The fan power and the intake air temperature have anything

Fan in operation if other conditions remain unchanged, when inlet air temperature changes will vary by medium volume flow fan so that power consumption also changed. Such as running in the pot exhaust gas temperature rises, the fan through the flue gas volume increases, resulting in increased power consumption. If the temperature is high to a certain extent, you can not increase the volume of traffic through the fan, and the mass flow and meet needs, it will limit the boiler output.
