These difficulties are avoided in the present invention by supplying the oxygen-containing gas f.i. air through a plurality of exit openings arranged symmetrically about the longitudinal axis of the fuel supply nozzle. Compared with a single annular air supply gap the same quantity of air passes through the plurality of exit openings with much high velocity so that a higher re duction of the quantity of air is possible without affecting the recirculation of combustion gases. A very simple and effective means for reducing the air supply is the cutting off of some of the exit openings from the air source. The air passing through the remaining exit openings has a velocity high enough to ensure proper recirculation of combustion gases even at one tenth load of the burner.
Accordingly, it is an object of the present invention to provide a burner of the type mentioned above which enables variation of the burner capacity over a comparatively large range without adversely affecting the combustion qualities.
The exit openings are connected via pipes or passages with pressurized air supply means. These pipes or passages can be parallel to the longitudinal axis of the fuel supply nozzle or they can be inclined thereto with an angle of between 5 and 10, in special cases up to 15. Preferably the exit openings for the combustion air are located downstream of the fuel supply nozzle in order to obtain a big prechamber within which the combustion gases can react with the fuel before the combustion air is added.
The exit openings can be combined to individual groups with the openings of each group being symmetrically arranged about the fuel nozzle axis, whereby each group can be connected or disconnected to or form the air source in order to vary the capacity of the burner. Furthermore, the exit openings of one group may have a different size of the exit openings of another group. If only two exit openings are provided they are arranged diametrically opposed and may have different sizes, the smaller opening only being supplied with air at low load.
Normally the exit openings will be arranged outside the prechamber and f.i. in the wall of the mixing pipe. Nozzles can be inserted in the exit openings.
The connection and disconnection of individual exit openings or groups of exit openings can take place outside the bumer by means of valves in the supply pipes.
Further objects, features and advantages of the present invention will become apparent from the following description in connection with the drawings which show, for purposes of illustration only, some embodiments in accordance with the present invention.
DESCRIPTION OF THE DRAWINGS FIG. 1 is a sectional elevational view of a first embodiment of a burner unit according to the invention;
FIG. 2 is a cross-sectional view taken along line AA of FIG. 1;
FIG. 3 is a sectional elevational view of a second embodiment of a burner unit according to the invention with the combustion chamber omitted; and
FIG. 4 is a sectional elevational view of a third embodiment of a burner unit accordingto the invention.
DETAILED DESCRIPTION OF THE EMBODIMENT Referring now to FIGS. 1 and 2, reference numeral 7 designates a combustion chamber having a refractory lining l1 and an outlet opening 12 for the burnt gases. The combustion chamber 7 is flanged to a burner assembly generally designated 20 comprising an outer shell 21 and an inner shell 5. Centrally within inner shell 5 is arranged a mixing pipe 6 having a flange 22 with openings 23. A fuel supply nozzle 1 is arranged in the inner shell 5 co-axial with the longitudinal axis 24 of the burner unit. The space 4 between outer shell 21 and inner shell 5 is connected by a connector 3 to a blower (not shown) which supplies the combustion air. Pipes 2 extend from the space 4 into the prechamber 25 enclosed by inner shell 5 and extending up to the mixing pipe 6.
In operation the combustion air is supplied through connector 3 to space 4 and through pipes 2 into the prechamber 25. By the injector effect of the air streaming out of pipes 2 combustion gases are sucked back from the:.combustion chamber 7 through the openings.-,
23 in flange 22, through annular chamber 8 into prechamber 25 where they are mixed with the fuel emerging from fuel nozzle 1. The finely divided fuel reacts with the hot combustion gases and forms reduction products of a precombustion. These products are delivered into the mixing pipe 6 by the air jets and are mixed with the air. The mixture of fuel, recirculated combustion gases, reduction products and air emerges from the exit opening 9 of the mixing pipe 6 and is ignited by the flame vortex l0. Naturally the first ignition is effected by the usual ignition device (not shown). The burning of the mixture takes place in the combustion chamber 7.
react with the combustion gases.
As can be seen from FIG. 2, the recirculated combustion gases can flow through the interstices between the pipes 2 into the space surrounding the fuel nozzle 1. In this embodiment three groups of air pipes are formed namely a, a; b, b and c, c. Each group can be individually connected to or disconnected from the air supply. For full load all groups are supplied with air whereas for partial load one or two groups are disconnected. For this purpose a rotary valve 13 shown diagrammatically in FIG. 1 can be provided.
The embodiment of FIG. 3 differs from the embodiment of FIG. 1 only by a shorter mixing pipe 6 and longer air supply pipes 2'. Again the recirculated combustion gases enter partially the space around fuel nozzle 1 through the interstices between the air pipes 2., and partially they mix directly with the combustion air. As can be seen, the exit openings of pipes 2' are a relatively great distance from the fuel nozzle 1, thus enabling a long reaction of the fuel with the recirculated combustion gases prior to the admixture of the combustion air.
In the embodiment of FIG. 4 the combustion air is supplied to the interior of the mixing pipe 46 through openings 42 and 42' which are connected to annular chambers 48, 49 respectively, which are in turn connected to air supply pipes 43, 43. The air jets emerging from the openings 42 and 42 into the mixing pipe 46 in direction towards the combustion chamber 7 generate a pressure rise in the downstream portion 46' of the mixture pipe. This pressure rise effects a recirculation of hot combustion gases from the combustion chamber 7 through passages 41 in the wall of the mixing pipe 46 into the prechamber 50 accommodating duel nozzle 1. The fuel which mixes with the hot combustion gases has relatively long time to react therewith until it reaches the air exit openings 42, 42'. In this example the combustion chamber 7, which, owing to the good preparation of the fuel and the intimate mixing with the combustion air can be run with very high performance, is liquid-cooled. i
The air exit openings 42 of the one group are of smaller cross-section than the air exit openings 42' of the other group. The openings of each group are equally spaced around the circumference of mixing pipe 46 with one opening of one group always between two openings of the other group. According to the desired performance of the burner the one or the other or both groups are supplied with combustion air. This burner is especially suited for operation with liquid hydrocarbons which are burnt with blue flame without generation of soot and even in substochiometric mixture. However, also all combustible gases, particularly the gaseous hydrocarbons, can be burnt.
The burner of the present invention is also well suited for burning pulverized coal owing to the long reaction time available prior to the mixing with the combustion air. Furthermore, it should be pointed out that the burner can be operated with oxygen instead of air. Finally it should be remarked that the combustion air flowing through space 4 is heated and at the same time forms a heat isolation for the prechamber and the space 8 through which the combustion gases are recirculated.
Thus the several aforenoted objects and advantages are most effectively attained. Although several somewhat preferred embodiments have been disclosed and described in detail herein, it should be understood that this invention is in no sense limited thereby and its scope is to be determined by that of the appended claims.
