CFESA- Steam Study Guide Chapter 3 -
Boilers and Steam Generators
1.What are the four inspections performed on a boiler as it is manufactured? - answera.
Steel is inspected before it is shipped; the fit up of a boiler shell is inspected after it is
tack welded. The welding inspection after the boiler has been welded and the hydro-
static pressure test.
2.How is a boiler plate steel identified? - answera. The inspection code is printed on it.
3.What is hydro-static testing? - answera. Resting of the boiler at certain water
pressures at certain temperatures.
4.Who is responsible for inspecting boilers? - answera. Certified boiler inspectors
employed by the state or in some cases by the specialty insurance companies.
5.What is a boiler license and who requires it? - answera. A boiler license is required in
many states or local jurisdictions in order to buy, install or service any pressure vessel.
6.Why is there even a need for boiler licenses? - answera. Boiler licenses are needed to
ensure that those installing or servicing steam pressure vessels are qualified and
knowledgeable of the codes, and service procedures. Pressurized steam equipment
can cost lives and serious injuries if a serious accident occurs.
7.What is boiler permit? - answera. A boiler permit is an approval to install or modify a
steam pressure vessel. In the food service sector, this can include boiler bases and any
kind of steam kettle, whether direct steam fired or self-contained.
8.Who can legally weld boilers? - answera. Certified boiler welders
9.What is an "R" stamp? - answera. An "R" stamp is a designation certifying that the
holder has the experience and knows the proper codes and methods of making safe
repairs to any boiler pressure vessel.
10.What is the difference between a steam boiler and a steam generator? - answera. A
steam boiler operates under pressure and a steam generator creates steam under no
pressure
11.At what pressure do steam generators usually operate? - answera. 212◦F
12.What is the most common reason that steam generators need to be replaced? -
answera. Scale build up and corrosion
