Belzona® Protects Exhaust Fan From Erosion

 
 

Industry:

Marine (MRNE)

 
 

Application:

Fans, Blowers and Compressors (FBC)

 
 

Customer Location:

BC, Canada

 
 

Application Date:

May 2010

 
 

Application Situation:

Exhaust fan

 
 

Problem:

The fan moves hot, moist, particulate laden exhaust air from the dryers. The hot air erodes the replaceable hardened steel blade faces while the swirling mixture erodes the back faces of the fan blades, compromising its structural and strength.

 
 

Products:

Belzona 1391 (Ceramic HT)

Belzona 1811 (Ceramic Carbide)

 

Substrate:

Mild Steel

 
 

Application Method:

The application was carried out in accordance with Belzona Know-How System Leaflet FBC-1 and FBC-2.

 
 

Belzona Facts:

Using Belzona 1811 to fare in and smooth the blade back help to reduce the swirl effect and protect the blade. On the blade faces, Belzona 1391 acts as a sacrificial coating and has proven to almost double the service life of the AR plate. It is planned to reapply Belzona 1391, when necessary, in situ to extend the service life even further.
