More Dry scrubber analysis from Kiewit
See previous articlesfor details but here is more: For the CFBs, a typical approach temperature is 30°F to 40°F, while for the NID a tighter approach of 25°F to 30°F is more common. Because the temperature is still maintained above saturation, reactor materials of construction are typically carbon steel. Type 316 L stainless steel is often used for specialty components such as water injection nozzles and some lime hydrator parts.

Dry scrubber options as listed by Kiewit
In addition to Graff-Wulff, Babcock Turbosorp, and Allied/Lurgi design provide the CFB options. SDA is more widely used but concern about atomizer O &M costs as well as distributing the slurry in droplets which will dry prior to reaching the particulate collector.
