Device for lighting and monitoring of
gas-heated devices.

The -new-started-to -a ± ne device for lighting
and monitoring of gas-heated devices in which a pilot burner with an arc-shaped ignition tube, an igniter and a with
a thermoelectric !! Ignition safety device connected thermocouple are arranged on a common support plate, * which is provided with the ignition burner housing and a holder for the igniter or the thermocouple, which is positioned in relation to the ignition burner head and whose axes coincide in a common plane directed perpendicular to the plane of the support plate, wherein the gas outlet opening on the burner cup of the ignition tube is assigned a wire helix.

Devices for lighting and monitoring gas-heated devices of the type mentioned are already known. Such a device has become known, for example, from the German utility model 1 980, in which the support plate is also used as

Closure body for an installation opening of the device on a gas-heated device.

The innovation is based on the task of providing a device To create the type mentioned at the beginning for the attachment to burners of gas-heated devices.

This object is achieved in a device for igniting and monitoring gas-heated devices of the type mentioned according to the innovation in that the support plate is an arm formed on the side of the pilot burner housing, one of which is laterally delimited by the axes of the ignition tube _{9 of} the igniter and the thermocouple coincides with a certain level and at the same time is provided with semicircular recesses to hold the detonator and the thermocouple, into which the detonator and the thermocouple can be inserted from the side and screwed tight by means of a counter-holding device, which has semi-circular mounting surfaces mirror-inverted to the recesses.

For this purpose, it is provided in a preferred embodiment that the boom is approximately in the middle between the cutouts a threaded hole is provided for screwing the Gegenhaiterungsschelle by means of a screw.

Furthermore, the design is made so that that to the pilot burner housing opposite end of the boom has an angled web for screwing to the burner of the gas-heated device

Finally, it is provided that a lateral widening of the burner cup, known per se, is directed towards the boom. In the device for igniting and monitoring of gas-fired equipment according to the innovation, the support plate is formed as a lateral extension arm of the Zündbrennergehäuses at which the igniter and the thermocouple are laterally easy to screw by means of a counter support clamp _e erfordert- The fabrication of the device

compared to known designs a relatively low Effort and does not require, for example, any special screw connections to attach the thermocouple and the igniter the lateral widening of the burner cup, which is directed towards the boom, ensures good ignition of the one flowing out of the pilot burner Gas and an optimal pilot flame length for heating the thermocouple, as it flows out through the expansion Gas is drawn into the actual pilot flame by the natural buoyancy of the gas.

The subject of the innovation is explained in more detail using an exemplary embodiment shown schematically in the drawing.

Fig. 1 is a side view of the device for igniting and monitoring gas-heated devices according to the innovation with partially broken pilot burner,

FIG. 2 is a plan view of the device according to FIG. 1.

The device consists of the illustrated embodiment from an arm 10 designed as a support plate on the pilot burner housing 11, which is connected to the pilot gas supply line 12 by means of the Screw connection 13 is connected. In the pilot burner housing 11 a non-visible ignition gas nozzle is arranged, to which air intake openings 14 with a sieve 15 are assigned. In the pilot burner housing 11, the ignition tube 16 is inserted, which extends in a known manner in an arc of 90 °. The exit end of the ignition tube 16 ends in a burner cup 161 which is directed horizontally. Inside the burner cup 161 is in a manner known per se, a wire helix 17 is held, which protrudes outwardly beyond the plane of the cup opening 162. In Also known in the art, the burner cup 161 is provided with a one-sided widening 13 which is attached to the smoke opening 162 their greatest protruding extent in the radial direction,

Burner goblet 161 flowing ignition gas can flow out through the widening 18 next to the wire coil 17 and the ignition of the auxiliary gas quantity Pilot flame guaranteed »The pilot burner is used to ignite the gas-heated device, the igniter 19 with its electrode 191 and associated with the thermocouple 20 for the ignition safety device, not shown, the arrangement of which in a known manner as follows is taken that the axes of the pilot burner housing 11, the igniter 19 and the thermocouple 20 in a common lowering » right to the plane of the boom 10 E ^ ene coincide. The tip of the electrode 191 of the igniter 19 is at a distance corresponding to the spark transmission from the outlet end of the ignition tube 16 · Furthermore, the head 201 of the thermocouple 20 is so far away from the outlet opening of the ignition tube 16 that only the tip of the ignition flame is Head 201 of thermocouple 20 is applied.

According to the innovation, the support plate is on Aufnähme dee Zünuefs and of the thermocouple 20, a bracket 10 which is formed on the side of the pilot burner housing and of which one side delimitation 101 the plane determined by the axes of the ignition tube 1.6, the igniter 19 and the thermocouple 20 coincides.

The counter bracket clamp 21 is used to attach the igniter 19 and the thermocouple 20 to the boom the same mirror image, the recesses 102 and 103 on the display? 10 corresponding semicircular mounting surfaces 211 and 212. Ser boom 10 is approximately in the middle between the recesses 102 and with a threaded hole 104 for screwing on the counter holder clamp 21 provided by means of a screw 22.

The lateral widening 18 of the burner cup 161, known per se and directed towards the boom 10, improves the ignition of the pilot flame and ensures an optimal pilot flame length, since the natural buoyancy of the gas flowing out through the widening 18 into the pilot flame is used. _Λ -

The manufacture of the device for lighting and monitoring gas-heated devices is simplified according to the innovation, since In particular, there is no need for complex holders for the igniter 19 and the thermocouple 20.
