1 COMBUSTION APPARATUS BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates generally to combustion apparatus and more particularly to an improved combustion apparatus for burning a mixture of vaporized fuel and combustion air.

2. Description of the Prior Art When formulating a design for a combustion apparatus burner, it is necessary to consider those characteristics which will affect flame blow-out, back fire, the formation of soot, and the generation of combustion noise. In combustion, the formation of soot increases as the supply of primary air decreases. Similarly, flame blow-out and back-fire are dependent upon a proper ratio of primary air to fuel at the flame holes of the burner, as well as the velocity of the mixture of fuel and air. When for example, the ratio of primary air to fuel is one, if the velocity of the mixture at the flame holes is high, flame blow-out is easily caused, while if the velocity of the mixture at the flame holes is low, back tire is easily caused. The higher the ratio of primary air to fuel, the narrower the range of the velocity of the mixture within which both flame-out and back-fire will not occur. A conventional burner, such as, for example, a Bunsen burner, wherein the primary air and the secondary air are separately used as sources of combustion air, is of complicated structure. Similarly, the red flame type burner causes a great deal of soot. Accordingly, in order to simplify the structure and prevent the formation ofsoot, various burners were considered which utilized, as combustion air, the primary air and an excess of primary air which was more than the theoretically useable combustion air. Consequently, such conventional burners has the disadvantage in that they decreased the stability for flame blow-out or back fire, while large conventional burners had the added disadvantage of combustion noise.

Furthermore, in the conventional apparatus in which the combustion conditions are obtained by a complete premixing process, the range of stable combustion is quite narrow, so that a fluctuation in shape of the flame could be easily caused, thus resulting in the creation of a back fire, a low frequency sound, or a flame blow out phenomenon which was the result of, a change in the output resistance of an apparatus connected to the combustion apparatus, such as, for example, a heatexchanger, or a change in the excess air coefficient of the combustion air depending upon the temperature of the environment. Heretofore, in order to overcome the aforementioned disadvantages and to stabilize the flame, it has been proposed to finely divide the flame holes of the combustion plate and to control the combustion air by an air shutter. In said cases, however, the shape of the flame has been a lamina flow flame 18a, as shown in FIG. 2. Accordingly, it has been hard to obtain a complete stable combustion because of changes in the air density caused by a change in the environmental temperature and a consequent effect upon the resistance at the output side.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an improved combustion apparatus which will overcome the disadvantages noted heretofore.

Another object of the present invention is to provide an improved combustion apparatus which will provide easy control of the mixture velocity as well as the combustion reaction velocity.

Still another object of the present invention is to provide an improved combustion apparatus which will maintain stable combustion without the formation of soot, flame blow-out, or back-fire.

The foregoing objectives are achieved according to this invention through the provision of a combustion plate disposed between a combustion chamber and a mixture chamber, the plate having a plurality of flame holes over which are disposed aplurality of flow obstacles, the number of obstacles being less than the number of holes, thereby covering some and not others. Disposed between the holes and the obstacles is a wire net which finely divides the mixture prior to ignition. Issuance of the mixture through the holes causes collision with the obstacles, resulting in turbulent flame flow patterns upon ignition. The cross-sectional configuration of the flame holes may vary, such aiding in the attainment of stable combustion.

BRIEF DESCRIPTION OF THE DRAWINGS Various other objects, features and attendant advantages of the present invention will be more fully appreciated as the same becomes better understood from the following detailed description when considered in connection with the accompanying drawings, in which like reference characters designate like or corresponding parts throughout the several views, and wherein:

FIG. 1 is a partial sectional view of one embodiment of a combustion apparatus constructed according to this invention;

FIG. 2 is a schematic view of the shape of the flames formed by conventional apparatus;

FIG. 3 is a schematic view of the improved shape of the flames by the combustion apparatus constructed according to this invention; and

FIGS. 4 and 5 are sectional views of the combustion plate for the combustion apparatus constructed according to this invention, showing two embodiments of flame holes.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring now to the drawings, and more particularly to FIG. 1, thereof, the combustion apparatus comprises an axially located combustion chamber 1 for burning a gas mixture of vaporized fuel and combustion air, and a peripherally located heating chamber 1a, partially surrounding combustion chamber 1, for heating the combustion air which is supplied to the combustion chamber 1. A cylindrical wall portion 2 of the combustion chamber 1 has heat accumulation properties while a vaporizing tube 3, for vaporizing the liquid fuel by means of the accumulated heat, and a heater 4, for providing heat to the wall portion 2 at the initiation of the operation, are located in an upper, radially extending wall portion of combustion chamber 1. A mixing compartment 5, for mixing the vaporized fuel, sprayed from a spray nozzle 6, and the combustion air, passedthrough the combustion air heating chamber 1a, is connected to a substantially annular gas mixture passage 7 via an inlet port 8. An axially located cylinder 9 forms a gas mixture collector 10 below the combustion chamber l, a plurality of flow regulating holes 9a being provided within the bottom wall portion of cylinder 9 for connecting the gas mixture passage 7 to the gas mixture collector 10. The mixing chamber thus comprises the mixing compartment 5, the gas mixture passage 7, and the gas mixture collector 10.

