Definitions
- the invention relates to a mixing device for fuel gas and air, preferably for heaters.
- the invention is based, as simple as possible in a simple way the task to allow optimal mixing of fuel gas and air.
- FIG. 1 shows a heating device with a mixing device according to the invention.
- the device has via a burner 8, which is located centrally within a heat exchanger 9.
- the burner 8, a fan 2 is connected upstream.
- the mixing device 4 according to the invention On the inlet side of the blower 2 is the mixing device 4 according to the invention; in this projects a fuel gas line Third
- the fuel gas flows in a mixing device according to the invention first outside into the fan, while the air is very strong indoors located. The centrifugal force then forces the air more strongly outwards, so that it then comes to a strong mixing with the outside methane.
- a mixing device according to the invention a significantly better Mixing achieved as in a mixing device according to the prior art.
