What is the purpose of a feedwater system in a boiler?

The purpose of a feedwater system in a boiler is to supply water to the boiler. This system is crucial for maintaining the proper water level within the boiler, which is necessary for safe and efficient operation. The feedwater is treated and conditioned before entering the boiler to prevent corrosion and scaling, ensuring that the system operates smoothly and efficiently. By continuously providing water, the feedwater system supports the generation of steam, which is critical for the various processes that utilize steam for heating or power generation.

In contrast, other options address different functions or components unrelated to the specific purpose of a feedwater system. For example, removing waste pertains to the boiler's waste management rather than its water supply. Cooling steam relates to steam condensation or heat exchange systems, and measuring steam output involves monitoring systems that do not directly relate to the feedwater supply.
