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 spray dryer disperseris described for use in a spray dryer absorption (SDA) systemfor flue gas FG impurity reduction. As such, the spray dryer disperserdisperses absorbent liquid or reagent slurry droplets into contact with a hot flue gas FG stream containing gaseous impurities to produce a flue gas FG stream of reduced impurity content and dry powder end products EP. The spray dryer disperseris useful in larger capacity SDA vesselsof approximately 12 to 22 meters in diameter or larger, to avoid dispersershroudscale deposits, to avoid reagent slurry spray cloud suppression, to avoid vesselwallscale deposits and to achieve increased droplet rotational momentum for increased droplet flue gas FG penetration for efficient impurity reduction.
