Maryland Stationary Engineer Exam Review 2026 | Verified
Q&A | Graded A+
1. Describe the role of the vent pipe and stack in boiler operation.
The vent pipe and stack facilitate the safe expulsion of combustion
gases from the boiler to the atmosphere.
The vent pipe and stack control the fuel supply to the burner.
The vent pipe and stack regulate the water level in the boiler.
The vent pipe and stack monitor the temperature of the boiler water.
2. If a water tube boiler is experiencing issues with sediment buildup, which
component would you inspect to address this problem?
Mud drum
Safety valve
Feedwater pump
Steam drum
3. What does ASME stand for in the context of boiler operation?
American Society of Mechanical Engineers
American Society of Mechanical Equipment
American Society of Mechanical Energy
American Society of Manufacturing Engineers
4. Why is it important to have a check valve on the feedwater piping going into
a boiler?
, To prevent the boiler from draining through the feedwater line when
the feedwater pump is down
If you have the ability to isolate the feedwater via an isolation valve
you do not need a check valve
It is not important, as long as each boiler feedwater pump is equipped
with a check valve to prevent the water from flowing backwards into
the deaerator
You only need a check valve if you have more than one boiler being
fed from a single set of feedwater pumps
5. If a stationary engineer identifies a malfunctioning safety valve during routine
maintenance, what action should they take based on their licensing
authority?
They should replace the safety valve.
They should report the issue but not take action.
They should ignore the issue if it seems minor.
They should consult a supervisor before taking any action.
6. If a stationary engineer finds lawn maintenance equipment stored in a boiler
room, what action should they take?
Report the equipment to the maintenance supervisor for further
action.
Remove the equipment and ensure the boiler room is clear of
storage items.
Leave the equipment as it is not a safety concern.
Use the equipment for maintenance tasks in the boiler room.
,7. What are the two primary components of boiler vents?
Vent pipe and stack
Boiler drum and water column
Pressure gauge and safety valve
Burner and combustion chamber
8. What does a safety factor of 6 indicate in boiler operation?
It refers to the number of safety devices installed.
It is the maximum temperature the boiler can reach.
It indicates the boiler's efficiency rating.
It indicates that the boiler can handle six times the maximum
expected load.
9. If a candidate has extensive experience operating portable boilers but lacks
experience with stationary boilers, what steps should they take to qualify for
a Stationary Engineer's License?
Seek additional training or apprenticeship in stationary boiler
operations.
Attend a seminar on boiler safety.
Focus on gaining more portable boiler experience.
Apply for the license based on portable boiler experience.
10. What are the positions typically found on a boiler code and review licensing
board?
Members include only engineers and inspectors.
Members include only government officials.
, Members include engineers, inspectors, and industry
representatives.
Members include only industry representatives.
11. Which types of boiler are almost all large boilers?
Water-tube boilers
Fire-tube boilers
Gas-tube boilers
Cylinder boilers
12. What is the typical duration before a boiler license expires?
Every two years
Every ten years
Every five years
Every year
13. What is the primary purpose of water walls in water tube boilers?
To filter impurities from the water.
To absorb heat and provide a surface for steam generation.
To support the boiler structure.
To regulate water flow within the boiler.
14. What is one reason that can lead to the suspension of a stationary engineer's
license?
Failure to maintain equipment
