REGENERATIVE OXIDATION APPARATUS WITH SELECTIVE CATALYTIC REDUCTION AND SELECTIVE NON-CATALYTIC REDUCTION FUNCTIONS

WIPO Patent Application WO/2023/018036

A1

Disclosed is a regenerative oxidation apparatus capable of removing high-concentration nitrogen compounds contained in exhaust gas by selective catalytic reduction and non-catalytic reduction as well as removing VOCs or odorous components. The present invention provides a regenerative combustion system comprising: a combustion chamber for oxidizing process gas; and a heat exchange layer, which is in contact with the combustion chamber and includes a plurality of sectors to perform heat-exchange with the process gas, wherein the process gas flows through an inflow heat exchange layer, the combustion chamber, and an outflow heat exchange layer; the heat exchange layer includes heat storage layers in a multilayer structure, and performs selective catalytic reduction of nitrogen compounds in the process gas by including an SCR layer disposed between the heat storage layers to remove nitrogen compounds and a first reducer supply part for supplying a reducer from the front of the SCR layer on the flow path of the process gas; and the combustion chamber performs selective non-catalytic reduction by further including a second reducer supply part for removing nitrogen compounds.
