In addition, excess heat from the flue-gas heat exchangers can be utilized under certain load conditions for

In contrast to the regenerative heat exchanger, no flue-gas leakage takes place between the gas streams in the ECOGAVO system since the exchangers are located separately.This offers advantages in that the heat exchangers can be optimally arranged to suit local conditions. By mounting the exchangers in the immediate vicinity of the FGD plant, corrosion-protected ducts are reduced to a minimum.

The clean-gas reheater is designed in two stages. The clean-gas is dried in the first stage and in the second stage reheated to the required stack outlet temperature.

ECOGAVO, an indirect leakage free heat displacement system around flue-gas desulfurization (FGD) plant, enable flue-gas cooling to below the acid dew point by making use of G-Flon all-plastic heat exchangers, The heat content recovered is used for the reheating of the water vapor saturated clean-gas exiting the scrubber with water being used as heat transfer medium. Reheating of the clean-gas is necessary to protect downstream equipment from corrosion, or attaining a prescribed stack outlet temperature.
