Preview Questions Boiler Operator | Role Specific Skill

Question 1: What is the purpose of a flame safeguard system in a boiler?

Which action should you take?

Choose only one option

To increase combustion efficiency

To control the flow of fuel

To monitor steam pressure

To prevent combustion-related explosions

Question 2: Why is it important to maintain a correct air-fuel ratio in a boiler combustion process?

Which action should you take?

Choose only one option

To reduce water usage by lowering the steam production rate.

To maintain the boiler's pressure at an optimal level.

To ensure complete combustion, maximizing energy efficiency and minimizing emissions.

Question 3: In a steam boiler, how can the water level be controlled to prevent damage to the boiler?

Which action should you take?

Choose only one option

By increasing the feedwater temperature

By adjusting the fuel-to-water ratio

By using a water level control system and alarms

By manually monitoring the sight glass

Question 4: What is the significance of flue gas recirculation (FGR) in modern boilers?

Which action should you take?

Choose only one option

To lower the water feed temperature

To reduce NOx emissions

To cool down the boiler combustion chamber

To increase combustion efficiency

Question 5: What is the minimum distance a pressure relief valve should be located from the boiler to ensure safety during overpressure conditions?

Which action should you take?

Choose only one option

20 feet

30 feet

10 feet

40 feet

Question 6: How can fuel variability in biomass boilers be effectively managed to ensure continuous and stable boiler operation?

Which action should you take?

Choose only one option

By monitoring and adjusting steam flow based on fuel quality changes.

By increasing boiler pressure to stabilize output during fuel variability.

By adjusting air-fuel ratios and regularly cleaning the combustion chamber to adapt to fuel changes.

By optimizing fuel storage to minimize variability across batches.
