BERGONZO NOZZLE WITHOUT PIN
For light oil operation, use nozzles of BERGONZO B5 45° model wi-
thout pin for 900 kg/h, depending on the maximum regulated thermal
rate.
The diagrams below represent the curves showing the values of the
fuel flow rate delivered by the nozzles depending on the return pres
-
sure.
The curves were obtained by considering a diesel pump regulating
pressure of 25 bar.
The return pressure value is to be measured on the pressure gauge
with 0-40 bar scale according to the diagram.
