Gas Turbine Filtration


Filtration Method: Interception

Turbulant boundary layers of air around contaminant particles in the airstream generate the transfer of energy to create the inertial force moving the contaminant. Although contaminant particles are pushed in the airstreams general direction their paths are heavily affected by their inertia and mass. Interception is a form of inertial separation where the contaminant comes into contact with any point around the filter media due to an inertial change.

After contact is made, surface friction and static low pressure areas around the particle will prevent it from moving. This condition can affect all particle size, they can be disloged by other particles in the area stream but stopped particles can also help to catch moving particles.
