Light oil nozzles
The light oil fl ow rate can be adjusted choosing a by-pass nozzle that suits the boiler/utilisation’s output and setting the delivery and
return pressure values according to the values quoted on diagram on Fig. 9.
Example (Bergonzo):
if a 220kg/h flow rate BERGONZO nozzle is provided, set the return pressure at 11bar, supply at 20bar on the
delivery to get a 220kg/h flow rate. If the return pressure needed is 5bar, instead, act on the
V
adjusting screw on the pressure gover-
nor (see chapter on page 18). The flow rate will then be about 95kg/h (see the example showed on the Bergonzo diagram).
