7 Claims.
of such exhaust gases so as to eliminate ther harmful carbon monoxide content and other unburned matter therein. Other objects are to provide an exhaust gas burner of simple, economical and compact construction, which can be easily installed and repaired, which is quiet in operation, which reduces the exhaust noise without producing back pressure on the engine, and which can be adapted for use in heating a motor vehicle.
'I'he invention consists in the exhaust gas heater and in the construction, combinations and arrangements of parts hereinafter described and claimed.
In the accompanying drawings, which form part of this specification and wherein like symbols refer to like parts wherever they occur;
Fig. l is a central longitudinal sectional view of an exhaust gas burner embodying our invention, i
Fig. 2 is a side elevation of said burner,
Fig. 3 is a view looking at the discharge end of said burner,
Figs. 4, 5, 6, 'l and 8 are transverse sections on the lines 4-4, 55, 6 6, 'I--1 and 8-8, respectively, in Fig. l; and
Fig. 91s a partial side elevation of a modiiied inlet pipe construction.
The present exhaust gas burner has a central passageway therein formed by a pipe or tube A, made up of an inlet or front section I and a discharge or rear section 2 whose adjacent ends are provided with outstanding flanges 3 and 4, respectively, that are removably secured together by cap screws 5. These cap screws extend through 40 a series of circumferentially spaced lugs 5a on one of said flanges, which lugs serve to space said flanges apart and thus provide a heat insulating air space 6 therebetween. As shown in the drawings, the forward or inlet section I of the central pipe or tube A is provided with an annular rib or shoulder 1 that' cooperates with the adjacent end of the discharge section 2 to form a leakproof joint therebetween.
The inlet end of the front section I of the central tube A of the burner is enlarged, as at 8, and f provided with a series of circumferentially spaced air inlet openings or ports 9; and the passage of air through these ports is regulated by means of a Valve comprising a sleeve Ill that is rotatably mounted on the outer periphery of said enlarged portion 8 and is provided with openings I I adapted to register with the openings 9. The sleeve I0 is operated by means of a suitable push-andpull wire I2 enclosed iwithin a flexible tube I3.
Secured to the enlarged inlet end 8 of the 5 front or inlet section I of the tube A, as by screws I4, an inlet housing I5 whose front or inlet end is adapted to be sec`ured in any desired manner to the discharge end of the exhaust pipe Ii of an internal combustion engine so as to receive 10 the exhaust gases thereof. Formed integral with the inlet housing I5 4is an axial feed tube Il that is disposed concentric with but spaced from said member. This feed tube is connected intermediate its ends with the side wall of the inlet l5 housing I5 by means of a web at the rear end thereof and extends into but is spaced from the inlet or front end of the inlet section I of central tube A. The portion of the feed tube I1 located within the inlet housing I5 has a cupped front 20 end portion and is provided with a multiplicity of perforations I8; This feed tube acts as a jet and a muiller for exhaust gases coming from the engine and in conjunction with the larger capacity of said inlet housing causes such gases to flow in a steady stream into the inlet end of the main or central tube of the burner. A flexible tube I9 leads from the crank case (not shown) of the engine to the inlet end of the central tube and acts to draw from said crank `case vapors generated therein.
Mounted in the forward or inlet section I of the main tube A of the burner is a mixing device B comprising a series of radially disposed circumferentially spaced blades 20, whose rear end portions are curved or deflected laterally, as at 2i, so as to deect or spin the gas and air passing therebetween, and a plurality of longitudinally spaced interfitting conical shells 22 that are disposed with their large ends facing the curved 40 ends of said blades and are each provided with a multiplicity of perforations 23. .As shown in the drawings, the blades 20 are mounted in a sleeve 24 that has a snug fit in the tu'be and is held therein by means of a screw 25; and the cones 22 are welded at their large ends to said shell. Mounted in the tube A adjacent to the small ends of the perforated cones 22 is a spark plug 2B' for igniting the combustible mixture of air and gas as it leaves said cones. Mounted in a cup or housing 21 provided therefor on the outstanding iiange 3 of the inlet section I of the tube A is a heat responsive device 28 which operates through a tube 29, a-suitable device (not shown) for indicating the temperature oi the burner.
