ABSTRACT:
An integrated exhaust gas cooling system and method, including an expansion joint linking the system to an upstream source of exhaust gas and a pre-oxidation section through which exhaust gas travels. A hot temperature zone in which the exhaust gas is maintained at a temperature optimal for an oxidation process extends through the pre-oxidation section. An oxidation catalyst in the hot temperature zone is provided. The exhaust gas passes through the oxidation catalyst. Oxidized exhaust gas passes a post-oxidation section downstream of the oxidation catalyst. A tempering air stream is injected into the post-oxidation section to create a cool temperature zone in which the oxidized exhaust gas is cooled below the temperature in the hot temperature zone and to a temperature optimal for a reduction process. The system includes a reduction catalyst in the cool temperature zone through which the oxidized exhaust gas passes.
