Gas/air bubbles in oil
When oil is drawn up from the oil tank
to the burner, large amounts of gas
bubbles can be released from the
oil. These gas bubbles are released
when there is a negative pressure
(vacuum) in the suction line. The quality,
temperature and viscosity of the oil will also play a determining role in the amount of gas
released. This occurs in almost every installation, but above all when oil must be lifted to a
higher level and/or drawn through long suction lines. The gas/air bubbles ow with the oil
into the oil pump and are the leading cause of breakdowns. Gas/air bubbles also lead to
an increased build up of soot, reduced efciency, increased emission of harmful particles,
unnecessary wear and tear on the oil pump and higher oil consumption.
The two-pipe system was developed to try and get rid of the gas/air bubbles from the
oil pump. A return line pumps the separated gas/air bubbles together with the unburned
oil from the oil pump back to the oil tank. This, however, does not reduce the amount of
gas/air bubbles that ow to the nozzle for combustion, which results in nozzle problems
(see page 4). The high ow of oil in the two-pipe system (up to 20 times more than what
is actually used for combustion) leads to increased dirt/sludge being released from the oil
tank leading to clogged oil lters and nozzles.
