant. When the new NCSD® cleaner is used at temperatures exceeding 1000° C and traditional pneumatic Nirafon® acoustic cleaning areas of lower temperatures, the advantages of acoustic cleaning is achieved in the entire plant.

  • Cleaning during process
  • Heat transfers and other surfaces to be cleaned stay permanently clean and the process can continue without interruptions, rendering expensive shutdowns unnecessary
  • Also cleans the shadow areas and around the corners.
  • Acoustic cleaning reduces the use of water drastically in plant
  • Does not cause any harm to structures
  • No mechanical wear, corrosion or erosion
  • Acoustic Cleaners require little space,
  • Maintainence and operating cost are low
  • The refund time of the system is short
  • A tailor made plan is always drawn up by Nirafon Oy according to the buyer’s need and application.
