PROCESS AND INSTALLATION FOR DENITRIFYING FURNACE FLUE GASES

摘要

In a process for denitrifying furnace flue gases following dust precipitation and desulphuration, the flue gases to be denitrified are reheated by heat transfer from the denitrified flue gases in a regenerative heat-exchanger. The flue gases to be denitrified, before being heated to the final temperature, and the denitrified gases, after reduction, are fed alternately in countercurrent over heat accumulators into an additional catalyser serving as a main catalyser. The surfaces of the accumulators are provided with catalytic compounds.
