Abstract
A fuel-air mixer for a gas turbine engine combustor having a primary swirler and a venturi that effectively reduces carboning via purge air. Purge air flows axially through the fuel-air mixer forming a boundary layer of air on the inner surface of the venturi. The boundary layer of air minimizes the amount of fuel contacting the inner surface of the venturi resulting in reduced carbon resin or coke formation.
