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.
