Device for controlling the flow behavior in the heating gas channels of a heating boiler

摘要

Device for controlling the flow behavior in the heating gas channels (26) of a heating boiler, wherein a plurality of parallel heating gas ducts (26) a combustion chamber (22) at least partially surrounds the heating boiler, and wherein:– the device in the heating boiler, is or can be inserted,– the apparatus is provided with a plurality of flow guide elements (10) comprises,– the flow-guidance element (10) at least one elongate flow guide surface (12) comprises,– the flow guide surface (12) is rotated about their longitudinal axis and, as a result, the form of a propeller blade, and– the flow-guidance element (10) is or can be inserted in such a way that the flow guide surface (12) in the heating gas duct (26) is located, the longitudinal axis of the flow guide surface (12), which are perpendicular to the longitudinal axis of the heating gas channel (26) and the plane of the flow guide surface (12) to the cross-sectional plane of the heating gas channel (26) by one or more predetermined angle (20) is inclined.
