ABSTRACT:
A method and system of near saturation gas humidification by mixing a steam and a gas flow is disclosed. The steam is generated with a heating device at a controlled rate from a liquid contained in a vessel near the point of use of the humidified gas. The controlled rate results from a feedback loop that controllably heats the liquid while measuring the steam temperature and maintaining it around a set point. The humidification delivery rate is adjustable by adjusting the temperature set point and/or the gas pressure. Undesirable components from the humidified gas are removed with an in-line filter after its point of generation. Condensation from the humidified gas before its point of use is removed with a drain pipe in combination with a drain valve triggered by a condensation level sensor.
