How does a rotary cup burner atomize fuel?

• A. By high-pressure air
• B. By means of a spinning cup/high velocity air
• C. Through an electric discharge
• D. Using mechanical agitation

Answer: (B)

A rotary cup burner atomizes fuel by using a spinning cup in conjunction with high-velocity air. This method involves the fuel being drawn into a rotating cup, where it is flung outward due to centrifugal force. As the fuel is ejected from the cup, it encounters a stream of high-velocity air, which helps to break the fuel into fine droplets, creating an efficient atomization process. This technique is particularly effective because the combination of rotational motion and air pressure ensures that the fuel is atomized into very small droplets, enhancing the combustion process. The finer the droplets, the more surface area is available for mixing with air and burning, leading to improved fuel efficiency and reduced emissions in the heating process. This type of burner is common in applications where efficient combustion and heating are critical, demonstrating how the design maximizes performance through both mechanical and aerodynamic principles.
