Abstract
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.
Claims20
A method for washing a compressor in a gas turbine engine, the method comprising:
- coupling a pressurized air supply assembly to an air supply;
- coupling the pressurized air supply assembly to a buffer air path, the buffer air path leading to a first seal of at least one intermediate bearing assembly of the gas turbine engine;
- 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
- delivering cleaner to the compressor.
A method for washing a gas turbine engine, the gas turbine engine including a compressor and a combustor, the method comprising:
- shutting off fuel to the combustor;
- cranking the compressor of the gas turbine engine;
- distributing a cleaner into the compressor;
- and
- supplying compressed air to a first seal of an intermediate bearing assembly of the gas turbine engine via a secondary air system.
