What is the primary purpose of a boiler in a stationary engineering system?

The primary purpose of a boiler in a stationary engineering system is to generate steam for power or heating. Boilers operate by heating water until it transforms into steam, which can then be used to drive turbines for electricity generation or provide heating for buildings and industrial processes. This steam plays a crucial role in many operations, as it can effectively transfer energy and maintain required temperatures for various applications.

Other functions like water storage, filtering, or controlling room temperature do not capture the essence of a boiler's primary role. While systems related to cooling or filtration are essential in overall system efficiency and water treatment, they are not the fundamental purpose of a boiler. The key function of producing steam makes it integral to many engineering and heating systems.
