Abstract:
1. An air cooled component for use in a combustion turbine engine, the air cooled component comprising: a cooling air inlet wherein a volume of cooling air enters the air cooled component; a centrifugal particle separator that receives and separates the volume of cooling air into a filtered portion and an unfiltered portion, the centrifugal particle separator being arranged within the air cooled component and proximate the cooling air inlet, comprising; a cooling air network arranged within the air cooled component and receiving the filtered portion of the volume of cooling air, the cooling air network comprising a plurality of flow channels having a cross sectional size reduced by an amount proportional to the minimum particle size removed from the filtered portion of the volume of cooling air; and an air outlet in communication with the conical portion that receives the unfiltered portion of the volume of cooling air and exhausts the unfiltered portion from the cooled component to the flow-path.
