Load distribution
The load distribution of the burner is made via a pressure change-over on the oil
pump.
Generally, stage 1 takes on approx. 65 % of the maximum oil throughput, a different
distribution may be necessary.
Example
Burner capacity required: approx. 335 kW
65 % of burner capacity required: 335 kW × 0.65 = 218 KW
Nozzle size 5.00 gph, see nozzle selection table:
Stage 1: 10 bar (226.1 kW)
Stage 2: 22 bar (335.6 kW)
