RING SUPPLY LINE
(for heavy oil with viscosity up to 50°E at 50°C)
1 - Tank (heated for heavy oil)
2 - Filter (with resistance for oil > 7°E at 50°C)
3 - Forwarding pump
4 - Control manometer
5 - Shutter valves (in couple) excluding the burner
6 - Burner (provided for Kit for heavy oil code no. 3000721)
7 - Pressure adjuster
8 - Filter (with resistance for oil > 7°E at 50°C)
9 - Burner pump
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 at 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 at 50°C)
Notice: before placing the burner in operation, ensure that the return line is open. Any obstruction may damage the
pump seal.
