What does the ASME code stand for and what does it do?
a) ASME stands for Associated Social Mechanics and Engineers
b) ASME stands for Ameican Society of Mechanical Engineers, enforces
Boiler and pressure vessel construction and maintenance
c) ASME stands for Ameican Society of Mechanical Engineers and gives
codes for boiler and pressure vessel construction/maintenance
c) ASME stands for Ameican Society of Mechanical Engineers and gives
codes for boiler and pressure vessel construction/maintenance
Who is NBBI and what do they do?
a) The National Board of Boiler and Pressure Vessel Inspectors, enforces
ASME laws, rules, and regulations relating to boilers and pressure vessels
b) The National Board of Boiler and Pressure Vessel Inspectors oversees
adherence to ASME laws, rules, and regulations relating to boilers and
pressure vessels
c) The National Board of Boiler and Pressure Vessel Inspectors, creates
ASME laws, rules, and regulations relating to boilers and pressure vessels
b) The National Board of Boiler and Pressure Vessel Inspectors was
created in 1919 to promote greater safety to life and property through
uniformity in the construction, installation, repair, maintenance, and

,What does "simmering" mean in relation to boilers?
a) when a boiler is almost at boiling, but not at a full boil yet
b) leaking valve on a boiler
c) Slight leaking due to improper seating of the Safety-valve disk
c) Slight leaking due to improper seating of the Safety-valve disk
what is a "huddling chamber" on a safety valve?
a) a safety valve has a huddling chamber, located between the valve seat
and atmosphere which confines steam, thus increasing upward load,
lifting the spring higher and providing a closing snap .
b) a place for steam to escape when the valve is lifted thus providing an
efficient release of pressure to quickly reduce pressure in a boiler
c) place for steam to accumulate at higher temperatures to more quickly
be released to the atmosphere, reducing pressure in a boiler faster
a) a safety valve has an adjustable pop, or huddling chamber, located
between the valve seat and atmosphere which functions to confine
steam temporarily, thus increasing the upward load, lifting the spring
higher and providing a subsequent closing snap with pressure reduction.
What is blowback or blowdown on a safety valve?
a) blowdown, or blowback is the released steam and hot water released
when safety valves are open
b) The difference between actual popping pressure of a pressure relief
valve and reseating pressure expressed as a percentage
c) the difference between the opening and closing pressure of a safety
release valve
b) The difference between actual popping pressure of a pressure relief
valve and reseating pressure expressed as a percentage
c) Blowback or Blowdown is the difference between the opening and
closing pressure and is expressed as a percentage of working pressure
,what is the purpose of a low limit control on a hot water heater?
a) low limit controls are not used on hot water boilers
b) this control will not allow the burner to leave its low fire position until
the temperature in the boiler has passed 150 degrees
c) a low limit control will decrease the pressure on the system
b) this control will not allow the burner to leave its low fire position until
the temperature in the boiler has passed 150 degrees
if you passed a state boiler exam for 1st class, grade c engineer, what
equipment would your license allow you to operate?
a) total horsepower of 250 psi
b) boilers up to 500 hp and hot water boilers not to exceed 250 degrees
F or 160 psi steam boilers not to exceed 15 psi
c) Hot water boilers above 250 f or 160 psi and steam boilers above 15
pis
b) boilers up to 500 hp and hot water boilers not to exceed 250 degrees
F or 160 psi steam boilers not to exceed 15 psi
would a safety relief valve installed on a hot water boiler relieve all the
pressure if the boiler was low open water and the water was flashing into
steam?
a) yes
b) yes because of the A.S.M.E. code
c) no, because such a valve may be sized to handle liquids only.
c) if the boiler was approved by the A.S.M.E.
b) yes because of the A.S.M.E. code
, with a current state of MN Chief Engineer's license (grade C) you would

water and 15 psi steam
b) boilers of unlimited hp and above 250 degrees F or 160 psi hot water
and at 15psi steam pressure.
c) boilers of unlimited hp above 15 psi, but below 250 degrees F or 160
psi hot water.
a) boilers of unlimited hp not to exceed 250 degrees F or 160 psi hot
water and 15 psi steam
What firing control will prevent thermal shock to a hot water boiler?
a) a low limit control
b) an operating control
c) a high limit control
d) none of the above
a) a low limit control
can high temperature high pressure hot water be converted to low
pressure steam?
a) yes, by using a larger pipe
b) no, it cannot be done.
c) yes, with the use of a heat exchanger
c) yes, with the use of a heat exchanger
comparing hot water boilers to steam boilers, what auxiliaries are
eliminated?
a) steam traps, condensate tanks, D.A. tanks
b) both systems need the same auxiliaries
c) strainers and reciprocating pumps
a) steam traps, condensate tanks, D.A. tanks
