What is one purpose of auxiliary systems on gas turbines?

Auxiliary systems on gas turbines play a crucial role in supporting the primary operations of the turbine and ensuring its efficiency and reliability. One of the main purposes of these systems is to provide crucial support functions that enhance performance and maintenance.

Providing fuel at the proper temperature is vital for ensuring optimal combustion within the gas turbine. If the fuel is too cold, it may not vaporize correctly, leading to inefficient combustion and reduced turbine performance.

Injecting steam to clean the ducts is another function that helps maintain the efficiency of the turbine. Over time, deposits can accumulate in the turbine ducts, which can negatively impact airflow and efficiency. Steam cleaning can help remove these deposits, restoring optimal performance.

Additionally, providing hydraulic fluid for lubrication is essential to prevent wear and tear on moving parts within the turbine. Proper lubrication ensures smooth operation, reduces friction, and prolongs the life of critical components.

In summary, auxiliary systems encompass a wide range of functions, all of which are vital for maintaining the overall performance and longevity of gas turbines, making "all of the above" the correct response.
