Abstract
A gas burner has a fan and a mixing device disposed at the suction side of the fan. The mixing device mixes the air taken in through an intake channel with a gas supplied to the intake channel through a gas inlet to form a gas-air mixture. The mixing device has a housing with an air inlet formed with cutouts for noise reduction.
Description
- This application claims the priority, under 35 U.S.C. §119, of European patent application EP 08 164 454, filed Sep. 16, 2008; the prior application is herewith incorporated by reference in its entirety.
- The invention relates to a gas burner with a fan and a mixing device arranged on the intake side of the fan, said mixing device mixing the air taken in through an intake channel with a gas supplied to the intake channel through a gas inlet to form a gas-air mixture.
- A gas burner of the type is described, for instance, in the published German
patent application DE 10 2005 041 691 A1. There, the gas burner has a controllable fan and a venturi mixing nozzle, in which the gas supplied through a gas port upstream of the inlet into the fan, is mixed with the intaken air. The outlet of the fan is connected to a flame tube which can be inserted into a combustion chamber of a firing plant which is passed through by the gas-air mixture. To counteract the appearance of whistling noises, the flame tube of the gas burner has a sound suppressor. - German patent DE 197 30 254 C2 also discloses a method for suppressing interfering sound emissions when combusting a gas-air mixture. The gas-air mixture is supplied to a burner with a premixing hood by way of an intake tube provided with an air intake opening, a fan and a premixing path, in which burner the mixture formation of gas and air is perfected. The path from the intake tube to the premix dome is embodied such that the volumes increase, whereby the cross-section-length ratio of the components along the path in the flow direction of the air-gas mixture increases or remains the same.
- The prior structural measures for noise reduction are disadvantageous in that these are dependent on the design of the burner and require considerable installation space. The prior art measures also result in an additional pressure loss.
- It is accordingly an object of the invention to provide a gas burner, which overcomes the above-mentioned disadvantages of the heretofore-known devices and methods of this general type and which reduces interfering noises occurring in a mixing system of a gas burner, for example as a result of thermo-acoustic oscillations, in a simple and cost-effective manner; the noise reduction measures should be possible independently of the design of the burner.
- With the foregoing and other objects in view there is provided, in accordance with the invention, a gas burner, comprising:
- a fan having an suction side;
- a mixing device disposed at the suction side of the fan, the mixing device having an intake channel for air and the intake channel for air having a gas inlet, the mixing device mixing air taken in through the intake channel for air with a gas supplied through the gas inlet to form a gas-air mixture; and
- the mixing device having a housing with an air inlet formed with cutouts for noise reduction.
- In other words, the objects of the invention are achieved by a mixing device that has a housing with an air inlet formed with cutouts for noise reduction. In a preferred embodiment of the invention the air inlet of the mixing device housing is embodied in an annular fashion and the cutouts are provided at regular intervals on the annular circumference of the air inlet for instance. The mixing device housing is preferably formed in one piece with the air inlet. The air inlet can however also be embodied as a separate part which can be connected to the mixing device housing. The intake channel of the mixing device is preferably embodied in the form of a venturi nozzle.
- In accordance with an added feature of the invention, the housing of the mixing device has an annular disk configured for connection to the suction side of the fan. In a preferred embodiment, the housing of the mixing device, the annular disk, and the gas inlet are formed in one piece. Finally, there may be provided a sound suppressor to be connected to the air inlet.
- A noise reduction through the cutouts provided on the air inlet of the mixing device is possible in a simple and cost-effective fashion and irrespective of the design of the burner. The cutouts do not require any additional installation space, as a result of which the gas burner can be embodied in a very compact manner. Also, no additional pressure loss appears along the gas-air mixing path as a result of the cutouts.
- Other features which are considered as characteristic for the invention are set forth in the appended claims.
- Although the invention is illustrated and described herein as embodied in a gas burner, it is nevertheless not intended to be limited to the details shown, since various modifications and structural changes may be made therein without departing from the spirit of the invention and within the scope and range of equivalents of the claims.
- The construction and method of operation of the invention, however, together with additional objects and advantages thereof will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings.
-
FIG. 1 is a perspective view of an exemplary embodiment of a gas burner according to the invention with a mixing device and fan; -
FIG. 2 is a perspective view of an exemplary embodiment of an additional mixing device; -
FIGS. 3 and 4 are perspective views of different exemplary embodiments of an air inlet of a mixing device; and -
FIG. 5 is a perspective view of a gas burner according to the invention with an additional sound suppressor. - Referring now to the figures of the drawing in detail and first, particularly, to
FIG. 1 thereof, there is shown a perspective view of acontrollable fan 1. Amixing device 3 with a housing is disposed at asuction side 2, orintake side 2, of thefan 1. Themixing device housing 3 has anannular disk 11, which is detachably connected to the suction side of thefan 2. The mixingdevice housing 3 can be fastened to the intake side of thefan 2 in the form of ascrew connection mixing device 3 can also form an integral part of thefan 1 or a fan part. - The
mixing device 3 has an intake channel 4, for example, a venturi nozzle, which is surrounded by themixing device housing 3. Atubular gas inlet 12 is arranged at right angles to the intake channel 4, to which gas inlet 12 agas line 40 is connected. Thegas inlet 12 is tubular and embodied such that thegas line 40 can be plugged into thegas inlet 12, with the gas line being fastened to thegas inlet 12 by means of apressure clamp 10. - The mixing
device housing 3 has anannular air inlet 5 for instance.Cutouts 6 for noise reduction are provided at regular intervals on the annular circumference of theair inlet 5 for instance. Themixing device housing 3 and theair inlet 5 is preferably formed from one piece, e.g. injection-molded from plastic. The air taken in through theair inlet 5 and the intake channel 4 is mixed with the gas supplied to the intake channel 4 through thegas inlet 12. In this way thecutouts 6 reduce the noises occurring as a result of thermoacoustic oscillations for instance. - The gas-air mixture is supplied to the gas burner through a
fan outlet 23, which is surrounded by afan flange 20. Thefan flange 20 has theopenings -

FIG. 5 shows a development of the exemplary embodiment shown inFIG. 1 . This differs from the development shown inFIG. 1 only in that asound suppressor 30 is also connected to the air inlet of themixing device housing 3. Thesound suppressor 30 can be connected to themixing device housing 3 in the form of a plug-in connection or screw connection for instance.
