Abstract:
1. A method of reducing the moisture concentration of flue gas comprising: providing a flue gas comprised of combustion gases, passing the flue gas through a spray tower apparatus having a flue gas inlet and a flue gas outlet, providing a liquid reagent; storing the liquid reagent in a liquid reagent storage means, reducing the temperature of the liquid reagent in the liquid reagent storage means at a temperature below that of the flue gas water vapor dew point at the flue gas inlet, cooling the flue gas by spraying the liquid reagent on the flue gas within the spray tower apparatus; condensing moisture from the flue gas by spraying the liquid reagent on the flue gas within the spray tower apparatus; and recirculating a portion of the flue gas exiting the spray tower apparatus to a burner to facilitate combustion.
