This application is a division of my application for improvements on bus heaters filed by me May 6, 1927, hearing Serial No. 189,320.
In the accompanying drawings, Fig. 1 is a sectional view diagrammatically illustrating the invention;
Figs. 2 and 3 are similar views illustrating I slight modifications.
My invention relates to the art of burning exhaust gases, particularly those from an internal-combustion engine, either to provide heat or topurify the exhaust of its poisonous and obnox ous ingredients, or for both purposes. It involves novel apparatus and novel f w asextmgmshed. On the methods, although. the present application is invention. v
It is now known that the exhaust gases from-an internal-combustion engine contain a greater or less percentage of unburned fuel which can be utilized for a second combustion. It has been proposed to ignite .the ex-. haust aftermixing air with it by an external agency, such as an electric spark, and to continue the combustion by means of the flame thus inaugurated. Therebythe combustion .Will continue even if the electric spark is 'cut ofl. In practice, however, much difiiculty has,
been encountered in maintaining the said combustion due to several unique peculiarities of the said exhaust. One of such peculiarities is that the exhaust is not under a constant pressure but comes in pufl's corresponding to the consecutive explosions in the Moreover, the pressure engine cylinders. when theengine 1s' working hard is much greater than when 1t is running light, while even under light loads its velocity is high.
Another pecularity is that the composition of the exhaust varies widely under the different operating conditions of the engine and it also difl'ers widely in the several different makes of engines. A serious result of this is that the combustion of the exhaust cannot be maintained continuously but will go out at unexpected times and will not be resumed automatically even if an electric spark is present. These twodifficulties of variable pressure and variable composition I have sucrestricted to the apparatus aspect of the said Serial No. 275,141.
yet been raised in temperature up to the {'ndling point becomes so great that the flame other hand, it is not feasible to limit the stream velocity by ob- Structing to any material extent the carryingcapacity of the pipe or conduit through which it passes because the resulting backpressure would impair the action of the engine. In exhaust burners of this type here- .tofore' proposed the exhaust has. been directed through a zig-zag route comprising a set of tube sections through which the exhaust stream-passes seriatim', the resistance presented by the several sections being the changes in the velocity of the exhaust stream added sum of the individual ones. Moreover, the said sections have been arranged concentrically'and the outer ones of large diameter have a greater surface while the friction ofthe gas-flow varies as the square of the surface area. Hence in such burners the retarding effect becomes excessive as the volume and velocity rise. It has also been difiicult to maintain an adequate mixing space for the incoming gas and air streams under the violent fluctuations of stream velocity and the resulting dislocation of the flame. Referring to Fig. 1 of the (drawings,
I willfirst describe the construction by which I overcome the aforesaid pressure and velocity difficulties. In this figure, 1 represents the exhaust pipe. At its outer extremity this pipe is surrounded by a frusto-conical sleeve A, suitably mounted on the pipe but separated therefromby an annular space: Out- 7 side of sleeve A pipe 1 at its left-hand end and providedwith slots 10 covered by a movable tubular damper 11, the position of which may adjusted is a tube B closed around by any suitable means, such as a lever, as shown. The air to be mingled with the exhaust enters through said slots 10 by injector suction the volume of air admitted being con-' trolled by the position of the damper. The tube B is continued to the right by frustoconical tube sections C and E with a cylindrical tube D interposed between them, while tube F conducts away the hot and purified gas-stream. At the entrance end of D is located a spark-plug 14, which is preferably kept in action by any known means. For instance, it may be included in the common ground connection ofthe several spark-circuits of the engine. It will be understood that the exhaust gas emerges from the tube 1 in a compact stream comparable to the waterstream from a fire-hose, having a fixed direction from which it is not readily diverted. This effect becomes more pronounced as the velocity rises. Assuming that the gas becomes ignited at spark-plug 14, the starting point of the flame will tend to vibrate back and forth violently with the violent fluctuations in velocity of the gas stream. This is due to the effort of the flame to maintain itself; the flame will move to the left as the stream velocity decreases and to the right as it increases (as viewed in Figure 1) until said velocity becomes so great that the flame can not follow owing to the limit in velocity of flame-propagation. In order to maintain an adequate mixing chamber 12 in tube A I place at the right of said chamber a metal screen 13 which will stop the leftward. play of the flame at that point. Within tubes D. E and F, I place what I term a stabilizer which consists of a tube G. shown as slightly tapered. formedof perforated metal, or at least of metal perforated at each end as shown. The perforations may be of any'desired character. Across the centre of tube G is a conical deflector H which is also' formed ofperforated metal; The diameter of tube' Gr is such as to leave afree annular space around it-inside of tube D. This space is gradually reduced to the end of tube E, but
not closed.
