Abstract
A method for treating and neutralizing environmentally harmful and/or toxic exhaust gases from industrial process plants through thermal conversion or splitting of the exhaust gases in a combustion chamber includes mixing the exhaust gases in the combustion chamber with remotely generated heated air from a separate air heater to a temperature above the ignition temperature of the exhaust gases, and, after ignition of the exhaust gases, the air fed from the air heater continues to be fed at a temperature below the ignition temperature of the exhaust gases so as to continue the thermal splitting.

A method for treating and neutralizing environmentally harmful and/or toxic exhaust gases from industrial process plants through thermal conversion or splitting of the exhaust gases in a combustion chamber, comprising mixing the exhaust gases in the combustion chamber with remotely generated heated air from a separate air heater to a temperature above the ignition temperature of the exhaust gases, and after ignition of the exhaust gases, the air fed from the air heater continues to be fed at a temperature below the ignition temperature of the exhaust gases so as to continue the thermal splitting.
An apparatus for carrying out the method for treating and neutralizing environmentally harmful and/or toxic exhaust gases from industrial process plants through thermal conversion or splitting of the exhaust gases in a combustion chamber, said apparatus being provided with a feed apparatus for air and exhaust gases and ending in the combustion chamber, comprising:
- a central air nozzle connected to an air heater outside the combustion chamber by way of the feed apparatus and, wherein the central air nozzle is equipped on the inlet side to the combustion chamber with a swirl-inducing device including a round insert which is provided with baffle plates and air passages therebetween and is arranged centrally in the outlet of the central air nozzle in order to swirl the air fed from the air heater and air entering the combustion chamber in a mixing region to form a cone of flame.
