Dry sorbent reactivation process

摘要

Apparatus and process to achieve improved performance with a dry scrubbing flue gas desulfurization (FGD) system. The process consists of injecting sorbent slurry into flue gas from fossil fuel combustion, cooling the flue gas containing the injected slurry and collecting the slurry solids, reaction products, and fly ash in a filter. The apparatus comprises means for cooling the flue gas between the slurry injecting means and the filter.
