Pressure atomizing burners atomize fuel oil using _______.

Pressure atomizing burners use a nozzle to atomize fuel oil, which means converting the liquid fuel into tiny droplets that can mix more easily with air for better combustion. In a pressure atomizing system, the fuel oil is pumped at high pressure through the nozzle, where it is forced through a small opening. This process causes the fuel to break apart into fine particles, thereby enhancing the efficiency of the combustion process.

The design of the nozzle is critical because it not only determines the size of the fuel droplets but also impacts the distribution of the fuel-air mixture in the combustion chamber. Proper atomization leads to a more complete combustion, which improves energy efficiency and reduces emissions, making it a key component in steam boiler operations and other industrial applications.

Other components, such as diffusers or vaporizers, play different roles in combustion systems but do not serve the primary function of atomizing fuel oil as effectively as a nozzle. A pump is responsible for supplying the fuel under pressure, but it is the nozzle that actually performs the atomization needed for optimal combustion.
