The SaveEnergy devaporiser prevents the formation of vapours when the flue gas is discharged into the atmosphere. In this process, the flue gas is directed through a cross-flow heat exchanger. The flue gas is further condensed in this cross-flow heat exchanger. The heat from the flue gas is discharged into the devaporised air. Devaporised air is ambient air that is directed through the cross-flow heat exchanger by axial fans.
The two gases (flue gas and devaporised air) are mixed together. When this mixed gas is discharged into the atmosphere, the saturated vapour line is not undershot. This means that no visual vapours can be seen downstream of the SaveEnergy devaporiser.
