VERFAHREN UND ANLAGE ZUR REINIGUNG DER ABGASE VON FEUERUNGSANLAGEN

摘要

A process for cleaning exhaust gases from furnace installations, for subsequent connection in order to remove the sulphur while selectively reducing the nitrogen monoxide by the introduction of chemical compounds and the use of catalytically operating surfaces in order to accelerate and/or initiate the reaction with heating of the exhaust gases at the temperature required for reduction. This is achieved by the fact that at least a partial current of the chemical compound (S) or of this or these compounds (S) mixed with a carrier gas is fed into the exhaust gases before or during heat transfer from the exhaust gases released by the reduction of nitrogen monoxide to the exhaust gases which are still to be subjected to reduction.
