More Information
Summary:The utility model provides denitration equipment which can remove nitrogen oxides efficiently in longer period or a replacing method of a catalyst. The denitration equipment comprises a waste gas channel (40f) allowing waste gas to flow, a rectifying and denitration catalyst layer (80) arranged on the waste gas channel (40f) and at least one denitration catalyst layer (82, 84, 86) arranged in the position, close to the downstream side of the rectifying and denitration catalyst layer (80) in the waste gas flowing direction, of the waste gas channel (40f). The length of the rectifying and denitration catalyst layer (80) in the waste gas flowing direction is shorter than the length of the denitration catalyst layers (82, 84, 86) in the waste gas flowing direction.
