Fuel oil supply
To facilitate the fuel flow, all pipes must be suitably
dimensioned, insulated and heated (electrically or through
vapour or hot water).
To limit the formation of gas or vapour, the fuel pressure in
the degassing unit 10) must be adjusted according to the
supply temperature as per the table above.
The transfer pump must have a flow rate that is at least twice
the burner pump one.
For several burners supplied by the same loop, the pump
must ensure a supply of approx. 30% more than the sum of
flow rates of the single burners.
For start-up
: with burner disabled through gate valves 5)
make fuel flow in the supply loop. Once standard circulation
is reached, open the gate valves and regularly supply the
burner.
Key
Variation for secondary power supply
The degassing unit for tick oil must be equipped with heater code
3010050
.
Tab. I
Explosion danger due to fuel leaks in the
presence of a flammable source.
Precautions: avoid knocking, attrition, sparks and
heat.
Make sure the fuel shut-off valve is closed before
performing any operation on the burner.
ATTENTION
The fuel supply line must be installed by qualified
personnel, in compliance with current standards
and laws.
ATTENTION
Before starting the burner make sure that the
return pipe line is not clogged.
Any obstruction would cause the pump seals to
break.
Oil pipes must be completely airtight.
