CHOOSING THE NOZZLE
The choice has to be made according to the power of the boiler furnace, considering that the light oil has a calorific power
of 10200 kcal/kg. The table indicates the theoretic capacity or consumption, in kg/h and kW of light oil according to the
size of nozzle (GPH) and to the pressure of the pump (in bars). In burners with two nozzles, the capacity is subdivided for
40% on the nozzle of first flame, and for 60% on the second nozzle.
EXAMPLE CHOOSING THE NOZZLE
The boiler has a power in the furnace of 290 kW.
For a pump pressure of 12 bar, the nearest value is kW 288,80 to which a 6 GPH nozzle is corresponding. Should the
burner have two nozzles, share the capacity with a 2,50 GPH nozzle on the first flame and with a 3,50 GPH nozzle on
the second flame.
When the optimal nozzle is not available, the pressure of the pump may be varied between the limits of 11 – 14 bars, in
order to achieve the wished capacity.
INSTALLING THE NOZZLE
After choosing the proper nozzle, proceed to installing it as shown in the paragraph “MAINTENANCE”.