The action of the apparatus thus far described is as follows :-At low exhaust-velocitv the gaswillstill emerge from exhaust pipe 1 in the form of a compact jet. being. however.
able to receive into it. in mixing chamber 12.
the air sucked through the slots 10 and frusto-conical sleeve A. If the Davv screen 13 and the aforesaid stabilizer were not present, the stream of mixed exhaust gases and air would preserve its et-like character clear through into the tube 17. In other words. in spite of the slight expansion permitted by the increased diameter of chamber C. the velocity of. the mixture would be such that the stream forms with a central core-like portion which travels at a much higher speed,
' than the peripheral portion of said stream.
Nor, if the screen 13 and stabilizer are in place will the effect be materially different for the screen 13 and the deflector H are so designed as to present little obstruction to'the travel of the stream, it being important to avoid maintained in the flame area and within range of the igniting capacity of the spark-plug. Also flame jets-from the burning mass inside of tube G are projected through the holes in walls of that tube into the gas that has overflowed into the annular space around that tube. From said annular space the burning mixture and products of combustion find a free outlet without crowding the opening in deflector H. This outlet is partly through the annular space around the right-hand end of tube G and partly through the perforated walls of said tube G into the space outside of the aforesaid core or jet. The the annular space tends to direct part of the flow into the tube to add a suction draft to the part which traverses deflector H. In
in the igniting range of the flame burning within tube'Gn' By this means the outflow through tube F as the velocity'and quantityrise is not confined within the central jetcore but is more nearly uniform over the entire cross sectional area of'that tube. The
flame is not interrupted and no material back-pressure has been created.
Coming to the feature of changing composition of the gas and its effect on combustion-maintenance, percentage of burnable matter in the exhaust,
which I will here refer to as fuel, can not be reduced below a certain minimum-say about 16 per cent-without interrupting the combustion. But if kept at this minimum or slightly above it, practically the entire fuel contraction of.
I have discovered that the contents will be burned. Thus, by adding.-
two or three per cent. itself. an insignificant factor in the heating, the aforesaid 16 per cent, which would otherwise be lost, can be utilized, while the combustion-interruption can be eliminated. Referring again to Fig. 1, a small tank of liquid fuel, such as kerosene, is shown at 5. From a point inside this tank, near the bottom, a
small tube M extends to a point on exhaust pipe 1 just back of the aforesaid tube B,
where it opens into the pipe. A needle-valve 3 controls the flow in this pipe M. I provide pressure on liquid in the tank by any suitable of fuel, which is, in
means, such as a pressure-pump 7 driven by the engines and introducing air by pipes 6 and 8. Thus asmall inflow of liquid fuel into the exhaust will be maintained so long as the engine is operating and of a magnitude corresponding to the engine speed. Knowing the aforesaid minimum percentage of fuel required to maintain combustion this artificial injection of fuel can be made approximately sufficient to prevent the percentage falling below that minimum, while any excess is unobjectionable and can even be made to contribute to the heating effect. So far as concerns its function of maintaining continuity of combustion, it need be no material I factor in the heating.
By combining the aforesaid stabilizing means and the supplementary fuel supply, I am able to burn the exhaust without interruption under all practical conditions. It may also be remarked that the variationswhich affect exhaust combustion are-wideand violent. 1
In Fig. 2 I- have shown, as the means for feeding the supplementary fuel, an automatic electric pump 18 of the bellows type which is a known device for such purposes. In Fig. 3
the pressure is supplied from the exhaust air supply, for example, or back of that point as shown in the drawings.
