Additional Boiler Information

Boiler checks are recommended by ASME Code Section IV and adopted by the state of Tennessee. These boiler checks are recommended as a minimum and are not all inclusive. Additional checks may need to be made depending on the type, size, previous maintenance history, age and condition of the plant. All plants should be operated in a safe, prudent and attentive manner.

Inspection procedure checklists are provided below:

Low-Pressure Steam Boiler

Observe operating pressure
Observe water level
Observe general conditions
Determine cause of unusual noises or conditions and correct
Test water column or gage glass
Test water condition and perform corrections as necessary
(add chemicals, blow down, etc.)
Record in log

Test low-water fuel cutoff
Blow down boiler
Observe condition of flame
Check oil supply
Observe operation of condensate or vacuum pump

Safety valve -- lift lever
Test flame-detection devices
Test limit controls
Test operating controls
Sludge blow down (if required)
Check condition of heating surfaces for oil pre-heaters
Check combustion air supply to boiler room

Inspect internally and externally after cleaning
Open and inspect low-water fuel cutoff
Routine burner maintenance
Routine maintenance of condensate or vacuum return equipment
Routine maintenance of all combustion control equipment
Combustion and draft tests
Safety valve pop test
Evaporation test of low-water fuel cutoff
Inspect gas/oil piping for proper support and tightness
Inspect boiler room ventilation louvers and intake

Water Heater Boiler

Observe operating pressures and temperatures
Observe general conditions
Determine cause of unusual noise or conditions
Record in log

Observe condition of flame

ASME

Founded in 1880 by a small group of leading industrialists, the American Society of Mechanical Engineers (ASME) is a not-for-profit membership organization that enables collaboration, knowledge sharing, career enrichment, and skill development across all engineering disciplines. This assists global engineering communities develop solutions to benefit lives and livelihoods.

ASME is the approved standard for boilers and pressure vessels in Tennessee.

National Board

The National Board of Boiler and Pressure Vessel Inspectors was created in 1919 to promote a greater safety of life and property through uniformity in the construction, installation, repair, maintenance and inspection of pressure equipment. The National Board membership oversees adherence to laws, rules, and regulations relating to boilers and pressure vessels.

The National Board members are the chief boiler inspectors representing most states and provinces in North America, as well as many major cities in the U.S.
