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.
