Acoustic Cleaning Systems keep heat transfer surfaces clean
in boilers using a variety of fuels. The main advantages are
On-line cleaning with flexible operation time, low operation
and maintenance costs, low capital cost and space requirement,
no adverse effects on heating surfaces and structures. Nirafon
Acoustic Cleaning Systems are an effective replacement of steam
soot blowers in many applications. The Nirafon Gas Pulse Cleaners
provide effective acoustic cleaning for the high temperature
zones (800°C -1400°C) of boilers such as the superheaters,
waterwalls etc. |

 Nirafon
Acoustic Cleaning Systems serve as an effective supplement to
existing Pulse Jet and Reverse Air mechanisms for proper bag
cleaning. This gentle cleaning method reduces pressure drops,
prolongs bag life by minimising mechanical stress and strain
on them and also helps in reducing compressed air / inert gas
consumed by conventional cleaning methods. Acoustic cleaning
is also highly effective in solving flow problems in hoppers
and is the ideal cleaning method for Glass Bags. |

| Fans/
Blowers |
 Nirafon
Acoustic Cleaning Systems find effective use in industrial fans/blowers
having material deposition on impellers, leading to unbalance
and high vibration levels. Nirafon Acoustic Cleaning Systems
provide On-line uniform cleaning , restrict vibration levels
within acceptable limits thus prolonging bearing life, reduce
frequency of shutdown and down time for manual cleaning and
improve fan availability |
|
|
| Electrostatic
Precipitators |
 Nirafon
Acoustic Cleaning Systems are used for cleaning of Gas Distribution
Screens, Collecting Plates and Discharge Electrodes, supplementing
existing rapping systems. Nirafon Acoustic Cleaning Systems
ensure uniform gas flow and maintain consistency in ESP performance,
reduce frequency of mechanical rapping and thus minimise electrode
damage and misalignment. Use of Nirafon Acoustic Cleaning Systems
also eliminates hopper build up and field grounding problems |

|
| Heat
Exchangers and Forced Draft Coolers |
| Nirafon
Acoustic Cleaning Systems keep tube surfaces of heat exchangers
and Forced Draft Coolers clean, thus maintaining high levels
of heat transfer and reduced pressure drops. Nirafon Acoustic
Cleaning Systems reduce the need of cleaning shutdown and downtime
thus improving equipment availability. |
|
|
| Hoppers/
Bins/Silos |
 Nirafon
Acoustic Cleaning Systems provide an effective solution to material
flow problems such as Side wall Buildup, Ratholing and Bridging/Arching
in hoppers/bins/silos handling a variety of materials. Nirafon
Acoustic Cleaning Systems reduce the need for manual cleaning,
improve availability and eliminate structural damages due to
vibrators, manual hammering, poking etc. |
|
|
| Spray
Dryers and Cyclones |
| Nirafon
Acoustic Cleaning Systems find effective application in Spray
Dryers and Cyclones for dislodging / preventing material buildup
on vertical walls and conical portions, eliminating need of
manual cleaning thus improving equipment availability. |
|
|
| Ducts |
 Nirafon
Acoustic Cleaning Systems are used to eliminate / minimise dust
and particulate matter build up in ducts in a variety of industries.
Advantages are improved availability of the duct and reduced
need of shutdowns for manual cleaning. |
