FUEL ATOMIZER Filed Oct. 25, 1928 Patented Apr. 26,
UNITED STATES EMIL KNOPI-IIUS, OF BERLIN, GERMANY, ASSIGNOR TO GESELLSCI-IAFT rel. RA-
I'IONELLE VERBRENNUN'G M. B. IL, OF FRANKFORT-ON-THE-MAIN, GERMANY FUEL ATOMIZER Application filed October 25, 1928, serial No. 314,981, and in Germany October 29, 1927.
This invention relates to a fuel atomizer, in which the atomization is effected by rotary members.
According to the invention, the automizer consists of a tubular casing, which is divided at a suitable point by means of a partition, whereby this partition is furnished with one or more series of apertures. In front of the partition and conforming therewith is provided a disc, which is freely rotatable and is also furnished with one or more series of apertures. The apertures in the partition and in the rotary disc are angular to each other, so that the rotation of the disc is performed by the fluid flowing through the apertures in the fixed wall and striking against the walls of the apertures in the disc. The atomizer may be employed both for liquid as well as pulverulent or solid fuel. The fuel is introduced in the centre of the casing to the space which is bounded on the one hand by the fixed partition and on the other hand by the rotary disc. The same flows against the rotary disc, and by the action of centrifugal force is flung towards the edge thereof, where it forms a film over the mouths of the apertures. The rotation of the disc is performed by an axially moving current of gas or air, this current penetrating through the apertures in the fixed wall and striking against the walls of the apertures in the rotary disc, an efiect similar to that occurring in a turbine.
The atomization of the fuel is performed by this current of air or gas, which breaks up the film of fuel covering the mouths of the apertures in the disc.
The central feed pipe may also be made to be displaceable, so that the fuel is then introduced not exactly at the centre but at certain points between the centre and the periphery of the disc.
The invention is illustrated diagrammatically in the accompanying drawings, in which Fig. 1 is a longitudinal section through the atomizer,
Fig. 2 being a cross-section along the line IIII in Fig. 1.
Fig. 3 is a view similar to Fig. 2 of a modification in which gas pipes 11 are provided.
Figure 4 is a fragmentary face view of the disc 6 showing the disposition of the apertures 7.
Referring now to the drawings, 1 represents the tubular casing of the atomizer. At a suitable point of this casing is provided a partition 2, which closes off the cross-section thereof. In the case of the particular embodiment shown this partition is furnished with circularly disposed apertures 8, which are situated at an inclination to the longitudinal middle axis. At a certain distance in front of the partition 2, but nevertheless in relatively close proximity thereto, is provided a freely rotatable disc 6 mounted on a shaft 4 and a bearing 5. This disc is likewise furnished with circularly disposed apertures 7, which are situated opposite to the apertures 3 and at an inclination thereto and disposed obliquely to radial planes passing through the axis of the disc, as shown in Figures 1 and 4. 8 is the feed pipe for the fuel, this pipe penetrating the partition 2 and opening out at 9 into the space '10, which is bounded on the one hand by the wall 2 and on the other hand by the disc 6. The liquid or solid fuel is fed in the direction of the arrow P, while the air, which is to be admixed with the fuel, moves in the direction of the arrow P.
It is also possible to introduce both air and gas, whereby a number of the apertures 3, for example two of the same, are connected directly with gas pipes 11, in order in this manner to convey a mixture of gas and air into the space 10. The face areas of the partition 2 and the disc 6, which are situated opposite to each other, may be constructed as disintegrating or grinding faces, so that for example a granular fuel which is introduced through the pipe 8 may be additionally disintegrated between the discs, to be then conveyed to the circularly disposed apertures by the centrifugal force.
The operation of the apparatus is as follows: The air, which flows from a suitable compressed air source in the direction of the arrow P into the casing 1, pursues its way through the apertures 3 and strikes against the walls of the apertures 7 in the disc 6,
whereby, the action being similar to that in the case of a turbine, the disc is caused to rotate. The fuel, which is introduced in the direction of the arrow P, passes into the chamber 10 and on to the rotary disc 6 where, by reason of the centrifugal force acting in the direction of the arrow P it is conveyed towards the edge of the disc. If, for example, the fuel employed is oil, the latter moves in the form of a thin screen or film over the face side of the disc, this screen or film extending to the edgeand also covering the mouths of the apertures 7. Since upon the rotation of the disc 6 the mouths of the apertures 7 move alternately into line with the mouths of the borings 3, the compressed air, forcing itsway through the screen or film of oil, enters the borings7, whereby extensive atomization of the fuel and also intimate commingling with the combustion air is caused. The film or screen of fuel covering the mouths of the apertures 7 is penetrated by the compressed air at innumerable points and split up into the minutest particles.
If in place of oil a granular fuel is employed, which is subjected to an additional disintegrating or grinding process between the disc 6 and the wall 2, merely the smallest particles of ground fuel, acted upon by the centrifugal force, move towards the edge of the disc, while the fuel which has been insufficiently disintegrated is subjected to the grinding process between the discs until it is reduced to such size that it is capable of being conveyed to the edge of the disc by the centrifugal force. By displacement of the fuel opening 9 towards the edge of the disc the vacuum is decreased which acts on the fuel in consequence of the rotation of the disc, so that simple regulation is possible if the current of air is to remain unaltered; otherwise the conveyance of fuel varies together with varying air pressure or varying rotation respectively.
What I claim as new and desire to secure by Letters Patent is:
In a fuelv atomizer, a tubular casing, a fixed wall in the said casing furnished. with apertures, a rotary disc situated infront of the said wall and also furnished with apertures conforming with the apertures in the said wall, and means for feeding the fuel, the said wall and the said disc having grinding surfaces cooperating to constitute a disintegrating or grinding means for the fuel.
In testimony whereof I have affixed my signature.
EMIL KNOPHIUS.
