Abstract
A gas flow control arrangement for use in an exhaust gas cleaning system, comprising a duct (20) through which flue gases flow from a first end (20a) toward a second end (20b). The duct is configured to have a longitudinal expanse between its first end and its second end, and a gas flow control device (80) arranged therein. The gas flow control device further comprises at least one expanded screen (81, 82, 83, 84) arranged at an angle within the duct to distribute gas flow. A method for controlling gas flow in an exhaust gas cleaning system is also described.
