Description
- The present invention relates to burner nozzle for atomizing liquid fuel with assistance of compressed gas, comprising a first outlet for compressed gas, having a center axis and a second outlet for liquid fuel according to the preamble of claim 1.
- Liquefied gas as a fuel of prime movers in marine vessels and other mobile, and immobile, power plants has increasingly become of interest while the importance of environmental issues of particularly the exhaust emissions have increased.
- Liquefied gas, such as liquefied natural gas, is typically stored at extremely low temperature and due to e.g. heat transfer from surrounding a part of the gas is evaporated as so called boil off gas. Admitting the boil off gas to the atmosphere is not desired. It is known as such to burn excess gas to convert it into composition significantly less harmful to the environment.
- Such liquefied gas tanks and a fuel handling system requires also inerting of the spaces related to the tanks, pipes and so on for example for maintenance work. It is known as such to burn the gas present in the tanks and their auxiliaries to convert it into composition of non-reactive gas i.e. inert gas.

KR20150096540 WO 00/47463 A1 - Inert gas generators and boil off gas flaring arrangements often require an auxiliary burner configured to burn liquid fuel for supporting the combustion of diluted boil-off gas. A critical component in a burner is the fuel nozzle. In order to ensure that the burner operates at optimum performance when burning e.g. diesel or light fuel oil, the air and the fuel needs to be mixed in a proper and controlled manner. Further, in order to use the burner in a variety of configurations, a large turn -down ratio is required; that is, being able to maintain both the atomization grade i.e. ensuring a monodisperse and predictable spray and spray angle over a large output range.

Figure 3 illustrates a second body part of the burner nozzle according to an embodiment of the invention. -
Figure 1 depicts schematically aburner nozzle 10 for atomizing liquid fuel with assistance of compressed gas according to an embodiment of the invention. The nozzle is configured to be attached to a separate burner body or a nozzle tube in a burner body (not shown) via which liquid fuel and compressed gas, advantageously air, may be introduced into thenozzle 10, as is depicted by therespective arrows nozzle 10 for atomizing and thereafter burning the fuel. Theburner nozzle 10 is a twin fluid atomizer. The nozzle utilizes a so called Air Centre Liquid Ring, where a thin annular liquid sheet is formed and upon exit is atomized using the expanding air exiting the centre outlet. - The
burner nozzle 10 comprises afirst outlet 16 for compressed gas. The first outlet is arranged coaxially into acenter axis 18 of thenozzle 10. The compressed gas is used for assisting the atomization of liquid fuel introduced via thenozzle 10. Thus, thenozzle 10 is also provided with asecond outlet 20 for liquid fuel which is arranged rotationally symmetrically around thefirst outlet 16 in respect to thecenter axis 18. In the embodiment offigure 1 thesecond outlet 20 is anannular slit 20 which is arranged coaxially with the first outlet. It is also feasible in the scope of the invention that instead of being absolutely continuous slit thesecond outlet 20 is comprised of a number of sectional slits separated by narrow, radial support protrusions in either of body parts (not shown). The purpose of the slit is to provide an annular film of liquid fuel to flow initially out of thenozzle 10, which is then effected by the flow of compressed gas. - The
first outlet 16 comprises an outwardly extending conical portion 22, by means of which the flow of compressed gas is made to widen and directed to comprise a radial velocity component. In other words a radial cross sectional dimension of the conical portion 22 is arranged to increase towards the actual outlet. This way the flow of compressed gas and the annular film of liquid fuel coincide with each other and the fuel film is atomized into droplets and/or mist. Thefuel burner 10 further comprises agas dispersing element 24, which is arranged to thecenter axis 18 at a distance from and coaxially with thefirst outlet 16 in the direction away from thefirst outlet 16. Thegas dispersing element 24 is formed so as to further direct the flow of compressed gas into a form of hollow cone, which facilitates the formation of cone-like flow pattern of the liquid fuel droplets and/or mist. The dispersingelement 24 is rotationally symmetrical in respect to thecenter axis 18. The radial cross sectional dimension of the dispersingelement 24 is arranged to increase as the distance from thefirst outlet 16 increases. More precisely the dispersing element in thefigure 1 is conical having its apex point towards thefirst outlet 16. This will set the fuel spray to the desired angle and keep this throughout the entire flow range of the nozzle and ensures that the fuel spray is monodisperse over a wide range, further assisting in keeping the air / fuel mixture optimized. - As can be seen in the
figure 1 thefirst outlet 16 and thesecond outlet 20 are arranged to open at a common axial position i.e. thesecond outlet 20 is arranged axially at the end of the first outlet 16.In the position shown in thefigure 1 or when thecenter axis 18 is vertically oriented this means that thefirst outlet 16 and thesecond outlet 20 are arranged to open at same horizontal level. - The burner nozzle comprises a
