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

The flue gas treatment system () comprises a reactor (), a pre-separator () downstream of the reactor (), a separator () such as a fabric filter downstream of the pre-separator (), a humidifier () downstream of the separator (), a supply () of a pure fresh reagent into the flue gas (FG) downstream of the pre-separator () and upstream of or at the separator ().

Flue gas treatment system and method

An air quality control system (AQCS)useful for treating flue gas FG, such as flue gas FG produced by a fossil fuel fired boileris described. The AQCSis equipped with a dust separator. The dust separatoris useful under relatively high dust load conditions downstream from a dry scrubber reactorwith limited equipment wear and limited space requirements. As such, the dust separator captures particulate matter with a dust trap that intercepts the flow of particulate matter for collection of the particulate matter in a hopper.
