What is the term for water supplied to the boiler at the proper temperature and pressure?

The term for water supplied to the boiler at the proper temperature and pressure is "feed water." This water is a crucial component in the steam generation process of a boiler system and is treated to remove impurities that can cause corrosion and scaling. Feed water must meet specific quality standards to ensure the efficient and safe operation of the boiler.

Makeup water refers to water added to replace water lost through steam escape or leaks, while condensate refers to the water that has condensed back from steam after performing work in a heat exchange process. Pure water is a more general term that signifies water free from contaminants but does not specifically relate to the controlled conditions of temperature and pressure required for boiler operation. Each of these terms indicates different types of water in a boiler system but feed water is the term specifically associated with water supplied to the boiler for steam production.
