What does fuel atomization refer to in gas turbine operation?

Fuel atomization in gas turbine operation specifically refers to the process of breaking fuel into small droplets. This is a crucial step for efficient combustion. When fuel is atomized, it increases the surface area of the fuel, allowing for better mixing with air and enhancing the combustion process. By forming a fine mist, atomization ensures that the fuel can burn more completely and efficiently, resulting in more effective energy production and reduced emissions.

Other processes such as mixing fuel with coolant, converting fuel into gas, or filtering fuel to remove impurities do not relate directly to atomization. While they are important for different aspects of fuel management and engine performance, they do not involve the specific act of breaking down the fuel into smaller particles for optimal combustion, which is at the heart of the atomization process.
