Step A:
Step B:
Step
c:
Check that oil
is
present
in
the diesel oil tank. Open the stop valves, which
connect the diesel oil tank to the oil system.
Select diesel oil on the manually. operated three-way valve (G 115). The
. control system will indicate diesel oil operation.
Open the stop valve from the burner return line to the mixing tube and close
the stop valve return to the oil tank.
Step D: Open the inlet stop valves, and the outlet non-return valves for the oil pumps.
Step E: Open the stop valves for the pressure gauges on the oil pumps.
Note:
The
stop valves for the
pressure
gauges on
the
pump
unit should only be
opened for
pressure
control purposes.
The
stop valves should be closed
during
normal
operation.
Step F: Open the quick closing valves for the burner unit.
Step G: Start one
of
the fuel oil pumps and set t4e other into stand-by mode
(if
two
are delivered).
Step H:· Check that the oil pressure in the ring line is at the correct level.
Step
I:
The burner
is
now ready for operation.
2.2 Heavy fuel oil mode
This section describes the actions, which must be carried out before the burner unit
and oil system are operational on heavy fuel oil.
Step A: Check that oil
is
present
in
the heavy fuel oil tank. Open the stop valves,
which connect the heavy fuel oil tank to the oil system. To avoid cavitation
of
the pumps, the viscosity
of
the oil in the heavy oil tank should not exceed
380 cSt.
If
necessary the oil tank should be heated.
Step B: Select heavy fuel oil on the manually operated three-way valve. The control
system will indicate heavy fuel oil operation.
Step C: Open the inlet stop valves, and the outlet non-return valves for the oil pumps.
Step D: Open the stop valves for the pressure gauges on the oil pumps.
Note:
The
stop valves for the
pressure
gauges on
the
pump
unit should only
be
opened for
pressure
control purposes.
The
stop valves should be closed
during
normal
operation.
Step E: Open the quick closing valves for the burner unit.
Step F: Start one
of
the fuel oil pumps and set the other into stand-by mode
(if
two
are delivered).
Step G: Check that the oil pressure
in
the ring line
is
at the correct level.
Step H: The burner
is
now ready for operation.
2.3
Normal start/stop
The
control system automatically stal1s, stops, and regulates the burner
in
normal op-
eration depending on the steam demand. When the steam pressure
is
below the set
point for operation, the burner commences the start-up sequence.
