Abstract
Abstract Humidification apparatus comprising a housing having a flue gas inlet and outlet with a conduit extending therebetween, a circulating air inlet and outlet spaced apart so as to create a circulating air flow zone within the housing, an expansion chamber mounted within the flue gas conduit, a water dispersing medium mounted in and open to the flow zone, a water pipe connected to communicate between the chamber and medium and a water supply system connected to the expansion chamber, whereby, when the flue gas inlet is connected to a source of hot flue gases, water is forced from the expansion chamber to the dispersing medium and is picked up by the circulating air passing through the flow zone.
