Which of the following best describes the role of a boiler feedwater system?

The role of a boiler feedwater system is primarily to supply water to the boiler. This system is crucial in maintaining the operational efficiency and safety of the boiler. The feedwater system ensures that there is a consistent and adequate supply of water that is pre-treated and prepared to enter the boiler, where it is converted into steam. Proper management of the feedwater is essential for controlling pressure, temperature, and preventing damage to boiler components due to scale or corrosion.

In this context, while heating water for production and cooling condensate are relevant to various aspects of boiler operation, they do not directly address the main function of a feedwater system. Disposal of hot gases pertains to exhaust management rather than the supply of water, which further clarifies why the focus on supplying water to the boiler is the best description of the feedwater system’s role.
