The Fan Curve / Secondary Heat Exchanger Curve is a component that shapes the airflow or heat exchange path in a boiler or burner system. It may be a curved duct or guide that directs air from the fan or secondary heat exchanger, optimizing combustion and heat transfer. This part is essential for maintaining efficient system performance and is often replaced when damaged or corroded. As a spare part, it helps restore proper airflow dynamics, ensuring that your heating equipment operates safely and effectively. It is a specialized component for technicians familiar with boiler and burner internals.
