Abstract

A turbomachine passage cleaning system (27) includes a first airflow passage (30) having a first inlet (32) configured and disposed to fluidly connect to a compressor portion (4), a first outlet (33) configured and disposed to fluidly connect to a turbine portion (6), and a first intermediate portion (34) including a first strainer (36). A second airflow passage (40) is fluidly coupled to the first airflow passage (30). The second airflow passage (40) has a second intermediate portion (44) having second strainer (46). A first valve (38) is arranged in the first intermediate portion (34) upstream from the first strainer (36), and a second valve (48) is arranged in the second intermediate portion (44) upstream from the second strainer (46). The first and second valves (38,48) are selectively operated to control fluid flow into respective ones of the first and second airflow passages (30,40) to filter air passing from a turbomachine compressor portion (4) to a turbomachine turbine portion (6). Corresponding turbomachine and method of filtering an airflow are also provided.
