Which burner design is NOT typically used for burning oil?

The stoker-type burner is primarily designed for burning solid fuels, like coal or biomass, rather than liquid fuels such as oil. Stoker burners function by feeding solid fuel into the combustion chamber in a controlled manner and are not compatible with the delivery and combustion characteristics of liquid fuel.

On the other hand, steam atomizing burners, air atomizing burners, and mechanical atomizing burners are all specifically designed for the efficient burning of liquid fuels like oil. These types of burners use various methods to atomize the fuel, creating a fine mist that mixes with air to ensure optimal combustion and energy efficiency. The atomization process is crucial for liquid fuels as it allows for better mixing with the combustion air and promotes complete burning, minimizing emissions and maximizing energy output.

Thus, the stoker-type burner stands out as the design that does not fit the requirements for burning oil, making it the correct identification in this question.
