Spray Dryer - an overview ScienceDirect Topics

3.2.2.1 Spray dryer absorber and CFB absorber systems. Spray dryer-based FGD historically has been the most common “dry” FGD technology used in the United States dating back to the early 1980s. However, it is somewhat of a misnomer to call this technology “dry,” as a slaked-lime-based aqueous slurry is actually fed to the spray dryer ...

Spray Dry Scrubber - an overview ScienceDirect Topics

The primary alternative to the forced oxidation WFGD emerged as the spray dryer/absorber (SDA) developed by Joy/Niro and numerous other vendors [46,47]. Spray dry scrubbers were first installed in the early 1980s in the United States [42]. The application of dry scrubbers to large electric utility boilers has been somewhat limited to those ...

Spray Dryer Design

The most important variables in the design of a spray dryer are the evaporation rate and the required particle size distribution of the product. The evaporation rate and the dryer ΔT (inlet air temperature minus the outlet air temperature) dictates the amount of drying air needed, which dictates the sizing and cost of almost all of the system ...
