Boiler Operation and Safety Quiz

A steam turbine boiler is not a type of boiler, but a type of steam engine that uses steam turbines to generate electricity.

The primary function of a safety valve in a boiler is to release excess steam pressure to prevent the boiler from exploding.

Steam pressure is not a factor affecting boiler efficiency, as boiler efficiency is primarily influenced by factors such as fuel quality, excess air, and boiler design.

Boiler scaling refers to the formation of impurities such as calcium carbonate and magnesium silicate in boiler water, which can reduce efficiency and cause damage.

A safety precaution when operating a boiler is to regularly inspect and maintain the boiler, ensuring it is in good working condition and safe to operate.

A boiler water level gauge is used to indicate the level of water inside the boiler, ensuring it is within safe operating limits.

Sodium sulfite is commonly used as a boiler water treatment chemical to prevent scale formation by reacting with dissolved oxygen.

Blowdown in a boiler is the process of removing impurities and sludge from the boiler to maintain efficiency and prevent corrosion.

Carryover in boiler operation refers to the contamination of steam with boiler water droplets, which can lead to damage to turbine blades and other components.

Priming in boiler operation refers to the sudden rise in water level causing excessive steam production, which can lead to water hammer and other issues.

A water hammer in boiler operation is a loud banging noise caused by steam condensing in water-filled pipes, often due to priming or carryover.

The pH level of boiler water is significant in boiler operation as it affects boiler efficiency, corrosion rates, and the effectiveness of water treatment chemicals.

Operating above the critical pressure and temperature of water in a supercritical boiler allows for higher steam generation efficiency.

The primary function of a deaerator in a boiler system is to remove dissolved gases from feedwater, which can cause corrosion and reduce efficiency.

A fusible plug in a boiler is designed to melt and release steam in the event of excessive pressure, helping to prevent a boiler explosion.
