Abstract
A system for providing humidified air includes a tank containing water and one or more heat exchanger tubes mounted in the tank. The system includes a burner assembly positioned to supply heat to the heat exchanger tubes. The system includes an induction fan for inducing combustion gases from the burner assembly through the heat exchanger tubes. Heat from the burner assembly in the heat exchanger tubes generates steam in the tank. The system includes a steam dispersion apparatus connected to the tank for humidifying air with the steam and a means for measuring humidity in a target location. The system also includes a controller for controlling one or both of the fuel supply to the burner assembly or the induction fan in response to the measured humidity in the target location.
