The oil furnace nozzle
|
|
The nozzle is a device used to atomize the fuel oil into very small droplets. The smaller the droplets, the better the oil burns. The oil is lit by a high temperature spark which vaporizes and heats a small amount of the oil. Once the spark lights some of the oil, the heat released vaporizes and lights the rest of the oil.
The pressure used to atomize the oil is critical to completely atomizing the oil. Most pumps run at a minimum of 100# with newer pumps running higher pressures.

This an illustration of the nozzle at various pressures.
Note the droplets are smaller as the pressure increases.
The smaller the droplets the easier the oil evaporates.
The video below shows a nozzle at different pressures, showing the difference as the pressure increases.

Nozzles are rated for oil flow at gallons per hour at 100# pressure.
Many newer burners run at higher than the 100# pressure.
Below there is a chart that gives approximate gallons per hour of varying pressures higher than 100#.
