What is the primary function of the atomizer in main propulsion boilers?

The primary function of the atomizer in main propulsion boilers is to divide the fuel oil into fine particles for combustion. This process is critical because effective combustion of fuel oil requires it to be atomized into small droplets, which allows for better mixing with air and increases the surface area for combustion. By producing these fine particles, the atomizer ensures that the fuel can ignite more readily and burn more completely, leading to improved efficiency and reduced emissions.

Proper atomization is essential for optimal boiler operation, as it directly impacts the performance and efficiency of the burning process. If the fuel is not atomized correctly, it can result in incomplete combustion, leading to inefficiency, increased fuel consumption, and potential damage to the boiler system.
