LIQUID FUEL BURNER. APPLICATION FILED DEC. 6. 1913.
1,121,873. Patented Dec. 22, 1914.
KARL 36TH, 0F RHEINGONHEIM, GERMANY.
. LIQUID-FUEL BURNER.
Specification of Letters Patent.
Application filed December 6, 1913. Serial No. 805,062.
To all whom it may concern Be it known that I, KARL Born, a subject of the German Emperor, and residing at Rheingonheim, Rheinpfalz, in the German Empire, have invented certain new and useful Improvements in Liquid-Fuel Burners, of which the following is a specification.
The invention is of flat-burner for heating with liquidfuels, more especially wlth coal-tar oil. The fiat-burners so far known of this kind labor under a disadvantage, in that the oil does not as intended) emerge from the slit-shaped nozzle with a broad surface, but draws together on account of its viscosity, so that the real object of thls burner construction is not attained. The invention does away with this defect.
In accordance with the invention a wirenet is constructed in the fuel-nozzle, thereby insuring a uniform distribution of the fuel over the whole of the nozzle aperture, so that the fuel is constantly presented in a thin uniform film to the compressed air which passes by on both sides. In this way an exceedingly good effect of the compressed air on the fuel, that is to say a thorough atomization and mixing of the latter with the air, and consequently an exceedingly good combustion and heating effect is obtained.
A further result is a much more economical and cheaper working of the burner.
An illustrated example of the object of the invention is given in the drawing:
Figure I shows the burner in longitudinal section Fig. 11 shows a view of the fuelnozzle from above Fig. 111 is a front elevation of the burner.
The flat-burner possesses a chamber a for the fuel and a chamber 1) for the compressed air, a fuel nozzle 0 and a mixture nozzle d. The fuel is introduced through the aperture c and the compressed air through the aperture 7 into the burner. From the chamher a the fuel passes into the fuel-nozzle 0 through a channel 9, and the inflow can be changed by means of the valve h. To the end the valve h is adjustable axially by means of the hand-wheel 2'.
The wire-net is constructed in the fuel nozzle, and that most fittingly to its purpose, so that it runs in a slanting-direction from top to bottom. The wire net rests in a depression or recess of the fuel nozzle which is covered by means of a plate m (not shown in Fig. 2). The Wire net extends from a vertical channel a communicating with the channel 9 down to themouth of the nozzle, covering the entire width'of the same and protruding slightly over said mouth. By this construction the fuel coming from the channel a will automatically flow in a uniform stream. downward to the nozzle and will spread over the entire face of the net. It will reach the protruding part of the net in a thin uniform film of'the same width as the nozzle mouth. The compressed air rushing past the nozzle on both sides thereof, will then take the fuel along and vaporize the same without any loss completely and without that the larger drops are torn away from the latter, so as to obtam a particularly economical working of the burner.
The mixture of fuel and air emerges from the nozzle d, the mouth 0 of which can be adjusted at will so as to change and determine the thickness of the fuel rays and thereby also the shape and intensity of the flame. With this end in view, the aperture or mouth 0 is constructed by two plates 79 and g movable in parallel planes between dove-tail guides r. The adjustment of the plates 79 and q is effected by an adjusting screw .9 provided with right and left hand thread, and working in a bearing sleeve 15. This screw enters sleeves a and o of the plates and thus the width of the aperture 0 can be regulated at will. I
What I claim as my invention is:
1. A liquid fuel chamber, a fuel supply channel having a horizontal and vertical branch leading to said chamber, a cover for said chamber and an obliquely disposed wire netting within said chamber above the vertical branch of the fuel supply channel for spreading the fuel into a thin, uniform film before feeding it to the nozzle outlet, and means for varying the size of the nozzle outlet, substantially as described. T
2. Flat fuel burner of the character described comprising in combination, a fuel means for controlling the supply of fuel to said nozzle, a channel having a horizontal and a vertical branch connecting said fuel chamber with said nozzle, means within said nozzle for spreading the fuel toa uniform film, a mixing nozzle for uniformly mixing fuel and air, and means for controlling the supply of the mixture through the burner.
3. Flat fuel burner of the character de- Patented Dec.
and a compressed air chamber, a nozzle, f
scribed comprising in combination, a fuel and an air chamber, a nozzle, a hand controlled valve for the regulationof the supply of fuel from said chamber to said nozzle, a channel having a horizontal and a vertical branch connecting the fuel chamber and said nozzle, an'obliquely disposedwire netting above the vertical branch of said channel for spreading the fuel to a uniform film, a mixing nozzle for uniformly mixing fuel and air, and means for controlling the supply of the mixture from the burner.
4;. Flat fuel burner of the character described comprising in combination, a fuel and an air chamber, a nozzle, a hand controlled valve for regulating the supply of fuel from said chamber to said nozzle, a
channel having a horizontal and a vertical branch connecting the fuel chamber and said nozzle, an obliquely disposed Wire netting above the vertical branch of said channel for spreading the fuel into a uniform film, a mixture nozzle for uniformly mixing fuel and air, and hand controlled plates for regulating the Width and shape of the opening of the mixing nozzle and the supply of the mixture from the burner.
In testimony whereof I aflix my signature in presence of two Witnesses.
