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 20 bar Pump pressure 22 bar
Return pressure 20 - 2 = 18 Return pressure 22 - 3 = 19 bar
20 - 3 = 17 22 - 2 = 20 bar
