GAS TURBINE OFFLINE COMPRESSOR WASH WITH BUFFER AIR FROM COMBUSTOR

摘要

A system and method for washing a gas turbine engine. The method for washing the gas turbine engine includes coupling a pressurized air supply assembly to an air supply and to a secondary air system, cranking a compressor rotor assembly of the gas turbine engine, supplying pressurized offline buffer air from the air supply to the pressurized air supply assembly, and spraying a cleaner into the compressor.

主权项

1. A pressurized air supply assembly for a gas turbine engine, the gas turbine having combustor with an injector port and a secondary air system, the pressurized air supply assembly comprising:
an air conduit having a first end and a second end; a secondary air system pneumatic couple coupled to the first end of the air conduit, the secondary air system pneumatic couple including an adapter configured to attach to a part of the secondary air system; and a local air supply adapter including a conduit mount and an injector port flange, the conduit mount coupled to the second end of the air conduit, the injector port flange configured to fit and attach to the injector port, the injector port flange forming a cap over the injector port with at least one air passageway passing through the cap and terminating at the conduit mount.
