17. Burner Shutdown
Normal operation of the burner will allow the operating
controls to shut the burner down when the load demand is
satisfied. If the burner needs to be shut down for any rea-
son, the “ON-OFF” switch can be used to quickly turn the
burner off. This will instantly cause the fuel valves to close
and start a post purge cycle to remove any unburned fuel
from the vessel.
In an emergency shutdown, all fuel and electrical power
should be de-energized or turned off to secure the burner.
This would include the main power disconnect, the manu-
al gas shutoff valve at the drop down line and if equipped,
the manual oil valve to the nozzle.
It is recommended that the burner be manually driven to
low fire before turning the burner off, as this reduces the
dynamic and thermal stress. If the burner will remain off
for some time, the manual fuel valves, fuel pumps and
power supply should be turned off.
CAUTION
ALWAYS KEEP THE FUEL SUPPLY VALVE SHUT OFF WHEN THE
BURNER IS SHUT DOWN FOR AN EXTENDED PERIOD OF TIME.
18. Restarting after Extended Shutdown
Extended shutdowns require the same startup process as
those outlined above. In addition, the following advanced
cleaning must be done,
a. The air atomized oil nozzle should be removed and
cleaned, if pressure atomized they should be replaced.
Use care in cleaning to preserve the sharp edges of the
nozzle, which are required to maintain good atomization.
b. The oil filter and strainer must be removed and cleaned
prior to starting.
CAUTION
DO NOT START THE BURNER UNLESS ALL CLEANOUT DOORS
ARE SECURED IN PLACE.
