Abstract

The mixing element has two arrangements respectively comprising ridge elements (3, 4) i.e. conduit, where one of the arrangements is arranged crosswise with respect to the other arrangement. The arrangements enclose an angle not equal to 0 degrees to a main flow direction. A projection plane of the arrangements is normal to the main flow direction, and lies in intermediate spaces between the adjacent ridge elements. Each ridge element has a width (H), where relative sum of the widths in a direction of width of the mixing element is smaller than 95 percent of the width of the mixing element.
