Description

Jon. Vaillant KG December 19, 1974 GM 218

Premixer No.

The present innovation relates to a premix burner according to the generic term of the 1st protection claim.

With such a so-called die-cast burner, as with other burners, an ignition electrode must be used to ignite the burner and a monitoring electrode can also be provided. the The monitoring electrode is used to monitor the flames of the burner, so that when the flames go out or when the flames are insufficient Combustion of the inflowing gas the burner is shut down.

The present innovation is based on the task of fastening or to provide attachment options for the aforementioned electrodes. With regard to the most diverse applications

-Z-

options should also be borne by Serge, that the location of the ignition electrode and monitoring electrode sys ^ suschbar should be kept. Continue to be It is important that the electrodes are no longer adjusted after they have been attached to the die-cast housing required 1st.

In the case of a premix burner, these tasks are carried out at the beginning Specified type according to the innovation by the 1m characterizing Part of the 1st protection claim specified features solved.

This new ring gsssä Ss formation results in the central axis of the burner fully symmetrical mounting points, since the bearing blocks on the other hand can be designed symmetrically if the attachment points and the electrodes are the same are. Further refinements and advantageous developments of the innovation are evident from the subclaims.

An exemplary embodiment of the innovation is based on the figures

1 to 3 of the drawing explained in more detail.

Show it:

1 shows a side view of a burner according to the invention with a mounted ignition and monitoring electrode,

2 shows the attachment of the ignition electrode on an enlarged scale and

FIG. 3 shows a side view of FIG. 2 with a partial section. In all three figures, the same reference numerals denote in each case

same details.

A premix burner 1 consists of a cast iron housing 2, water is connected to a nozzle tube via spacer bolts 3. The nozzle tube 4 has nozzles 5; the gas is fed to the nozzle tube via a gas supply tube 6.

On the housing 2 burner tubes 7 are placed in your Hegen longitudinal extension perpendicular to the plane of the drawing and which are provided with slots on their upper side 8 through which a Combustible gas-air mixture In the open air uc ^ d is burned there will.

At both ends 9 and 10 deι outer sides of the die-cast housing Section 2 each has a threaded hole U and a cam 12 attached. A further cam 13 can, but yc? not be present. In the Threaded hole 11 is a screw 14 screwed in, the one Bearing block 15 clamps against the housing 2.

Each bearing block 15 has a slot 16 on its outside, the shape of which is geometrically similar to that of the cam 12 or 13. Furthermore, each bearing block has a bore 17 for the screw 14 to pass through. The bearing blocks 15 are symmetrical with respect to the plane 18, see FIG. 3. An electrode 19 can be screwed into each bearing block 15. In the present ^r usführungsbeispiel the ignition electrode and a right ionization Qberwachungselektrode disposed to the left. A counter electrode 21 is arranged on the left bearing block 15 with a screw 20 so that an ignition spark above the burner tube 7 can jump over between the electrode 19 and the counter electrode 21.

The screw connection 14.2 serves for the bearing block 15 as Clamp connection; the slot 16 in connection with the cam 12 serves as an anti-twist device. Due to the fully symmetrical Forming the bearing block it is therefore possible to open the bearing block by simply folding it from the left side of the burner to be loosened and attached to the right side of the burner. It Vat still possible to use the individual bearing blocks in the various 3 runners and when using the same electrodes the same results with regard to ignition and to achieve monitoring quality. Due to the inclination of the electrodes In the exemplary embodiment, a particularly good ignition behavior results in relation to one another.

Expectations:
