Abstract

1,103,451. Flow retarders. TRIANCO Ltd. Sept. 14, 1964 [Sept. 18, 1963], No. 36753/63. Heading G3H. [Also in Division F4] A flow retarder to fit in a fire tube of a boiler comprises a rectilineal-sectioned tapering metal body having a plurality of longitudinally extending fins 4, 5 whose outer edges are parallel to the axis of the body, which locate the retarder centrally in a rectilineal fire tube to define a number of gas passages of decreasing cross-sectional area, between the retarder and the tube. The bottom end of the body is closed by a pyramidal end cap 6 either formed integrally with the plates used in the construction of the baffle, or as a detachable cap, and the top end is closed by a metal plate 7, located in position by dimples 8, to which a U-shaped metal handling rod 9 is attached. By this the retarder may be located longitudinally in the tube. The space within the retarder may be filled with slag wool. The fins may extend only part way along the retarder (Figs. 9 and 10).
