Start-up
To continue the commissioning procedures, the oil system must
be
in
normal operation.
Prior to the actual start-up
of
the burner, some additional checks should be carried out
with regard to ignition and start-up
of
the burner. When these checks are completed,
the burner should be commissioned on diesel oil and finally on heavy fuel oil.
Attention: Before
and
during
start-up,
the
furnace
must
be checked with
regular
intervals for oil spillage.
If
an
oil spillage is
present
in
the
furnace,
the
cause
must
be
determined
and
the
failure
must
be rectified.
The
fur-
nace should be
purged
until
it
is free
of
oil.

Additional
commissioning
checks
2.1.1
Check
the
burner
motor
Step A: Rotate the burner motor
by
hand to ensure a free and an uninterrupted rota-
tion.
Step B: Adjust the circuit breaker for the burner motor to suit full load current
of
the
motor. The current appears from the motor identification plate and/or the
electric diagrams.

unit.
Step D: Start the ring line fuel oil pump.
Step E: Operate the burner as described
in
the chapter "Manual operation" Press the
"BURNER MOTOR" push button.
Step F: Check that the burner motor is running with the correct direction
of
rotation.
Step G: Check that the burner motor does not produce any abnormal mechanical
noises or vibrations.
2.1.2
Check
the
ignition electrodes
Step A: With the burner motor running press the "IGNITION" push button and keep
it pressed. The ignition transfornler will
be.
energised and the electrodes
ignite.
Step B: Check that the ignition spark appears, re-adjust the electrodes,
if
necessary,
as described the section "Commissioning adjustments
of
the burner unit".
Step C: Stop the burner motor after the check procedure has been carried out.
2.2
Commissioning
on
diesel
oil
When the burner
is
commissioned, the boiler pressure and temperature must not
be
intensified too rapidly
as
this might cause stresses
in
the boiler. The burner should
be
kept in minimum firing position during the first commissioning period. The burner
should also only be operated at relatively short intervals during the initial start-up.
When the burner
is
stopped during this firing-up procedure, the safety interlock shut
downs can
be
checked and adjusted .
