FLUIDICS NOZZLE WITH PINLESS NOZZLE
For the burner's diesel operation, use a FLUIDICS pinless nozzle type
12 N2 45° of suitable size depending on the burner's capacity.
CAUTION / WARNINGS
At first burner ignition, the return nozzle must be never fully clo -
sed.
When the nozzle operates at maximum output, the difference
between delivery and return must be of 2-3 bar.
Example
Pump pressure 20 bar
Return pressure 20-2 = 18 bar
Return pressure 20-3 = 17 bar
Pump pressure 22 bar
Return pressure 22-3 = 19 bar
Return pressure 22-2 = 20 bar
FI N2 130 45° 0607
Marking on the hexagon:
FI = manufacturer
N2 = nozzle type
*130 = flow rate
45° = spray angle
0607= Manufacturing date
*Example flow rate, not specific for any burner in this manual.
The diagrams represent the curves showing the values of the fuel flow
rate delivered by the nozzles depending on the return pressure.
The curves were obtained by considering a diesel pump regulating
pressure of 25 bar.
Return pressure value is detected on the pressure gauge (3) with 0-40
bar scale.
