ABSTRACT:
A method and an apparatus for the denitrification and desulfurization of hot waste gases, particularly from furnaces. A crude gas flow is initially conducted through a denitrification plant and through the endothermic part of a heat-utilizing plant. Subsequently, the flow is conducted into a desulfurization plant. The purified gas flow discharged from the desulfurization plant is conducted through the exothermic part of the heat-utilizing plant and is subsequently transferred to ambient. By means of a cooling trap, a portion of the heat contained in the crude gas flow before the contact with the heat-utilizing plant is removed while precipitating sulfuric acid in the form of vapor, and this heat is then added to the purified gas flow before the contact thereof with the heat-utilizing plant. Another cooling trap connected to an external cooling unit may be arranged in the crude gas flow between the cooling trap arranged in the crude gas flow in front of the heat-utilizing plant and the endothermic part of the heat-utilizing plant.
