Abstract: A selective catalytic reduction (SCR) system having a catalytic layer. The SCR includes a plurality of baffle members located in a position spaced apart from a front end of the catalytic layer, the plurality of baffle members reduces a flow deviation due to enlargement of a flow cross-section of a fluid in at least one direction, each of the plurality of baffle members includes a first part and a second part, the first part and the second part of each of the plurality of baffle members extends in an orthogonal direction with respect to the at least one direction of enlargement of the flow cross-section, the first part and the second part are integrated, and each of the plurality of baffle members protrudes in an inlet direction of the fluid.

Abstract: A baffle apparatus for improving a flow deviation of a fluid due to the enlargement of a flow cross-section of the fluid including a plurality of baffle members. Each of the plurality of baffle members has a first part into which the fluid enters and a second part from which the fluid flows out, the first part and the second part are integrated, the first part of each of the plurality of baffle members is at a position where the flow cross-section of the fluid is enlarged and the second part of each of the plurality of baffle members is at the position where the flow cross-section of the fluid is constant, and ends of the first parts are spaced apart from each other by a distance satisfying the equation: d i = D f ( i ) ∑ i = 1 n 1 f ( i ) , and the second parts are spaced apart from each other by a uniform distance.
