What are the main components of a boiler system?

The main components of a boiler system are correctly identified as including the boiler itself, the burner, controls, the feedwater system, and the exhaust stack.

The boiler is the central unit where water is heated or converted to steam. The burner provides the necessary fuel and air to create combustion, which generates heat. Controls are essential for managing the operation of the boiler, including maintaining proper temperatures and pressures, and ensuring safe operation. The feedwater system is responsible for supplying water to the boiler, which is crucial to its functioning. Lastly, the exhaust stack allows for the removal of flue gases produced during combustion, ensuring that harmful emissions are vented safely outside the environment.

This comprehensive inclusion of components reflects the complexity of boiler operations and highlights the necessity of each part working together for the efficient and safe functioning of the system.
