Boilers, Economisers and Air Preheaters

Nirafon 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 apace 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 (800⁰C -1400⁰C) of boilers such as the superheaters, waterwalls etc.

Bag Filters

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 clear, 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 waif 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 participate 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
