DIAGRAM OF A DISMANTLED ( C.B. ) CHARLES BERGONZO NOZZLE (WITHOUT PIN)
Nozzle rating data:
Flow rate kg/h
Spray angle (30° - 45° - 60° - 80°)
Output ratio (1/3 = B3 - 1/5 = B5)
Fuel outlet hole
For the nozzle to operate properly, its "return" section must never be completely closed. This condition must be implemented properly
when igniting the burner for the first time. In practice when the nozzle is operating at the maximum desired output, the difference
between "delivery" to nozzle (pump pressure) and "return" from nozzle (pressure at the return pressure regulator) pressure must
be at least 2 ÷ 3 bar.
Example

Fuel outlet
Pump pressure 20 bar
Return pressure 20 - 2 = 18 bar
Return pressure 20 - 3 = 17 bar
