Abstract
Method for the removal of nitrogen from the exhausts of burners after they are cleaned of dust or sulfur, in which the nitrogen-bearing exhaust gases are reheated by the transfer of heat from the denitrogenated exhaust gases in a regenerative heat exchanger. Before they are finally heated to the temperature level of the reduction reaction, the nitrogen-bearing exhaust gases, and, after their reduction, the denitrogenated exhaust gases, are passed countercurrently to one another in a cyclical alternation, through heat exchanging storage masses in an additional catalytic converter serving as the main converter, whose surfaces are provided with catalytically active compounds.
