ABSTRACT
Atomization is a process of breaking up bulk liquid into many small droplets. In order to have good combustion, fuel and air must mix well. A bulk liquid has a limited surface area to contact with the air. This is the reason that liquid fuel, or, more specically, fuel oil, requires atomization before burning. Atomization increases liquid surface area, which results in an increase of fuel evaporation rate and fuel-air mixing rate. This improves the combustion process.
