Nozzle
The nozzle can be defined for all intents and purposes as the heart of the combustion system. The operation
of the entire machine depends on its correct operation. The fuel passes through it and, under the effect of the
pump pressure, it expands through the outlet, becoming finely vaporised.
Figure 9 - Nozzle for diesel oil and kerosene.
The nozzle has data written on it such as the flow, in US Gal/hr or Kg/hr, that leaves the outlet at a
conventional pressure.

Figure 10 - Cleaning the nozzle with a jet of air into the outlet.
Never replace the nozzle with one having different characteristics. Always use original spare parts. If the
nozzle is not working correctly, clean it using compressed air as shown in the figure.
The nozzle type is defined based on the type of heater (SEE TABLE).
