What is the primary function of a condensate return system?

The primary function of a condensate return system is to collect and return condensed steam back to the boiler for reuse. In steam systems, steam is generated in the boiler and is utilized for heating, power generation, or other processes. After performing its function, the steam condenses back into water, also known as condensate.

Recycling this condensate is crucial for overall system efficiency. By returning it to the boiler, the system reduces the need to convert additional water into steam, saving both energy and water resources. This process not only helps in efficient water management but also minimizes heat loss, contributing to the system's overall economy and sustainability.

The other options cover functions that are not primary to a condensate return system. Generating additional steam is outside the scope of condensate return systems, which focus on the management of condensed steam. Providing cooling for the boiler system is also not the main role; while cooling might be necessary in some parts of the system, that is not the primary intent of a condensate return system. Lastly, monitoring pressure levels is a crucial operational procedure within the power system but it does not relate to the function of returning condensate to the boiler.
