US4113840A - Process for the removal of sulfur dioxide

Sulfur dioxide is removed from exhaust flue gases continuously by contact with adsorbent, activated carbon, in aqueous slurry form, preferably in a venturi contactor. The carbon with adsorbed sulfur dioxide is partially dewatered and passed to an oxidation zone in which the sulfur dioxide is converted to sulfur trioxide and absorbed into the aqueous phase to form saleable sulfuric acid.

CLEANING OF FLUE GASES IN THERMAL POWER PLANTS

The CFB technology dry flue gas cleaning is primarily intended for small and medium thermal power plants, which use coal with a high concentration of sulphur as their primary fuel. In comparison to the wet flue gas cleaning process, the CFB technology is relatively favourable, and its scrubber capacity and quality are very competitive.

Hitachi Zosen NOx Flue Gas Treatment Process vol 1 Pilot

Ammonium Sulfate/Bisulfate The presence of sulfur trioxide (SOs) in the flue gas can lead to a reaction with ammonia to form ammonium sulfate and ammonium bisulfate. When burning heavy fuel oil, approximately 2- 4% of the SOX in the flue gas are present as SO3. For coal combustion, S03 accounts for approximately 1 % of the total SOx.

Neundorfer | Optimizing the Performance of Air Pollution

High Air Heater Exit/ESP Inlet Temperatures. The air heater is usually the last piece of equipment before a cold-side ESP. It transfers some heat from the flue gas back into the boiler system to pre-heat combustion air. This significantly reduces the temperature of flue gas heading downstream to the ESP, from about 700F to about 300F.

Coal Drying Improves Performance and Reduces Emissions

The flow rate of flue gas leaving the furnace firing drier coal is lower compared to the wet fuel. Also, the specific heat of the flue gas is lower due to the lower moisture content. The result is reduced thermal energy of the flue gas. Lower flue gas flow rate also results in lower rates of convective heat transfer.

US7585476B2 - Process for controlling the moisture

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.
