Japanese Patent JP2017156033

A

PROBLEM TO BE SOLVED: To provide a combustion apparatus easy to keep a differential pressure before and after a fuel injection even when applying a fuel of a different property.SOLUTION: The combustion apparatus comprise a nozzle casing defining an axial flow passage, and a nozzle provided in the axial flow passage. The nozzle includes: a nozzle body of a cylindrical shape extending along the axial flow passage; a swirler vane configured to protrude radially outward from the nozzle body in the radial direction of the nozzle body and to cause a fluid flowing in the axial flow passage to swirl; at least one first injection hole opened in the surface of the nozzle body or the swirler vane; at least one second injection hole opened in the surface of the nozzle body or the swirler vane; a first fuel flow passage extending in the inside of the nozzle body and communicating with the at least one first injection hole; and a second fuel flow passage extending in the inside of the nozzle body separately from the first fuel flow passage and communicating with the at least one second injection hole.SELECTED DRAWING: Figure 6
