摘要： A flue baffle may be removed from the narrow end of a frusto-conical flue. The baffle has a plurality of hinged plates secured to a tube, and slots in the tube beneath each plate. A slidable rod extends through the tube and has a plurality of pins which extend through the slots and contact the plates. When the rod slides down, the pins also descend, and the plates collapse. When the rod is lifted upwardly, the pins push the plates apart. A dowel may be secured to the tube to communicate with the rod to secure the rod in relation to the tube and spread the plates at a pre-determined point. The width of the plates is smaller than the narrow end of the flue so that the baffle may be removed when the plates are collapsed. The plates may be skewed on the tube so that all of the gases and heat which rise through the flue are diverted toward the flue wall by at least one of the plates without excessively obstructing the flow of gases out of the flue.

摘要翻译： 烟道挡板可以从截头圆锥形烟道的窄端去除。 挡板具有固定到管的多个铰接板，以及每个板下方的管中的槽。 可滑动杆延伸穿过管并且具有多个销，其延伸穿过狭槽并接触板。 当杆滑下时，销也下降，板倒塌。 当杆向上提起时，销将板分开。 定位销可以固定到管上以与杆连通以将杆相对于管固定并将板在预定点上分散。 板的宽度小于烟道的窄端，使得当板折叠时可以移除挡板。 板可以在管上倾斜，使得通过烟道上升的所有气体和热量通过至少一个板转向烟道壁，而不会过多地阻碍气体流出烟道。
