Abstract
A method for desulfurizing exhaust gases such as flue gases from steam generators that have been charged with brown coal, in which powdered lime is charged into the furnace and then removed or precipitated from the flowing exhaust gases after a certain reaction time. The dust or particulate matter which has been removed from the flowing exhaust gas stream, and which is at least partially charged with noxious substances along the surfaces thereof, is pulverized and then subjected to dry stream hydration, followed by recycling into the flue gas stream which has been cooled to a lower temperature. During the dry steam treatment, the points of fracture or exposure of the pulverized particulate additive are activated so that Ca(OH).sub.2 formation takes place, which has a high affinity for sulfur dioxide at low temperature. An apparatus for pulverizing and hydrating the particulate matter is also provided.
