Abstract
A fuel nozzle with turning guide is included in a gas turbine. The turning guide is disposed in an air inlet of the fuel nozzle to distribute a flow of compressed air and includes at least one of a turning separator, an inner separator, and an outer separator. The fuel nozzle includes a central body having an outer wall; a shroud concentrically disposed with respect to the central body and configured to surround the central body while maintaining a space for an air passage between an inner wall of the shroud and the outer wall of the central body; a rim formed on one end of the shroud and forming an air inlet communicating with the air passage; and a turning guide including a turning separator disposed in the air inlet, to make the air flow uniform, thereby suppressing the creation of an air pocket.
