What is the primary function of a boiler in a steam power plant?
Answer & step-by-step solution
The boiler's primary function is to transfer heat from fuel/heat source to feedwater and convert the water into high-pressure steam for the turbine.
Concept & Reasoning
A boiler includes heat-transfer surfaces such as economizer, evaporator/water walls, superheater and often reheater. It does not generate electricity directly; the turbine-generator does. Pressure rise is mainly established through the feedwater/boiler system, but the core boiler role is steam generation.
How to Solve It in the Exam
Boiler makes steam; turbine makes shaft power; generator makes electricity.
Important Exam Point
Differentiate boiler from feed pump and superheater functions.
Quick Trick
Boiler makes steam; turbine makes shaft power; generator makes electricity.
Common Mistake
Selecting 'increase pressure' as the primary function instead of steam generation.