An outer cylindrical housing 11 separates, in conjunction with the radially extending wall portion of combustion chamber 1, the combustion air heating chamber 1a from the gas mixture passage 7. Furthermore, an axially located combustion plate 12, having a plurality of cylindrical flame holes 12a, separates the gas mixture collector from the combustion chamber 1. A wire net 13 is provided above the combustion plate 12, while a plurality of discrete, three dimensional type of flow obstacles 14, being of a number less than that of the flame holes 12a, are mounted upon the wire net 13, so as to be respectively disposed above only some, but not all, of the flame holes 12a, the burner for combustion thus comprising the combustion plate 12, the wire net 13 and the flow obstacles 14. A radially extending spark plug is provided within the wall of combustion chamber 1, while an inlet pipe 16 supplies the vaporized fuel from the vaporizing tube 3 to the spray nozzle 6 which leads into the mixing compartment 5. An inlet pipe 17 similarly supplies combustion air from'a blower, not shown in the drawings, to the heating chamber 1a.

The operation of the combustion apparatus will now be described. During a specific time before the initiation of combustion, the heater 4, an oil pump, now shown in the drawing, and the air blower also not shown in the drawing, are operated so that the wall 2 of the combustion chamber 1 may accumulate heat by means of heater 4. Vaporizer tube 3 is likewise heated, and when liquid fuel is supplied to the vaporizing tube 3 by the oil pump, such is vaporized by the accumulated heat.

Similarly, combustion air is supplied by means of the inlet 17 to the combustion air heating chamber la, the air then being mixed within compartment 5 with the vaporized fuel sprayed from the spray nozzle 6 to result in the gas mixture. The gas mixture is subsequently passed through the inlet 8 to the gas mixture passage 7 for consequent passage through the flow regulating holes 9a to the gas mixture collector 10. The gas mixture is then divided at the flame holes 12a, of the combustion plate 12, and the wire net 13, the mixture then being ignited by the spark plug 15 to initiate the combustion within the combustion chamber 1.

Referring now to FIG. 3, it will be noted that a part of the gas mixture passing through the flame holes 120 of the combustion plate 12 collides with the flow obstacles 14 whereby a plurality of turbulent flow flame patterns 18 are formed. It has been confirmed that stable combustion can be attained with the combustion apparatus of the present invention even though the ratio, of excess air supplied to the theoretical supplied amount of the combustion air, is 1.0, whereas the air excess ratio of conventional apparatus was 1.4. In operation, the gas mixture collides with the flow obstacles 14 so as to produce a negative pressure area around the flow obstacles 14, whereby the results are turbulent flow conditions around the flow obstacles 14, the flame, by

chemical reaction, as shown by the arrows, and the 6 concentration of the ions, is increased and the velocity of flow passing through the flame holes 12a, as well as the combustion reaction velocity, are controlled.

Referring now to FIGS. 4 and 5, there is shown, respectively, other burner embodiments constructed according to this invention. The flame holes 40 of the combustion plate consist of first flame hole passages 41 and second flame hole passages 42. The first flame hole passages 41 are respectively opened to the rear or lower surface of the combustion plate 120 and each one of the first flame hole passages has a depth of I and an inner diameter of d,. The second flame hole passages 42 are respectively opened to the front or upper surface of the combustion plate 120 and each one of the second flame hole passages has a depth of 1 and an inner diameter of d the diameter d being equal to depth and wherein the diameter d of the embodiment of FIG. 4 is constant, whereas, in that embodiment of FIG. 5, d is the maximum diameter of passage 42, the passage being frusto-conical and therefore tapering downward from diameter d to diameter d of passage 41.

Still referring to FIGS. 4 and 5, the gas mixture is injected through the first flame hole passages 41 and the second passages 42 whereby they then collide with the wire net 13 which finely divides the gas mixture so that fine flames providing a lower noise of combustion are formed within the area downstream of the wire net 13. When such burners are used, the limit of back fire is dependent upon the inner diameter d, of the first flame hole passage 41. However, the limit of flame blow-out can be increased, by the effect of the wire net 13, in addition to the limit defined by the inner diameters d and d of the first and second flame hole passages, 41 and 42, respectively.

The second flame hole passages 42 can be used as an expansion area for the flow of the gas mixture injected from the first flame hole passages 41. In the structures shown in FIGS. 4 and 5, when d 1.5 d,, the flash back region of the gas mixture having the theoretical mixing rate, can be decreased, to be about one-third. Similarly, when I, z 2 d,, the unstable combustion, caused by a change in pressure within the ignition area, can be avoided so that highly stable combustion can be attained. It has also been confirmed that the effect of the wire net can be high when the mesh of the wire net is higher than 10.

It will be noted that in the above embodiments, the cross-section of the flame holes 40 of the combustion plate 120 is circular in shape. However, it is not neces sary that they be of circular cross-section, and when they are not the inner diameters a and d can be considered to be equivalent to the corresponding linear dimensions.

Obviously many modifications and variations of the present invention are possible in light of the above teachings. It is to be understood therefore, that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described herein.