A cup-shaped casing 33 surrounds the dis' charge section 2 of the center tube A with its `closed end disposed opposite the discharge end of said section and with its opened end terminating short of the outstanding flange l at the forward end thereof. This cup-shaped member is spaced from and cooperates with the discharge section 2 of the central tube to form an annular chamber 3| that surrounds said section and communicates with the discharge or outlet end thereof. A cylindrical casing 32 surrounds and is spaced from the cup-shaped member 3l and coopcrates therewith to form a second annular chamber 33 around the annular chamber 3l. lThe casing 32 is provided at its forward end with an lugs 31 on said member. The outer casing 32.
extends rearwardly beyond the cup-shaped casing 33 where it terminates in a discharge end portion 33 having inwardly converging walls. This reduced discharge portion of the outer casing is provided with a series of exterior cooling passageways 33. If desired, the exhaust gas burner may be used to heat water circulating through a coil of tubing 40 placed around the casing and retained thereon by means of a shell Il containing a suitable heat insulating material 42.
Projecting axially from the closed end of the cup-shaped member or casing 30 into the outlet section 2 of the main tube A of the burneris a 'pin 43 of suitable heat retaining material. As shown in the drawings, the discharge end portion of the discharge section 2 of the main tube A of the burner is'provided with a multiplicity oi 'perforations M; and likewise, the portion of the cup 30 at the discharge end of the inner annular -chamber 3l is also provided with a multiplicity of perforations-li. In order to reduce" friction, vthe bottom of the cup 33, together with the outstanding flange l of the outlet section 2 of the main tube A are given a concave curvature. The ycentral tube or pipe A and the annular chambers 3i and 33 increase uniformly in width to the discharge -end of the device so that the capacity thereof increases constantly from the time the -gases are ignited until they are discharged into ythe atmosphere.
The operation of the hereinbeiore described exhaust gas burner is as follows: The exhaust gases of the internal combustion engine pass into the gas inlet housing I5 and thence pass into the perforated feed tube or muilier i1 thereof and are discharged from the discharge end of said tube into the inlet end of the main tube A of the burner where they are mixed with air drawn into -said tube through the valve controlled air inlet openings 9 therein. Such gases and auxiliary air supply then pass through the mixing device B where they are thoroughhrmixed by the curved blades 23 and perforated conical shells 22 thereof. This mixture is then vignited 4by the spark plug 28 as it leaves the mixing device. The products of combustion then pass from the discharge end of the main tube A into the inner annular chamber 3l and thence into the linner annular chamber 33 from which they are discharged into the atmosphere through the discharge opening into the discharge end 3l of the by cap" outer casing 32. When the amount of gas pessing through the device is suddenly increased, such excess gas will pass through the perforations M and 4l in the main tube A and in the cup-shaped casing 3l, respectively, and then swept along with ythe gases passing through the annular chambers.
3i and 33. These perforations also increase the surface exposed to the hot gases and thus shorten the time required to raise the temperature in the annular chambers to that'required to thoroughly burn all of the undesirable gases passing therethrough.
v As shown in Fig. 9, cooling iins 53 may be provided on the inlet pipe to prevent overheating thereof. .The above burner construction eihcientv'-ly and completely burns the exhaust gases of the internal combustion engine. The heated passageways insure complete combustion, the noise of the engine is muii'ied without causing any back pressure on the engine; and by reason of the substantial length of the inlet pipe and the efficiency of the mixing devices therein, the exhaust gases and air for combustion are thoroughly mixed `v without the necessity of any forced feed of air.
Obviously, numerous changes may be made without ,departing from the invention. Therefore. we do not wish to be limited to the precise construction shown and described.
