What type of fan is designed to operate at higher temperatures compared to a forced draft fan?

The induced draft fan is specifically designed to function at higher temperatures in comparison to a forced draft fan. Induced draft fans operate by removing flue gases or exhaust from combustion processes, making them suitable for applications involving high-temperature environments, such as in boilers or furnaces. This capability allows them to handle the thermal expansion and the corrosive effects that high temperatures and combustion gases can produce.

On the other hand, a forced draft fan is primarily used to introduce air into combustion systems and typically operates at lower temperatures, mainly ensuring adequate oxygen supply for combustion. While other fan types such as exhaust fans and standard ventilation fans may manage airflow, they are not explicitly engineered to handle the same elevated temperatures that an induced draft fan does, making the induced draft fan the ideal choice for high-temperature scenarios.
