Light oil nozzles
The fuel rate is adjusted by choosing a properly dimensioned nozzle (spill-back type) and adjusting the inlet and return pressure fol-
lowing the directions showed in the next table.

FLUIDICS NOZZLES
Example: as for over 100kg/h nozzles, the 80% of the nozzle flow rate can be obtained with a return pressure at about 18bar (see Fig.
14).
