FUEL BURNER SYSTEM
The fuel oil flow system is a conventional “two-pipe”
oil burner flow which assures automatic priming of
the fuel pump and never a loss of prime as long as
fuel is in the tank. The burner fuel is being pulled
from the fuel tank through the fuel filter by the fuel
pump. The fuel pump sends the burner fuel (the fuel
is now pressurized to 100 PSI) though a burner
solenoid, a burner tube, and into the fuel nozzle
where it is again filtered and atomized (sprayed) to a
fixed pattern into the combustion cone.
The burner solenoid will allow fuel to pump
through the burner nozzle when the burner switch is
on, tool valve is open and water is flowing through
the system. The flow switch activates the burner
solenoid when water is flowing.
When the engine is running, combustion air is
always present. The atomized fuel is ignited by a
high voltage constant spark which is generated by
the magneto.
