Return Nozzle Rod MAT
Functional description
The oil delivered by the burner pump will enter the feed pipe
(9) via the connection block (10).
Then it flows through the feed pipe (9) at the pre-set pressure
directly to the return nozzle. Part of the oil delivered will be
returned through the return flow pipe (6) via the return flow
hole of the nozzle.
The return flow rate is controlled according to the required
output using an output pressure control valve.
Approved shut-off valves are installed directly upstream of
the inlet to the nozzle rod in the oil feed and oil return lines.
