How is cleaning typically performed on a gas turbine?

Cleaning a gas turbine by running a liquid or abrasive through the blades is a common practice to remove deposits and improve efficiency. This method allows for the effective cleaning of the turbine while minimizing downtime, as it can often be done without completely taking the turbine offline.

The process usually involves using specially formulated cleaning solutions or water that can help dissolve accumulated debris, such as dust, salt, and other contaminants that may have built up on the blades. By directing these cleaning agents through the turbine, operators can restore optimal airflow and combustion efficiency, which can significantly enhance performance and reduce fuel consumption.

In contrast, other options such as taking the unit offline and washing each section individually can be more time-consuming and may lead to longer outages. Injecting cleaners into the gas or fuel system might not adequately address the deposits directly on the blades, limiting effectiveness. Shutting down the rotor does not contribute to cleaning but rather interrupts operation without addressing the cleaning needs of the turbine. Therefore, utilizing liquid or abrasive cleaning while the turbine is running stands out as the most efficient and effective approach for maintaining gas turbine performance.
