Nozzles selection
Inside every PUMP/NOZZLE PRESSURE box there are two values. The flow rate in kg/h is expressed at the top,
in kW at the bottom.
Dual-pipe supply
Example: the boiler to which the burner must be coupled has a power at the firebox of 580 kW.
The burner functions at 12 bar and has three-stage functioning, therefore three nozzles. The flow rate must be
fractioned with the following nozzles:
1 nozzle with 5 GPH on the second flame that at 12 bar develops 240,76 kW
1 nozzle with 7 GPH on the first flame that at 12 bar develops 336,82 kW
Total of the three nozzles: 577,6 kW, as requested by the boiler.
If the best nozzle is not available, by acting on the regulation it is possible to vary the pump pressure in order
within the limits of 11 - 14 bar, to obtain the desired flow rate.
N. B.: If the piping length exceeds 60m, a supply pump is recommended - d10 (2), d12 (2): for two flame burners..
