The nacelle anti-icing system includes a nose cowling assembly having a nose ring and an inlet duct connected to the nose ring, the nose ring including a plurality of openings formed therein; a nose cowling conduit positioned in the nose ring for communicating a heated gas to the plurality of openings formed in the nose ring and for creating a heated gas boundary layer on the inlet duct, and a mechanism connected to the nose cowling conduit for generating the heated gas. The method includes the steps of feeding a heated gas through the nose cowling conduit and through a plurality of openings formed in the nose ring and generating a heated gas boundary layer on the inlet duct so as to heat the inlet duct.
