Table 7: Oil nozzle capacity

All rates shown achieved with 120 PSIG pump pressure for Beckett and 140 PSIG pump pressure for Riello.

*Based on #2 domestic heating fuel oil having heating value of 140,000 BTU per gallon.

**Based on thermal efficiency of 84%-85%.

Table 8: Riello burner application

THE NOZZLE SIZE GIVES THE NOMINAL FLOWRATE, IN GPH, FOLLOWED BY THE SPRAY ANGLE, IN DEGREE’S, AND THE SPRAY PATTERN, EITHER “H” FOR HOLLOW CONE OR “S” FOR SOLID CONE. FOR EXAMPLE, A NOZZLE RATED AT 0.65 GPH @ 100 PSIG THAT PROVIDES AN 80° SPRAY ANGLE AND A HOLLOW SPRAY PATTERN WOULD BE ABBREVIATED IN THE TABLE AS “0.65 X 80°H”.

**NOTE: The reason the Riello burner nozzle sizes are smaller than the standard Thermo Pride burner nozzles is that pre-set pump pressures are higher, therefore achieving the same firing rate with a smaller nozzle.
