SCRIPT QUESTIONS AND SOLUTIONS RATED A+
✔✔What would the pyrometer tell you? - ✔✔The temperature
✔✔An aqua state would be used on what type of boiler? - ✔✔A hot water boiler
✔✔Globe valves are used when you need to: - ✔✔Throttle or restrict the flow
✔✔Three types of drafts are: - ✔✔Natural, forced, and induced.
✔✔ For the purpose of rating boiler horsepower for an Engineers License only, how
many square feet of boiler surface shall be equivalent to one boiler horsepower on a
boiler? - ✔✔10 Sq. Ft. Heating Surface
✔✔What is meant by the term "Low Pressure Boiler"? - ✔✔Boilers operating at a steam
or other vapor pressure of 15psig or less, or a hot water or other liquid boiler in which
the pressure does not exceed 160 psig or a temperature of 250 degrees F.
✔✔A person holding a current State of Minnesota Special Engineers License could be
in charge of, or a shift engineer in what size plant(s)? - ✔✔High and Low pressure
boilers not to exceed a total of 50 boiler horsepower, or a shift engineer in a 100
horsepower plant.
✔✔Special Engineer may serve as an apprentice of what size water/liquid or
steam/vapor boiler? - ✔✔In any plant regardless of size under the direct supervision of
a properly licensed engineer.
✔✔The purpose of low water cut out on a steam or hot water boiler is to what? -
✔✔Shut off the burner when a low water condition exists.
✔✔The valve or valves that must relieve all excess pressure on a steam or hot water
boiler are what? - ✔✔Safety valve and/or an ASME approved safety relief valve.
✔✔A Tri indicator could be found on a: - ✔✔Hot water boiler
✔✔A tri indicator would inform the boiler operator of what? - ✔✔The TEMPERATURE of
the water, the PRESSURE of the water in PSIG, and the ALTITUDE of water in feet.
✔✔What is the destructive force in a steam or hot water boiler explosion? - ✔✔The
instant release of energy stored in the water as heat.
, ✔✔An ASME approved safety relieve calve used on a hot water boiler is tested at the
factory on what? - ✔✔Steam first then hot water.
✔✔Some of the things you could find on a steam boiler (or hot water boiler) are what? -
✔✔Low water cut off, safety valve or safety relief valve, pressure gauge.
✔✔What devices would only be found on a steam boiler? - ✔✔Steam pressure gauge,
tricocks, Pressuretrols
✔✔An expansion tank or compression tank would be used in what? - ✔✔Hot water
boiler
✔✔What is the purpose of the expansion tank? - ✔✔To provide for expansion and
contraction of the water volume as its temperature varies.
✔✔On a hot water boiler, what is the purpose of the vent valve? - ✔✔To make sure
there is water inside the boiler and to vent any trapped air.
✔✔If the safety valve or ASME safety relief valve leaks you would do what? - ✔✔Have
the valve repaired or replaced.
✔✔Tri cocks or gauge cocks are sued on a steam boiler to indicate? - ✔✔The true
water level inside the boiler.
✔✔On a steam or hot water boiler, the safety valve or safety relief valve could be tested
by? - ✔✔When the boiler is running lifting the lever on the valve or raising the pressure
until they operate.
✔✔Before starting a steam or hot water boiler you should check for what? - ✔✔Water in
the boiler.
✔✔True or False: Bottom blow down valves are used for both steam and hot water. -
✔✔True
✔✔Safety valves or safety relief valves should be manually tested at least...? -
✔✔Monthly
✔✔The low water cut out is one of the most important electrical/mechanical devices on
your boiler. How often should you test it? - ✔✔Daily
✔✔What device must be located between a hot water boiler and the expansion tank? -
✔✔A shut off valve so the expansion can be isolated and drained during operation of
the boiler.
