Dual-stage humidifier methods and systems
A humidifier includes a burner for burning fuel within a water tank for generating steam, a primary heat exchanger within the water tank for transferring heat from products of combustion of the fuel to the water within the water tank, and a secondary heat exchanger. The secondary heat exchanger includes a combusted gas section for receiving the cooled products of combustion from the primary heat exchanger and a water section for transferring additional heat from the cooled products of combustion to water flowing within the secondary heat exchanger. The humidifier further includes a secondary fill valve which is pulsed to provide cool water for transferring additional heat from the cooled products of combustion to water flowing within the secondary heat exchanger. The water from a primary fill valve is fed directly into the water tank. An outlet of the secondary heat exchanger is fed directly into the water tank.
