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)
NOTE: For proper nozzle operation, it is important that the “return” is never 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 Pump pressure 20 bar Pump pressure 22 bar
Return pressure 20 - 2 = 18 bar Return pressure 22 - 3 = 19 bar
Return pressure 20 - 3 = 17 bar Return pressure 22 - 2 = 20 bar
