What pressure is the oil supplied to the burner mechanical atomizing nozzle?

The oil supplied to the burner mechanical atomizing nozzle is typically provided at a pressure of 700 kPa (100 psi). This pressure is crucial for ensuring that the oil is properly atomized into a fine mist, which is essential for efficient combustion in heating systems.

At this specific pressure, the viscosity of the oil is effectively reduced, allowing for an even distribution of the fuel. A sufficient atomization helps enhance the combustion efficiency, minimizing unburned fuel and potentially harmful emissions.

Recognizing the importance of pressure in atomization, if the pressure were too low, oil would not be atomized adequately, leading to larger droplets that could result in incomplete combustion and increased emissions. Conversely, excessively high pressure could lead to excessive wear on the nozzle and other components, along with potential safety risks. Hence, the most efficient and safe operating pressure for the mechanical atomizing nozzle aligns with the chosen answer.
