OIL CONTROLS
- Single Spill-back Nozzle
The oil control system comprises the burner mounted components and a fuel pump.
Note:
When a separate oil pumping set is used it is connected to the burner utilising the braided high
pressure hoses supplied. The burner lance incorporates hydraulic tip shut-off for the oil
nozzle whilst the system controlling valves are closely mounted at the burner head.
Oil Pumps Fitted:
MDFL 3300 - Suntec TA5C
MDFL 4000 - Suntec T2C
Manual Valve
A manual valve is fitted to the output of the fuel pump and must be closed before firing on gas.
Oil Nozzle
MDFL burners use a single oil nozzle (see drg) within the inner assembly (refer to the Appendix).
This nozzle is factory-specified to deliver optimum performance under the specified operating
conditions. Any queries regarding the size of the nozzle should be referred to Nu-way.
The nozzle is held in position by the inner assembly lance, through which oil flows from the manifold
block to the nozzle and recirculated through the spill regulating valve.
Oil Manifold Block
The oil manifold block is located on the left side of the hinged extension. It carries gauges which
indicate pump pressure, hydraulic pressure and spill pressure.
Oil Spill Regulating Valve
The oil spill is actuated by the motor which actuates the air damper. It varies the spill pressure in
order to provide the required oil flow rate at each operating condition.
Oil Pump
The oil pump is incorporated into a free-standing packaged unit, as shown schematically on page 17.
This package includes the oil filters and separation bottle.
