Which component helps maintain proper air flow in boiler systems?

The component that helps maintain proper airflow in boiler systems is the damper. Dampers are devices that regulate the flow of air and gases in a duct or chimney. By adjusting the damper's position, it controls the amount of air entering the combustion chamber, which is crucial for achieving optimal combustion efficiency. Proper airflow is essential as it ensures that there is enough oxygen for the fuel to burn, and it aids in the effective removal of combustion gases. A well-designed damper system allows for flexibility in adjusting airflow to meet varying operational requirements, enhancing the overall performance of the boiler.

While air filters, baffles, and fans play important roles in the overall system, they do not directly regulate airflow in the same way dampers do. Air filters primarily keep out contaminants, baffles can redirect airflow but are not typically adjustable for flow control, and fans assist in moving air but rely on dampers for precise airflow regulation within the system.
