CHOOSING THE INJECTOR
The injector must be chosen according to the power rating of the boiler flue, remembering that heating
oil has a heat value (N.H.V.) of 10200 kcal/Kg. The chart gives the flow rate or consumption in Kg/h and
kW of heating oil according to the size of the injector (in GPH) and the pump pressure (in bar). When the
burner has a preheater, the effective capacity will be about 10% lower than the values in the chart.
