Definitions

  • the invention relates to an arrangement for guiding fresh air and exhaust gas, in particular for a gas wall unit, in which an exhaust pipe is arranged essentially concentrically in a fresh air pipe passing through a wall, and in which an insulating pipe is provided which overlaps the internal exhaust pipe is held on the exhaust pipe.
  • the aim of the invention is to avoid these disadvantages and to propose an arrangement of the type mentioned at the outset in which the insulating tube can be adapted at the installation site.
  • this solution also has the advantage that the pipes are brought to the installation sites in a uniform length and are brought in place to the lengths dependent on the respective thickness of the wall to be penetrated.
  • the cutting to length of individual metallic pipes is much easier than the cutting of double pipes fitted in the factory or of pipes provided with an insulating layer, which is usually formed by a foam.
  • the length of the pipe causing the thermal insulation generally exceeds the thickness of the pipes to be penetrated.
  • the spacer rings have steps on which the insulating tube is seated.
  • the spacer rings are designed as a seal.
  • the spacer rings are made of a heat-insulating material.
  • the arrangement according to FIG. 1 has a metal fresh air pipe 1 which passes through a wall 2. Within this fresh air pipe 1 is also a metallic exhaust pipe 3 is kept concentric. A gas device, not shown, is supplied with fresh air via the annular space between these two tubes arranged one inside the other. The exhaust gas is discharged through the inner tube.
  • the exhaust pipe 3 is provided with an insulating pipe 4 for thermal insulation.
  • This insulating tube 4 is supported on the exhaust pipe 3 via two spacer rings 5, these spacer rings 5 preferably being made of a poorly heat-conducting material, such as plastic.
  • the insulating tube 4 ensures that an air jacket is present in the region of the exhaust pipe 3 near the mouth, which ensures appropriate thermal insulation for the exhaust pipe. This prevents condensate from settling on the wall of the exhaust pipe 3 when the heater (not shown) resumes operation after a lengthy break in operation, which can assume relatively low temperatures during the break in the area near the mouth.
  • the arrangement which consists of a supply air pipe 1, an exhaust pipe 3 and an insulating pipe 4 supported thereon via the spacer rings 5, is expediently completed at the place of use (FIG. 2).
  • These pipes expediently have a length sufficient for thick walls.
  • the pipes 1, 3 and 4 can then easily be cut to the dimensions x, x ', x''required for the respective thickness of the wall 2.
  • the insulating pipe 4 is arranged in the region of a pipe bend of the exhaust pipe 3.
  • the insulating tube 4 consists of two half shells 14, 14 ', the half shell 14 being provided along its longitudinal edges with open folds 15 into which the outwardly angled edges 16 of the half shell 14' can be inserted.
