What is the primary function of a boiler?

The primary function of a boiler is to generate steam efficiently. In various applications, particularly in industrial and commercial settings, steam is a crucial medium for transferring heat and powering equipment. The process involves heating water to its boiling point, allowing it to turn into steam, which can then be utilized for heating processes, driving turbines for electricity generation, or providing energy for various manufacturing operations.

When assessing the efficiency of a boiler, it's important to consider heat transfer and steam generation under specific pressures and temperatures. An efficient boiler maximizes steam output while minimizing fuel consumption and energy loss, making it a critical component in systems that rely on steam for functionality.

While heating water is indeed a part of the boiler’s operation, the core purpose revolves around producing steam that serves various functions beyond just heating. Generating electricity can be an end-use of the steam produced, particularly in power plants, but it is not the primary function of a boiler itself. Storing heat is not applicable to boilers, as they primarily focus on producing steam rather than maintaining heat over time.
