Open day today and after some tweaking, the boiler met all expectations. With six machines running, the high/low fire was modulating at 99 -94 PSI, and steam pressure was modulating 99 - 85 PSI.
For record, the following parameters are noted:
Oil pressure at Burner input = 8 PSI.
Oil pressure at High-fire nozzle = 14 Bar (reduced from 16 Bar)
Oil temperature = 190 degrees F.
On-board oil lock out thermostat set 90 deg.
On-board oil heater thermostat set 100 deg.
(these two readings indicate the thermostat indicator scale and do not indicate actual oil temp)
Back-end temp = 800 deg +/- 10 degrees.
Back-end explosion flap set at open 30mm at the flap lowest measurable position.
