Abstract: The present invention relates to a system (1) and method (100) for drying a residual product (12) from a foodstuff production process, the residual product containing between 20-50% dry substance. The method comprises the steps of producing a main foodstuff product (4) in the foodstuff production process (2); receiving the residual product continuously from the foodstuff production process; supplying the residual product to a mixer (30); supplying the mixed product (31) to a fluidized bed (40); supplying heated air (57) of between 60-150 degrees C. to the fluidized bed; drying the mixed product in the fluidized bed using the supplied heated air by shaking the mixed product; cooling the dried product; and extracting the dried product (42) from the fluidized bed, wherein a portion (62) of the dried product is supplied to the mixer to be mixed with received residual product (12).

Abstract: 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.

Abstract: The flue gas treatment system (1) comprises a reactor (2), a pre-separator (3) downstream of the reactor (2), a separator (4) such as a fabric filter downstream of the pre-separator (3), a humidifier (5) downstream of the separator (4), a supply (7) of a pure fresh reagent into the flue gas (FG) downstream of the pre-separator (3) and upstream of or at the separator (4).

Abstract: An air quality control system (AQCS) 14 useful for treating flue gas FG, such as flue gas FG produced by a fossil fuel fired boiler 12 is described. The AQCS 14 is equipped with a dust separator 37. The dust separator 37 is useful under relatively high dust load conditions downstream from a dry scrubber reactor 36 with 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.
