Question 1
In a fire-tube boiler, the hot combustion gases pass through tubes that are surrounded by water.
Which of the following is a characteristic advantage of this design?
A. Higher pressure capacity than water-tube boilers
B. Rapid steam generation and response to load changes
C. Slower response to load changes but simpler construction and lower maintenance
[CORRECT]
D. Ability to handle superheated steam at very high temperatures
Correct Answer: C
Rationale: Fire-tube boilers (HRT, Scotch marine, vertical) have water surrounding the tubes
containing hot gases. Advantages include simpler construction, lower initial cost, and easier
maintenance. However, they have slower response to load changes due to large water volume,
and are generally limited to lower pressures (<350 psi) and saturated steam. Water-tube boilers
(A, B advantages) handle higher pressures and rapid load changes. Fire-tube boilers are not
suitable for high-temperature superheat (D).
Question 2
According to the 2025 ASME Boiler and Pressure Vessel Code, which section governs the
construction of power boilers?
A. Section IV - Rules for Construction of Heating Boilers
B. Section I - Rules for Construction of Power Boilers [CORRECT]
C. Section VIII - Rules for Construction of Pressure Vessels
D. Section IX - Welding and Brazing Qualifications
Correct Answer: B
Rationale: ASME BPVC Section I specifically covers Power Boilers, which generate steam for
power generation or process use above 15 psi. Section IV (A) covers Heating Boilers (low
,pressure steam or hot water boilers for space heating). Section VIII (C) covers unfired pressure
vessels. Section IX (D) covers welding qualifications. The 2025 edition continues these
distinctions with updated materials and design rules.
Question 3
One boiler horsepower is defined as the ability to evaporate:
A. 34.5 pounds of water per hour from and at 212°F [CORRECT]
B. 33,475 BTU per hour
C. 10 square feet of heating surface
D. 100 pounds of steam per hour at 100 psi
Correct Answer: A
Rationale: The standard definition of boiler horsepower (BHP) is 34.5 lbs/hr of water evaporated
from and at 212°F (100°C) into dry saturated steam at 212°F. This equals approximately 33,475
BTU/hr (B is close but not the definition). Heating surface (C) is related but not the definition.
Option D is incorrect.
Question 4
A water-tube boiler design where the steam and water drums are arranged longitudinally with
bent tubes connecting them is characteristic of:
A. Horizontal Return Tubular (HRT) boiler
B. D-type boiler
C. A-type boiler
D. O-type boiler [CORRECT]
Correct Answer: D
Rationale: The O-type boiler has two parallel drums (steam and water) arranged longitudinally
with bent tubes forming an "O" shape between them. D-type (B) has one drum above the furnace
with straight tubes. A-type (C) has a single drum with bent tubes forming an "A" shape. HRT (A)
is a fire-tube boiler.
Question 5
The 2025 ASME BPVC Section I specifies that power boilers must have a factor of safety of at
least:
A. 2:1
,B. 3.5:1
C. 5:1 [CORRECT]
D. 10:1
Correct Answer: C
Rationale: ASME Section I requires a minimum factor of safety of 5:1 for power boilers based
on ultimate tensile strength. This ensures adequate margin between operating pressure and
material failure. The 2025 edition maintains this requirement with updated material
specifications in Section II.
Question 6
Which boiler type is most commonly used in marine applications due to its compact size and
high efficiency?
A. Horizontal Return Tubular (HRT)
B. Scotch marine boiler [CORRECT]
C. Stirling boiler
D. Babcock and Wilcox boiler
Correct Answer: B
Rationale: The Scotch marine boiler is a fire-tube boiler with a cylindrical shell containing
furnace tubes and combustion gas tubes. Its compact, self-contained design makes it ideal for
marine applications where space is limited. HRT (A) is older, larger. Stirling (C) and B&W (D)
are water-tube boilers used in stationary applications.
Question 7
Cast iron sectional boilers are typically limited to:
A. High pressure power generation
B. Low pressure heating applications [CORRECT]
C. Superheated steam production
D. Marine propulsion
Correct Answer: B
Rationale: Cast iron sectional boilers are used for low pressure hot water or steam heating
(typically <15 psi steam or 160 psi water). Cast iron is brittle and cannot withstand high
, pressures or thermal shock. They are not suitable for power generation (A), superheated steam
(C), or marine use (D).
Question 8
The heating surface of a boiler is defined as:
A. The total surface area of the boiler building
B. The surface exposed to hot gases on one side and water/steam on the other [CORRECT]
C. Only the firebox surface area
D. The surface area of the steam drum only
Correct Answer: B
Rationale: Heating surface is the area where heat transfer occurs—surface exposed to
combustion gases on one side and water/steam on the other. This includes tube surfaces, firebox
sheets, and furnace walls. Options A, C, and D are incomplete or incorrect definitions.
Question 9
In the 2025 ASME BPVC, Section VIII Division 1 has been reorganized to:
A. Eliminate all pressure vessel requirements
B. Consolidate vessel-specific requirements into new Part D [CORRECT]
C. Merge with Section I completely
D. Remove all welding requirements
Correct Answer: B
Rationale: The 2025 ASME BPVC Section VIII Division 1 introduces Part D, which
consolidates rules for special vessel types (heat exchangers, jacketed vessels, non-circular
vessels) previously scattered across appendices. This is part of the multi-year "Section VIII
Reorganization Project" to improve clarity and usability.
Question 10
Electric boilers are particularly advantageous when:
A. High pressure steam is required (>1500 psi)
B. Fuel combustion byproducts must be eliminated [CORRECT]
C. Very large steam capacity is needed (>500,000 lbs/hr)
D. Field erection is required for large units
