1.
A boiler operator notices rapidly dropping water level while steam demand remains high. What is the
most likely risk?
, Page 3 of 112
A. Improved combustion efficiency
B. Boiler dry firing and tube damage
C. Reduced pressure stability
D. Increased fuel economy
Answer: B
Rationale: Low water can expose tubes and cause overheating damage.
2.
A First Class operator ignores a low-water cutoff alarm. What is the potential consequence?
A. Improved system stability
B. Catastrophic boiler failure
C. Increased efficiency
D. Reduced steam pressure fluctuation
Answer: B
Rationale: Low-water cutoffs are critical safety devices.
3.
, Page 4 of 112
A boiler shows excessive scaling inside tubes. What is the primary cause?
A. Excess oxygen in fuel
B. Poor water treatment
C. Excess steam pressure
D. High combustion efficiency
Answer: B
Rationale: Hard water leads to scale formation.
4.
A boiler operator increases fuel flow without adjusting air supply. What condition occurs?
A. Complete combustion
B. Incomplete combustion
C. Increased efficiency
D. Reduced emissions
Answer: B
Rationale: Incorrect air-fuel ratio causes incomplete combustion.
