STEAM BOILER QUIZ-II

Why is high-quality steel used to make boilers

• Its cheaper to produce

• It's easier to bend and use in the manufacturing process

• Because boilers are subjected to high stress and heat during operation

• to reduce cost

What forces are a boiler subjected to during operation

• compression

• tension

• shear

• all of the above

It is defined as a component in the plant cycle that consists of a closed vessel that uses the heat produced by the combustion of fuel to efficiently vaporize and convert water into steam at the desired temperature and pressure.

• Steam Drum

• Boiler

• Furnace

• Reheater

________is the transfer of heat through a solid object, or between two objects, as a result of physical contact.

• Conduction

• Convection

• Radiation

It is an extremely high-temperature vapor generated by heating the saturated steam obtained by boiling water.

• Superheated Steam

• Saturated Steam

• Unsaturated Steam

• Vapor

_______ is the transfer of heat within a fluid, that is a liquid or gas. It is caused by a mixing action within a fluid.

• Conduction
