Diagnostics Test – cold air velocity test (CAVT)

A Cold Air Velocity Test (CAVT) in a boiler is a method used to predict flue gas flow patterns, identify areas of high velocity, and assess potential erosion risks, especially in the second pass of the boiler. 

Benefits

      • Identifies areas prone to fly ash erosion, a leading cause of boiler tube failure. 
      • Helps to optimize boiler design and operation to minimize erosion risks. 
      • Allows for the installation of diffusion and distribution screens to address high-velocity zones.
