Min. oil inlet pressure to burner
2.5 bar or higher depending on oil
temperature at the pump. See illustration.
In-let oil temperature range: Heavy fuel oil
60 - 100 C°
Pump operating pressure (=atomizing
pressure) for heavy fuel oil
25 - 30 bar
Pump operating pressure (=atomizing
pressure) for light fuel oil
20 - 25 bar
.
Note! 1 bar = 100 kPa.
