Feedwater is defined as the water that is supplied to a boiler to be converted into steam. This water is critical for the operation of a boiler system, as it serves as the primary raw material for steam generation, which is essential for heating or power generation processes. The feedwater may originate from various sources, such as the municipal water supply, treated water systems, or condensate returns from the steam distribution system.

In the context of boiler operations, maintaining the quality of feedwater is important because impurities in the water can lead to scaling, corrosion, and other operational issues that affect the efficiency and safety of the boiler. Proper treatment and testing of feedwater are necessary to ensure that it complies with the specific standards for use in low pressure boilers.

The other choices refer to different types of water or processes that do not align with the definition of feedwater. Water extracted from the atmosphere is associated with atmospheric humidity but is not typically utilized in regularly scheduled boiler operations. Water used for cleaning the boiler pertains to maintenance procedures rather than the core steam generation process. Wastewater from the boiler, often a byproduct of the steam generation process, is not reused directly as feedwater without additional treatment, as it may contain contaminants.
