Abstract

Abstract The main duct section, which is arranged vertically in zig-zag shape, consists of at least two and up to 32 or more construction elements of the same size and shape. The lower element faces are inclined 40-45 degrees to the vertical so that they are vertically inclined at 100-80 degrees. The highest cross-section plane of each element is 37 plus-or-minus 4.5% greater than the lowest one. The distances between these and between intermediate cross-sections are extended depending on the inclination of the element.
