摘要： The present invention is related to a system for removal of moisture and contaminants from recirculated flue gas. The system includes a spray tower for spraying the flue gas with a liquid reagent to remove contaminants from the flue gas. A heat exchanger, integrally connected to the spray tower, cools the liquid reagent before the reagent is sprayed onto the flue gas stream. Cooled liquid reagent improves the condensation of the water vapor in the flue gas during the spraying process and provides a lower moisture content flue gas exiting the system. Combustion process efficiency improves as flue gas redirected to the burner for combustion contains.

摘要： The invention is related to a system for removal of moisture and contaminants from recirculated flue gas which is used for combustion in fossil fuel power plants. The system includes a spray tower having an inlet at one end of the housing and an outlet at an opposite end of the housing for channeling the flue gas into and out of the housing. Sprayers are located in the housing for spraying the flue gas with a liquid reagent to remove contaminants, including SO2, from the flue gas. A heat exchanger is integrally connected to the housing. The heat exchanger cools the liquid reagent before the reagent is sprayed onto the flue gas stream. The sprayers quench the flue gas stream with the cooled liquid reagent. The cooling of the liquid reagent to a temperature below the flue gas water vapor dew point improves the condensation of the water vapor in the flue gas during the spraying process. The flue gas exits the system with a lower moisture content and is redirected to burner for combustion. As a result, the efficiency the combustion process will improve with less moisture in the flue gas.

摘要： A method and system for dehumidifying flue gas from a flue gas generating. Water is supplied from a cooling tower to a heat exchanger in the liquid in the lower end of a wet flue gas processor for cooling the liquid in the lower end of the wet flue gas processor to condense water from the flue gas into the liquid in the wet flue gas processor. Returning water from the heat exchanger to the cooling tower cools the water and the liquid with the condensed water is supplied from the wet flue gas processor to the cooling tower as make-up water for the cooling tower to reduce or eliminate the need for fresh make-up water.

摘要： An in-situ forced oxidation wet flue gas desulfurization apparatus, method and arrangement for utilization with oxy-fuel combustion power plants. The apparatus is a tower-like structure having a flue gas scrubbing zone and a reaction zone located subjacent to the gas scrubbing zone. A sulfur oxide absorbing liquid slurry is supplied to the gas scrubbing zone to react with and scrub the sulfur oxides from the flue gas. The partially reacted liquid slurry reagent and the scrubbed products drain into the reaction zone, rising to a set level. Oxidation air is introduced into the liquid slurry in the reaction zone to force the in-situ oxidation of sulfur compounds collected in the reaction zone. A wall separates and communicates the gas scrubbing zone and the reaction zone, the wall prevents the oxidation air from entering the gas scrubbing zone and extends into the liquid slurry below a nominal depth required to establish and maintain a liquid slurry seal thereby substantially precluding the leakage of flue gas into the reaction zone while allowing the partially reacted liquid slurry reagent and scrubbed products to drain into the reaction zone.

摘要： A tri-sector regenerative oxidant preheater apparatus, method and arrangement for utilization with oxy-fired pulverized coal combustion power plants. The preheater includes a stationary housing and a rotor rotatably mounted in the housing. Sector plates are located at the axial ends of the rotor and divide the preheater into a flue gas sector, two primary oxidant sectors, and a secondary oxidant sector interposed between the two primary oxidant sectors. A primary oxidant fan is located downstream of the preheater to create a negative environment in the primary oxidant sectors. During operation of the preheater, the environments of the two primary oxidant sectors and the flue gas sector are at about the same negative pressure, and thus there is very limited leakage between the oxidant side and the flue gas side of the preheater. The environment of the secondary oxidant sector is at a positive pressure and leakage to the negative environment of the primary oxidant sectors will be that of secondary oxidant to primary oxidant with no loss secondary oxidant to the gas side of the preheater.
