First class Boiler Attendant Interview Questions and Answers

There are several types of valves used in boilers, including safety valves, globe valves, gate valves, and check valves.

• Safety valves are used to release excess pressure in the boiler.

• Globe valves are used to regulate the flow of water or steam.

• Gate valves are used to control the flow of water or steam.

• Check valves are used to prevent backflow of water or steam.

• Other types of valves used in boilers include ball valves, butterfly valves, and diaphragm valves.

Feed pump is used to supply water to the boiler. Safety valves are used to release excess pressure from the boiler.

• Feed pump is driven by a motor or steam turbine.

• It pumps water from the feed water tank to the boiler.

• The pump is controlled by a level controller in the boiler.

• Safety valves are installed to prevent the boiler from exploding due to excess pressure.

• They are set to open at a specific pressure and release steam to the atmosphere.

• Regular maintenance and testing of s...read more

Boiler in high temperature vapours can lead to increased pressure and potential safety hazards.

• High temperature vapours in a boiler can cause the pressure to rise significantly.

• This can lead to potential safety hazards such as explosions or leaks.

• Proper monitoring and maintenance of the boiler is crucial to prevent accidents.

• Examples of safety measures include regular inspections, proper ventilation, and emergency shutdown procedures.

Safety valve is a device used to release excess pressure in a system to prevent damage or explosion.

• Safety valve is a type of pressure relief valve.

• It is designed to open automatically when the pressure exceeds the set limit.

• It releases excess pressure to prevent damage or explosion.

• It is a critical component in boilers and other pressure vessels.

• Regular maintenance and testing is necessary to ensure proper functioning.
