Preview Questions Boiler Operator | Role Specific Skill

Question 1: How does overfiring a boiler by increasing fuel flow impact the system?

Which action should you take?

Choose only one option

It increases fuel consumption but can lead to overheating

It improves steam output and system efficiency

It leads to lower emissions

It stabilizes the water level

Question 2: What does thermal shock in a boiler refer to, and how can it be avoided?

Which action should you take?

Choose only one option

It refers to corrosion damage caused by overheating, which can be avoided by adding corrosion inhibitors.

It occurs when the boiler pressure fluctuates too rapidly, which can be avoided by controlling the draft fan speed.

It is the unexpected increase in steam production, which can be prevented by monitoring water levels.

Thermal shock occurs when there is a sudden temperature change in the boiler, which can be avoided by gradual heating.

Question 3: In a typical fire-tube boiler, which factor affects the efficiency of heat transfer most?

Which action should you take?

Choose only one option

Tube surface area

Rate of combustion

Pressure drop in the flue gas system

Water temperature

Question 4: When managing fuel storage tanks, what is the most critical factor in maintaining fuel quality for boiler operation?

Which action should you take?

Choose only one option

Maintaining constant temperature within the tank to prevent freezing.

Minimizing tank exposure to sunlight to reduce degradation of the fuel.

Periodic fuel sampling for moisture content analysis.

Regular tank cleaning to prevent sludge buildup and contamination.

Question 5: What could be the consequence of overheating steam in a boiler?

Which action should you take?

Choose only one option

Damage to steam turbines and equipment

Reduced water usage

Increased boiler efficiency

Increased fuel efficiency

Question 6: What is a common cause of burner flame instability and how is it resolved?

Which action should you take?

Choose only one option

Incorrect air-to-fuel ratio; adjust combustion settings

Low feedwater pressure; increase feedwater supply

Insufficient water temperature; increase the heater output

Improper fuel quality; switch to cleaner fuel
