Abstract | Device for introducing hot gas into a heat exchange tube of a waste heat boiler comprises an inner pipe connected to an outer pipe through a reversing cap to define an inlet opening for the hot gas, and a coolant pipe between the inner and outer pipes. The inflow section and at least part of the outflow section of the inner pipe define a conical region that tapers inwards in the direction of the outflow section with at least two different taper angles of less than 2[deg]. Device for introducing hot gas into a heat exchange tube of a waste heat boiler comprises an outer pipe (3) fixed to the wall of the boiler, an inner pipe (5) connected to the outer pipe through a rounded reversing cap (6) to define an inlet opening (16) for the hot gas (7), and a coolant pipe (4) extending between the inner and outer pipes almost to the reversing cap. The inflow section (17) of the inner pipe and at least part of the outflow section (18) of the inner pipe, i.e. the section connected to the heat exchange tube, define a conical region (19) that tapers inwards in the direction of the outflow section, has a length at least 4 times the inside diameter of the inner pipe and has at least two different taper angles of less than 2[deg]. |
