ABSTRACT:
Light fuel oil of low viscosity is supplied to a pressure atomizing oil burner. A flow heater which is positioned upstream of the pressure atomizing nozzle, preheats the fuel oil to a temperature of approximately 150.degree. C. but not over the coking and cracking temperature of the fuel. With heat efficiencies up to approximately 25,000 kcal/hour density and viscosity are continuously decreased in the flow heater in order to reduce the thickness of the oil film leaving the atomizing nozzle and thus to decrease the flow rate.
With heat efficiencies higher than approximately 25,000 kcal/hour density and viscosity are decreased before the ignition phase by preheating, in order to reduce the thickness of the oil film flowing out of the atomizing nozzle and thus to decrease the flow rate in the following ignition phase. After the ignition phase the preheating is reduced or stopped.
