Abstract
Systems and methods are provided for cleaning one or more cooling passages associated with a combustion chamber of a gas turbine engine. The gas turbine engine has a compressor section upstream from the combustion chamber. In one embodiment, a method includes: receiving a pressurized fluid from a source; directing the pressurized fluid through an inlet of a chamber such that a portion of a plurality of particles within the chamber is entrained within the pressurized fluid; and injecting the pressurized fluid with the entrained portion of the plurality of particles downstream from the compressor section through an end wall of a diffuser and deswirl system of the gas turbine engine or through a plenum upstream from the combustion chamber to clean the one or more cooling passages associated with the combustion chamber.
