Definitions
- the invention relates to a forced draft burner with a a first hole pattern, towards the flame side bulging burner plate and a corresponding one with a second hole pattern, with the Burner plate positively connected and under it arranged distributor plate, which also with connected to a burner housing comprising its edges is.
- Such a forced draft burner is e.g. by the company SUPERGAS, now FURI-GAS manufactured.
- Fig. 1 is a schematic perspective Representation of the state of the art Fan burner shown.
- the one generally designated 1 Fan burner is essentially cuboid. His Top side, the burner plate provided with the hole pattern S. 3 wears, is arched upwards.
- Fig. 1 are the Longitudinal edges of the burner plate with the reference number 8 and the shorter curved front edges designated 9.
- FIG. 2 shows, as in the state the technology, the distributor plate 4 with the burner housing 2 along the longitudinal edge 8 by a weld 7 and with the burner plate 3 over the same along the longitudinal edge 8 attached knobs 6 and corresponding holes 5 is made in the distributor plate 4.
- These connections the corresponding hole patterns of the Burner plate 3 and the distributor plate 4 positionally fix to each other.
- the expansion when heating the two sheets is in the longitudinal direction through slots 5 in Distribution plate 4 and in the transverse direction by a diagonal Arrangement of the knob fixation using the knobs 6 guaranteed.
- the rags are from Burner plate bent down, i.e. in the the Opposite side of the flame, and reach through this is how the slots in the distributor plate fit.
- the burner plate and Distributor plate preferably rectangular, and the rag on the burner plate and the corresponding slots in the distributor plate lie diagonally on two of each other opposite corner sections of the rectangular Sheets. In this way, the warming of the Sheets caught in the transverse direction caused expansion.
- the slots in the distributor plate are preferably elongated holes trained, the longitudinal direction in the longitudinal direction of the distributor plate. In this way, the Thermal expansion of the distributor plate in its Catch lengthways.
- the free ends of the tabs of the Burner plate towards the shorter side of the rectangle see above that the inner radius of the lobes to the center of the burner plate points.
- the longitudinal side adjacent to this inner radius of the elongated holes an extension towards the free End of the rag.
- the positive connection of the burner housing with the The distributor plate can either be the corresponding holes or slots in the Reach through the burner housing, or alternatively by Burner housing formed inwardly projecting lobes be carried out so the longitudinal edges of the distributor plate grasp that this in the inner curvature of the housing is tense.
- FIG. 3 The cross-sectional view in Fig. 3, the sectional plane through the attachment points of the burner plate 13 on Distribution plate 14 and the latter on the burner housing 12 is placed, shows that the burner plate 13 near the Long edge 18 one down, i.e. from the flame side bent tabs 16.
- the tab 16 reaches through a corresponding slot 15 in the distributor plate 14.
- the latter is by a weld 17 on the burner housing 12 fixed. 3 does not show that the burner plate 13 has two tabs 16, the each at diagonally opposite corner sections of the burner plate 13 are bent.
- the slots 15 are formed as elongated holes, the Longitudinal side in the longitudinal direction of the distributor plate 14 is aligned.
- the inner radius of the flap or the flap 16 can be as large as possible Long sides of the slots 15 in the distributor plate 14 forming elongated holes bent down, i.e. that this Distribution plate 14 at this point one to the free end of the Rag 16 has indicative passage. So both the distributor plate 14 and the burner plate 13 as close as possible to the inner wall of the burner housing 12 can apply, the burner housing 12 has an in Longitudinal step 10.
- FIG. 4 shows a second embodiment according to the invention of the forced draft burner.
- the fixation of the burner plate 13 on The distributor plate 24 is designed in exactly the same way as in FIG Fig. 3 embodiment shown. Is executed differently in Fig. 4, however, the connection of the distributor plate 24 on the Burner housing 22.
- the distributor plate 24 detects above, i.e. Rag bent towards the side of the flame 25, and the burner housing 22 corresponding elongated holes 23 through which the tabs 25 grip.
- the in Fig. 4 Fixation of the distributor plate 24 shown on the burner housing 22 avoids the weld 17 according to FIG. 3 and contributes to this at, the temperature resistance of the burner even more improve.
- the third embodiment of the Fan burner according to the invention is what the fixation of the burner plate 13 on the distributor plate 34 also applies carried out as in the embodiments described above according to Figures 3 and 4.
- the attachment of the Distribution plate 34 on the burner housing 32 represents the in Fig. 5 shown embodiment according to the invention, however Alternative to the fixation in Fig. 4.
- the burner housing 32 is similar to that in FIG Fig. 3 a stage 35, which in the longitudinal direction of the Burner housing, i.e. goes parallel to the longitudinal edge 38. All connections of the in the figures 3 to 5 Embodiments shown are manufacturing technology easy and inexpensive to manufacture.
- the different Rag 16, 25 and 31 can be stamped and Bending step to be attached to the sheets.
- the slots 15 in the distributor plates 14 and 24 can be advantageous along with the hole patterns, for example through Laser technology.
- the extensions 19 can be put together by a bending process, e.g. in Fig. 4 be formed by bending the tabs 25.
- Fan burner according to the invention simple and inexpensive in compliance with for proper operation required correspondence of the hole pattern of the burner sheet and realize the distributor plate, and through Expansion and thermal stress caused cracking on the Weld seam is avoided.
