HEAVY OIL SUPPLY LINE
RING SUPPLY LINE
For heavy oil with viscosity up to 50°E/50°C.
1 - Tank (heated for heavy oil)
2 - Filter (with resistance for oil > 7°E/50°C)
3 - Forwarding pump
4 - Control manometer
5 - Shutter valves (in couple)
excluding the burner
WARNING
- The oil could easily flow through the pipes if those are properly seized, protected and heated (by electricity,
steam or hot water).
- The forwarding pump capacity should be all the least double of that of the burner pump.
If several burners are supplied through the same ring supply line, the forwarding pump should have a capacity
of approx. 30% more than the sum of the single burners outputs.
- For starting-up: after excluding the burner by the shutter valves (5) let the oil flow into the supply ring up to
reach the required circulation; after than open the valves and supply normally the burner.
GRAVITY SUPPLY LINE
Only for oil with max. viscosity up to 7°E/50°C.
Attention:
before placing the burner in operation, ensure that the return line is open. Any obstruction may damage the pump
seal.
