N.B. For the nozzle to operate properly, its "return" section must never be completely closed.
This is achievedby regulating when the burner is started up for the first time. In practice, when the nozzle is operating at the maximum flow rate,
the difference in pressure between the "delivery" (pump pressure) and "return" (pressure at hte returnpressure regulator) pressures (running to
and from the nozzle) must be at least 2÷3 bar.
Example: Pump pressure
