Abstract: A method for separating carbon dioxide from a flue gas of a fossil fuel-operated power plant is provided. In the method, a fossil fuel is initially burned in a combustion process, wherein a hot waste gas containing carbon dioxide is produced. In a next process step, waste gas containing carbon dioxide is brought into contact with an absorption medium in an absorption process, wherein carbon dioxide is absorbed by the absorption medium, thus forming a charged absorption medium. Next, gaseous carbon dioxide is thermally expelled from the charged absorption medium in a desorption process. For this purpose, a vapor is supplied to the desorption process, the vapor is injected into the charged absorption medium, wherein the condensation heat released by the condensation of the vapor is transferred to the charged absorption medium, and the partial pressure of the carbon dioxide is simultaneously reduced in the desorption unit.

Abstract: The present invention provides improved boiler assemblies (10) with enhanced pollution abatement properties through injection and recycling of particulate sorbent materials including sodium bicarbonate, trona, and mixtures thereof. The assemblies (10) include a boiler (12), economizer (14), air heater (15), and recirculation reactor (16). Fresh sorbent material is introduced via assembly (60) into the boiler assembly (10) at one or more injection locations, and serves to sorb NOx, SOx, and other pollutants in the flue gas. The flue gas and entrained sorbent material then pass through reactor (16) for separation of sorbent, which is then recycled for injection back into the assembly (10) upstream of reactor (16).The present invention can also be used in industrial applications where the same emissions are generated and are needed to be controlled. Examples of such applications are Cement and Lime Kilns.

Abstract: An apparatus and method for achieving increased NOx removal efficiency from an emissions control portion of a fossil fuel fired boiler while controlling ammonia slip provides excess levels of ammonia above those levels conventionally employed in SCR and/or SNCR applications. The apparatus and methods comprise, in part, use of a NOx reduction system comprising at least one selective catalytic reduction system which receives ammonia in higher amounts than conventional practice from an upstream ammonia injection point, and an ammonia reduction system positioned downstream of one or more ammonia injection points and the NOx reduction system. The excess ammonia achieves increased NOx removal, while the ammonia reduction system contains at least one ammonia destruction catalyst which permits the NOx reduction system to be operated at an increased NOx removal efficiency without a corresponding increase in ammonia slip.

Abstract: A method for positioning superheaters (2, 3, 4, 5) in biomass burning steam generators, and a steam generator. The steam generator comprises a combustion chamber (1), a flue gas duct (6), a steam circuit (7), and the superheaters (2, 3, 4, 5) positioned for minimizing corrosion at a high temperature. The steam generator is fitted with at least two superheaters (2, 3, 4, 5), whose positioning in the flue gas duct (6) and serial arrangement in the steam circuit (7) are effected in such a way that the superheater's or superheaters' heat transfer surface has its surface temperature remaining below the melting point of KOH, 406null C. (corresponds to a steam temperature of about 350-380null C.) down to the point in the flue gas duct (6), at which the flue gases' temperature has fallen to 750null C. While the flue gases are within the range of less than 750null C., the final superheating is effected to a higher temperature without significantly increasing the contamination and corrosion hazard for superheater surfaces.
