Chapter 2 Boiler Operation
2-1 Check Item before Operation
* Before start the operation, check the following items:
(1) The gauges(whether the pressure gauges, oil pressure gauges and water level gauges are working in
the normal condition).
(2) Water level in the feed water tank before opening the feed water valve;
(3) Oil level in the oil tank before opening the valve;
(4) Cleaning detergent in the chemical injection tank;
(5) Quality of soft water.
2-2 Operation Start
(1) Main switch for boiler “ON”.
(2) The power switch “ON” on the control panel equipped with the
front side of the boiler.
(3) Check that the water level on the water level gauge is normal, and
water is feeding automatically.
(4) Operation switch “ON” on the control panel.
(5) Push the manipulation switch(push button) for boiler operation.
(6) Check ignition condition in the low and high fire through the
reflection mirror after normal operation.
(7) Open the main steam valve slowly when the steam pressure is
reached up to 3 Kg/cm2.
(Control panel)
2-3 Operation Stop
(1) Operation switch “OFF”.
(2) Power switch “OFF” after post purge.
(3) In case of using bunker C oil, it is to be ignited by the light oil for 10 minutes before operation
suspension.
(4) Close the fuel valve and the main feed water valve.
2-4 Cautions during operation
(1) Open the main steam valve slowly.
(if open the valve rapidly, the water level in the tube could be the low level temporarily).
(2) In the event that the operation is stopped through sensing of the thermistor due to superheating of
the boiler main body, the operation switch and the power switch is to positioned to “stop” and close
the main fuel valve slowly.
