This report will provide instructions for the use of a Combustion Engineering single-burner saturated-steam auxiliary boiler. Topics covered will be limited to lighting off the boiler, raising steam, and cutting the boiler in on the steam line.

1. Water in the steam drum should be brought to a level below mid-height in the gage glass. To achieve this, open all air vents to the drum and then open the bottom blow valve. When the water level is at the appropriate level, close the bottom blow valve.
2. Line up feed water supply. Check to be sure that all valves along the feed water supply line are open except for the final valve.
3. Line up fuel supply. Check to be sure that all valves along the fuel oil supply line are open except for the final one just before the burner. Note: If the boiler has a return-flow style burner, also check the return flow line to be sure that all valves are open along this line except for the back-pressure valve just after the burner.
4. Install the burner with the smallest tip. This process will involve checking the atomizer tips to see what number is engraved on them. The highest number tip is the smallest and should be used.
5. Examine the fuel oil strainer to be sure that the straining element is clear of debris and can function properly.
6. Line up air supply.
7. Purge furnace. Run forced draft fan for at least one minute to clear the furnace of hazardous gases.
8. Light torch using a lighting element soaked in fuel.
9. Light off furnace by putting the torch down the lighting shaft and starting the fuel oil pump and forced draft fan.
10. If the furnace will not light after a few seconds, retract the torch and return to step seven (purging the furnace).
11. After the furnace is lit, adjust back pressure and draft damper to achieve a clean burning flame. If the flame is sparking, too much air is present.

1. Continue to burn the furnace.
2. Adjust the flame to keep it clean and keep a clear furnace. The back wall of the furnace should be visible and the stack should be nearly clear of soot.
3. If necessary, switch to a higher-capacity burner to achieve more heat.

1. When steam pressure is at 75psi or above, close the drum vent.
2. Crack the steam stop valve to allow a small amount of steam to pass through and warm the pipes along the steam cycle.
3. Open the feed water valve to allow enough feed to flow into the drum to compensate for the steam leaving.
4. After at least one minute, fully open the steam valve and commence operation of turbines.
