1. A Grade 1 stationary engineer in Maryland is authorized to:
A) Operate boilers only up to 100 hp
B) Supervise Grade 2 engineers and manage entire plant operations
C) Perform all duties of lower grades and serve as chief engineer in any facility –
CORRECT ANSWER – Grade 1 is the highest Maryland stationary engineer
license, allowing unlimited supervisory authority and plant management.
D) Only inspect boilers, not operate them
2. The maximum allowable accumulation for a power boiler equipped with a
superheater and reheater is:
A) 6% on drum, 10% on superheater
B) 6% on drum, 6% on superheater, and reheater separately – CORRECT
ANSWER – ASME Section I requires all safety valves to limit accumulation to 6%
of MAWP.
C) 10% on all
D) 15% on all
3. A Grade 1 engineer must have held a Grade 2 license for a minimum of:
A) 6 months
B) 2 years – CORRECT ANSWER – Maryland experience requirement for Grade
1 upgrade.
C) 3 years
,D) 5 years
4. The ASME Code Section VIII covers:
A) Power boilers
B) Unfired pressure vessels – CORRECT ANSWER – Grade 1 engineers must
understand related pressure vessel codes.
C) Heating boilers
D) Nuclear components
5. A boiler’s “maximum continuous rating” (MCR) is defined as:
A) Peak load for 1 hour
B) The maximum output sustained over 24 hours without overloading –
CORRECT ANSWER – Basis for nameplate capacity.
C) Minimum load
D) Blowdown rate
6. The primary difference between natural circulation and forced circulation boilers
is:
A) Fuel type
B) Natural uses density difference; forced uses pumps for circulation – CORRECT
ANSWER – Forced circulation allows higher pressures and smaller drums.
C) Water treatment
D) Safety valve type
7. A Grade 1 engineer is responsible for the development and implementation of a
plant’s:
A) Fuel purchasing schedule
, B) Boiler safety program, training, and emergency procedures – CORRECT
ANSWER – Chief engineer responsibility under Maryland law.
C) Building maintenance
D) Payroll
8. The term “once-through boiler” means:
A) Water passes through once, no steam drum – CORRECT ANSWER – Used in
supercritical boilers; no recirculation.
B) Fire passes once
C) Fuel passes once
D) Blowdown once per shift
9. A supercritical boiler operates at pressure above the critical point of water,
which is:
A) 1000 psig
B) 2212 psia (approximately 3208 psig) – CORRECT ANSWER – Above 3208
psig, water and steam have same density; no boiling.
C) 500 psig
D) 150 psig
10. The minimum number of safety valves required on a boiler with over 500
square feet of heating surface is:
A) One
B) Two or more – CORRECT ANSWER – ASME Code requires at least two
safety valves.
C) Three
D) Four
