A burner with a mechanical sprayer plate uses which of the following for atomizing?

A burner with a mechanical sprayer plate atomizes fuel by utilizing air. The process of atomization involves breaking the fuel into small droplets to create an efficient mixture with air for combustion. In mechanical atomization, the fuel is forced through a small opening, where it encounters a stream of air that helps to disperse the fuel into fine droplets. This is crucial for achieving a stable and complete combustion process, as the mixture needs to be thoroughly mixed to maximize the efficiency of the burn and minimize emissions.

Using air for atomization is advantageous because it is readily available and provides the right conditions for effective mixing with fuel. Other options like water, steam, or carbon dioxide would not create the necessary environment for optimal combustion in this scenario, as they either do not mix effectively or may dilute the fuel too much for a proper burn.
