Abstract

The insert for increasing turbulence of flue gas in the smoke flue of a heating boiler, which is surrounded by a heating medium, consists of at least one annular plate perpendicular to the axis of the smoke flue. The plate's outer edges are applied to the inner wall of the smoke flue. There may be several annular plates mounted one behind the other with a distance between them sufficient to form a flow plane of max. continuity on the inner wall of the smoke flue; the plates may be mounted on rods of a U-shaped frame. The arrangement prevents formation of a laminar barrier layer over the total heating surface, thus increasing heat transfer, and leaves the cross-section of the heating pipe free to reduce pressure losses to a min. by allowing unobstructed flow at the centre where the flue gas flow rate is highest according to parabolic speed distribution.
