Abstract

The present application thus provides a wash system for use with a compressor having a bellmouth and one or more extraction pipes. The wash system may include a water source, a first fluid source, a mixing chamber in communication with the water source and the first fluid source, a bellmouth line in communication with the mixing chamber and the bellmouth, and a stage line in communication with one of the extraction pipes.

First claim

We claim:

1. A system comprising:
a turbine;
a compressor comprising a bellmouth, wherein the compressor comprises an air extraction system comprising one or more extraction pipes in communication with and extending between one or more extraction ports in the compressor and one or more stages of the turbine; and
a wash system configured to be attached to and in fluid communication with the air extraction system, the wash system comprising:
a water source comprising water;
a first fluid source comprising a first fluid;
a mixing chamber in communication with the water source and the first fluid source;
a water pump configured to pump the water to the mixing chamber;
a first fluid pump configured to pump the first fluid to the mixing chamber;
a bellmouth line in communication with the mixing chamber and the bellmouth; and
a first fluid line configured to be in fluid communication with the mixing chamber and the one or more extraction pipes such that a fluid from the mixing chamber comprising the water, the first fluid, or a mixture thereof is injected into the compressor via the one or more extraction ports,

wherein the air extraction system comprises a first configuration in which a portion of a flow of air in the compressor is extracted therefrom for use in cooling the turbine, and
wherein the air extraction system comprises a second configuration in which the water, the first fluid, or the mixture thereof is injected into the compressor via the one or more extraction ports when the wash system is attached to the air extraction system.

2. The system of claim 1 , wherein the first fluid source comprises a detergent source, and wherein the first fluid comprises a detergent.

3. The system of claim 1 , wherein the first fluid source comprises an anti-static solution source, and wherein the first fluid comprises an anti-static solution.

4. The system of claim 1 , wherein the mixing chamber comprises one or more angled counter flow nozzles therein, the one or more angled counter flow nozzles extending into the mixing chamber at an angle with respect to a central axis of the mixing chamber and configured to inject the first fluid at the angle in a direction counter to a flow of the water in the mixing chamber.

5. The system of claim 1 , wherein the water source is in communication with the mixing chamber via a water source line and the water pump.

6. The system of claim 1 , wherein the first fluid source is in communication with the mixing chamber via a first fluid source line and the first fluid pump.

7. The system of claim 1 , wherein the bellmouth line is in communication with a plurality of bellmouth nozzles positioned about the bellmouth.

8. The system of claim 1 , wherein the first fluid line comprises a quick disconnect valve in communication with the one or more extraction pipes.
