ACTUAL Exam Questions and CORRECT
Answers
High-pressure boiler fittings - CORRECT ANSWER - Various fittings can be attached,
including threaded, certified welds, and flanges.
Relieving capacity test - CORRECT ANSWER - Determines the relieving capacity of
safety valves, with options like hydrostatic, accumulation, Orsat, and evaporation tests.
Heat recovery from flue gases - CORRECT ANSWER - Heat recovery can be achieved
using devices like flash tanks, open feedwater heaters, and economizers.
Feed water heating source - CORRECT ANSWER - Feed water is typically heated using
waste or extracted steam, not commercial hot water heaters or superheaters.
Boiler capacity - CORRECT ANSWER - The maximum pounds of steam per hour a boiler
can produce, not to be confused with steaming rate, heating surface, or water tube.
Steam condenser reservoir - CORRECT ANSWER - The reservoir in a steam condenser is
known as a hot well, not surge tank, flash tank, or vacuum.
Boiler inspection - main steam valves - CORRECT ANSWER - Main steam valves are
typically closed, locked, and tagged during boiler inspection.
Boiler draft - CORRECT ANSWER - Boiler draft is the difference in pressure between
two points, not gas flow, water flow, or wind.
Pressure gauges on boilers - CORRECT ANSWER - Boilers are required to have pressure
gauges, with options like 1, 2, or 1 for low pressure and 2 for high pressure.
, Feed water pump source - CORRECT ANSWER - Feed water pumps typically take water
from sources like hotwells, open feedwater heaters, or flash tanks, not the boiler.
Causes of high vibrations in feed water pumps - CORRECT ANSWER - High vibrations
in feed water pumps could be caused by factors like high pressure in the DA tank, not cold or hot
feed water.
Best pump for handling dirty water - CORRECT ANSWER - Positive displacement pumps
are best for handling dirty water, not chemical, centrifugal, or gear pumps.
Components of a centrifugal pump - CORRECT ANSWER - Parts of a centrifugal pump
include the volute, impeller, and vanes, not piston rings.
Purpose of check valves on feedwater pumps - CORRECT ANSWER - Check valves on
multiple feedwater pumps help prevent backflow, not for quick start-up, efficiency, or clockwise
prevention.
Starting dynamic displacement pumps - CORRECT ANSWER - Dynamic displacement
pumps should not be started with the discharge valve closed or throttled.
Lubricating oil pumps - CORRECT ANSWER - Lubricating oil pumps are typically rotary,
not centrifugal, dynamic displacement, or a waste of money.
Differences between centrifugal and reciprocating pumps - CORRECT ANSWER -
Centrifugal pumps differ from reciprocating pumps in that they are not positive displacement,
dynamic displacement, steam-driven, or belt-driven.
Temperature restrictions for water entering the sewer - CORRECT ANSWER - Most codes
restrict the temperature of water entering the sewer to a maximum of 140°F, not 115°F, 165°F, or
212°F.
