Abstract:
1. An integrated exhaust gas cooling system comprising: an expansion joint linking the integrated exhaust gas cooling system to an upstream source of exhaust gas; a pre-oxidation section through which exhaust gas travels, equipped with a flow straightening device, wherein a hot temperature zone in which the exhaust gas is maintained at a temperature in a temperature range that is optimal for an oxidation process extends through the pre-oxidation section; an CO oxidation catalyst, in the hot temperature zone extending from the pre-oxidation section and downstream from the pre-oxidation section to a tempering air injection point, wherein the exhaust gas passes through the oxidation catalyst; a post-oxidation section downstream of the oxidation catalyst and through which the oxidized exhaust gas passes, wherein a tempering air stream is injected into the post-oxidation section to create a cool temperature zone that extends through the post-oxidation section and in which the oxidized exhaust gas is cooled below the temperature in the hot temperature zone and to a temperature in a temperature range that is optimal for a reduction process; and a NO
