A mixer for recirculating ash from solid fuel combustion with hydrated lime and water and to feed the mixture into a desulfurization reactor. The mixer includes a housing having a front wall, two outer vertical sidewalls, a rear wall, a top, and a bottom, the top includes a feed chute configured for the entry and addition of product to the mixer, and the front wall includes an opening for the mixture of product to exit. The mixer also includes a rotatable vertical shaft having an impeller, the impeller having a plurality of blades disposed on the vertical shaft in the same horizontal plane and distributed equidistantly about the circumference of the vertical shaft. The mixer also includes a vertical wall disposed within the housing forming a mixing region and a feeding region that is operably connected to the opening of the front wall.

System and method for mixing recirculating combustion ash with hydrated lime and water

A lime hydrator integrated into a flue gas desulfurization system or other industrial system is provided that provides an in-situ variable rate of cured hydrated lime production for a variable supply rate of the in-situ produced cured hydrated lime for use within a flue gas stream as a moistened hydrated lime for a reduction of acid gas present in a flue gas stream. Also provided is a method of using a lime hydrator integrated into a flue gas desulfurization system or other industrial system to provide in-situ a variable production rate of cured hydrated lime for a variable supply rate of the in-situ produced cured hydrated lime for use within a flue gas stream as a moistened hydrated lime for a reduction of acid gas present in a flue gas stream.

Integrated lime hydrator

A method of operating a turbine unit, wherein recirculated exhaust gas is contacted with a cooling and absorption liquid in a packed bed. An exhaust gas treatment system for a turbine unit, wherein an exhaust gas recirculation line comprises a gas cooling and cleaning device having a packed bed for contacting the exhaust gas with a cooling and absorption liquid. A combined cycle power generating system, wherein an exhaust gas recirculation line comprises a gas cooling and cleaning device having a packed bed for contacting the exhaust gas from a gas turbine with a cooling and absorption liquid and wherein water utilized as a cooling medium for condensation of steam originating from a steam turbine, and the cooling and absorption liquid, are passed to a cooling tower.

Preparation of exhaust gas from a gas turbine for exhaust gas recirculation

A method for removing NOfrom flue gas by SCR includes supplying a reagent for the SCR reaction of NOinto the flue gas, then contacting the flue gas with a catalyst. Supplying the reagent includes supplying a less than stoichiometric amount of reagent, and after contacting the flue gas with a catalyst a final NOremoval step is provided.

Method and system for NOremoval

The invention relates to a method for operating a gas turbine system, wherein the gas turbine system includes a compressor, a combustor, a heat recovery steam generator, a scrubber, a direct contact cooler. The method includes introducing the scrubbing fluid discharged from the scrubber into the direct contact cooler, contacting the scrubbing fluid in the direct contact cooler with the exhaust gas discharged from the heat recovery steam generator in order to remove a portion of nitrogen oxide therefrom; feeding the exhaust gas discharged from the direct contact cooler into the compressor. With the technical solution of the present invention, nitrogen oxide in the exhaust gas is reduced to a certain extent by means of used scrubbing fluid from the scrubber. This solution may improve the efficiency in reduction of nitrogen oxide with a simple and feasible manner.

Method of exhaust gas treatment for a gas turbine system and exhaust gas treatment assembly

The combustion and flue gas treatment system includes a furnace for combusting a fuel with an oxidizer generating a flue gas, ducting for the flue gas connected to a NOremoval unit and a SOremoval unit, and a recirculation line for recirculating a part of the flue gas back to the furnace. The SOremoval unit is located upstream of the NOremoval unit with reference to the flue gas flow. The recirculation line is connected to the ducting downstream the SOremoval unit.

A gas cleaning system () for cleaning a carbon dioxide rich flue gas containing sulphur dioxide generated in a boiler () comprises a first gas cleaning device () being operative for removing at least 80% of the sulphur dioxide content of the flue gas generated in the boiler (), thereby generating a partly cleaned carbon dioxide rich flue gas, and a second gas cleaning device (), being separate from the first gas cleaning device () and being operative for receiving at least a portion of the partly cleaned carbon dioxide rich flue gas that passed through the first gas cleaning device (). The second gas cleaning device () is operative for removing at least a portion of the water content of the partly cleaned carbon dioxide rich flue gas by means of cooling the partly cleaned carbon dioxide rich flue gas to condense water there from.

Method and a device for cleaning a carbon dioxide rich flue gas

An apparatus and method to recover heat from and cool flue gases. As shown in FIG., a condenseris provided having two packed beds () and separate condensate loops. The condensate loops are configured such that first packed bedmaximizes heat recovery from flue gasand second packed bedmaximizes cooling of flue gas. Temperature differences between entry flue gasand recovered condensateare minimized while temperatures differences between exit flue gasand return condensateis also minimized.

Condenser and method for heat recovery and cooling

An apparatus and method to clean flue gases. As shown in FIG., a condenseris provided having two packed beds () and two condensate loops. The condensate loops are configured such that anti-corrosive agent () may injected. Corrosives are removed from flue gases as condensate containing anti-corrosive agents passes over the flue gases.
