Abstract
A method of cleaning gas turbine compressors using crushed, solid, sublimable material, such as dry ice, which can be used in during low temperature conditions, poses no risk of ice formation, clogging cooling hole passages, or degrading the emissions from the turbine.
Claims14
A method of cleaning a turbine compressor, comprising:
- providing at least one particle size of solid particles, said solid particles being capable of sublimation;
- injecting said solid particles into said turbine compressor through a port in said turbine compressor;
- and
- operating said gas turbine at a base load while performing said injecting.

A method of cleaning a turbine compressor, comprising
- providing at least one particle size of solid particles, said solid particles being capable of sublimation;
- and
- injecting said solid particles into said turbine compressor through a port in said turbine compressor,
- wherein said solid particles are injected just up stream of a bellmouth of said turbine compressor.
1 more element
A method of cleaning a turbine compressor, comprising
- providing at least one particle size of solid particles, said solid particles being capable of sublimation;
- and
- injecting said solid particles into said turbine compressor through a port in said turbine compressor,
- wherein said injecting further comprises developing a lower pressure inside said turbine compressor.
