3 Chapter 8 Boiler Operation Procedures Boiler operation information is communicated to the boiler operator starting the shift to specify any special procedures required.

4 Chapter 8 Boiler Operation Procedures When blowing down the gauge glass, water should enter the gauge glass quickly when the gauge glass blowdown valve is closed.

5 Chapter 8 Boiler Operation Procedures During a bottom blowdown, the boiler should be under light load and the water level should be at the NOWL.

6 Chapter 8 Boiler Operation Procedures The blowdown valve is opened to evacuate the low water fuel cutoff chamber with the burner firing during blowdown.

7 Chapter 8 Boiler Operation Procedures When testing the flame scanner, the flame scanner sensor is covered to simulate a flame failure.

8 Chapter 8 Boiler Operation Procedures Before starting the boiler for the first time, the boiler should have a minimum water level of approximately 2 above the bottom of the gauge glass.

9 Chapter 8 Boiler Operation Procedures The burner is started in low fire according to procedures specified by the manufacturer.

10 Chapter 8 Boiler Operation Procedures The boiler vent is closed when pressure in the boiler reaches 10 psi to 15 psi.

11 Chapter 8 Boiler Operation Procedures The main steam stop valve is opened slowly to allow the pressure to equalize when the boiler is a few pounds below the header pressure.

12 Chapter 8 Boiler Operation Procedures A broken or discolored gauge glass is replaced using standard procedures for maximum safety.

13 Chapter 8 Boiler Operation Procedures The low water fuel cutoff controls must be installed vertically for proper performance.

14 Chapter 8 Boiler Operation Procedures The burner is maintained and tested to ensure proper operation and maximum efficiency.

15 Chapter 8 Boiler Operation Procedures Feedwater pumps should be checked periodically to ensure proper bearing temperatures and checked for any unusual vibration.

16 Chapter 8 Boiler Operation Procedures Safety valves are routinely tested to ensure proper operation and must be serviced by an authorized manufacturer representative.

17 Chapter 8 Boiler Operation Procedures Steam traps are checked for proper operation when determining the cause of a steambound feedwater pump.

18 Chapter 8 Boiler Operation Procedures When inspecting a boiler, inspect tube sheets, tubes, and other internal parts for corrosion, overheating, and/or other damage.

19 Chapter 8 Boiler Operation Procedures Handhole covers are removed to provide access to boiler parts during a boiler inspection.

20 Chapter 8 Boiler Operation Procedures All internal surfaces are exposed and cleaned prior to the boiler inspection.

21 Chapter 8 Boiler Operation Procedures Troubleshooting steps from the manufacturer provide a guide to correcting a boiler operation problem.

22 Chapter 8 Boiler Operation Procedures The boiler room log lists boiler operation data that can be used to increase boiler efficiency and identify a potential malfunction.
