Abstract

Exhaust gas flue for the exhaust gases, which are to be treated and/or have been treated, of an exhaust gas purification plant with flow guide elements, in particular in the region of a bend or of a knee, the flow guide elements having curved flow guide surfaces. The flow guide elements are designed to be self-supporting in the form of curved glass sheets. The glass sheets can themselves be pre-tensioned. <IMAGE>
