PROBLEM TO BE SOLVED: To reduce contaminant in extraction air in a turbomachine.SOLUTION: A turbomachine passage cleaning system includes a first airflow passage having a first inlet configured and disposed to fluidly connect to a compressor portion, a first outlet configured and disposed to fluidly connect to a turbine portion, and a first intermediate portion. A second airflow passage is fluidly coupled to the first airflow passage. The second airflow passage has a second intermediate portion having a second strainer. A first valve is arranged in the first intermediate portion upstream from a first strainer, and a second valve is arranged in the second intermediate portion upstream from the second strainer. The first and second valves are selectively operated to control fluid flow into respective ones of the first and second airflow passages to filter air passing from a turbomachine compressor portion to a turbomachine turbine portion. |