body assembly 26 of distinct parts. Thebody assembly 26 is described in more detail with a reference to thefigures 2 and3 . The assembly comprises afirst body part 30, which is shown in thefigure 2 and asecond body part 32, which is shown in thefigure 3 . The first and the second body parts form theburner nozzle 10 when assembled such that the second body part partially encloses the first body part, as can be seen in thefigure 1 .Figure 2A shows a side view of thefirst body 30 part such that the right side shows a sectional drawing of the first body part and the left side shows a front view of the first body part.Figure 2B shows the first body part in the direction B of thefigure 2A , that is from above in the figure.Figure 3A shows a side view of the second body part such that the right side shows a sectional drawing of the second body part and the left side shows a front view of the second body part.Figure 3B shows the second body part in the direction B of thefigure 3A . - The
first body part 30 comprises agas flow channel 34, which is arranged to extend through the first body part from a first end 30', i.e. an inlet end of the burner nozzle asecond end 30" of the burner nozzle, along thecenter axis 18. Thegas flow channel 34 has a specific form such that the cross sectional area of thechannel 34 is first gradually (shown by dashed line in thefigure 2A ) or stepwise constricted, beginning from the first end, such that there is alocal constriction 36 in thechannel 34. After theconstriction 36, in the flow direction of the gas, a second end of the gas flow channel constitutes thefirst outlet 16 which outlet has a rotationally symmetrical surface 16' in thefirst body part 30, in respect to the center axis. The outer surface is rotationally symmetrical, advantageously of a shape of a cone, a cross sectional dimension of which increases as the distance from thelocal constriction 36 increases. - The
first body part 30 and thesecond body part 32 are provided withmeans 40 for aligning and retaining the first body part and the second body part in coaxial relationship with each other. For that purpose thefirst body part 30 is provided withflange part 38 at the first end 30' thereof. Thefirst body part 30 comprises afirst flange part 38 arranged at the first end 30' of thefirst body part 30. Thefirst flange part 38 is provided which one ormore alignment protrusions 40. Theprotrusion 40 may be of different form. In the embodiment offigure 1 and2 theprotrusions 40 comprise two or more dowels or alike arranged to extend from otherwise generally flat surface of theflange part 38 towards second end 30' of the first body part 30.The protrusion may be also for example an annular ring protrusion. The means 40 for aligning and retaining the first body part and the second body part in coaxial relationship with each other may also be constructed as a specific form of theflange part 42 to provide the alignment effect by the form. In thefigure 1 one can see how the first and the second body parts are aligned with each other when thedowels 40 are within the cavities 40' and theflange parts - The
first body part 30 is provided with a generally inwardly taperingouter surface 44, extending from thefirst flange part 36 in the direction from the first end 30' to thesecond end 30". More particularly the outer surface is in a form of a truncated cone in the figures. Theouter surface 44 borders partially a fuel conduit formed between thefirst body part 30 and thesecond body part 32. - The
first body part 30 is provided withaxial openings 50 arranged to thefirst flange part 38. The openings are arranged to a locations radially outside theouter surface 44 of thefirst body part 30 to open in the annular fuel conduit formed between thefirst body part 30 and thesecond body part 32 when the first and the second body parts are assembled as intended. Theopenings 50 are formed in thefirst flange part 38 such that there is practically an annular opening around theouter surface 44. - Respectively the
second body part 32 is provided with asecond flange part 42 at a first end 30' of thesecond body part 32. The first and thesecond flange parts first body part 30 and thesecond body part 32 in coaxial relationship with each other. Therefore, the second flange part comprises one or more indentations 40' spaced and formed to mate with the protrusions in thefirst flange part 38 in thefirst body part 30. In the embodiment offigure 1 and3 theindentation 40 comprise two or more cylindrical cavities or alike arranged to otherwise generally flat surface of theflange part 42. - The
second body part 32 further comprises asleeve section 46 which is axially extending from thesecond flange part 42 of thesecond body part 32. The sleeve section has substantially cylindrical outer surface having a roundedsecond end 30" edge.Internal surface 48 of the second body part is generally inwardly tapering circular surface extending from thesecond flange part 42 in the direction from the first end 30' to thesecond end 30". More particularly theinternal surface 48 is in a form of a truncated cone in the figures. An angle in respect to thecenter axis 18 of the truncated cone of thesecond body part 32 is greater than an angle of the truncated cone of thefirst body part 30. - The
sleeve section 46 of thesecond body part 32 is over theouter surface 44 of thefirst body part 30, when assembled to thefirst body part 30 as is shown in thefigure 1 . Thesecond body part 32 has anopening 52 radially inside theflange part 42 and thesleeve section 46 into which opening thefirst body part 30 is assemblable such that thefirst flange part 36 is axially against thesecond flange part 42. When thefirst body part 30 andsecond body part 32 are assembled together as is shown in thefigure 1 , thesleeve section 48 of thesecond body part 32 and theouter surface 44 of thefirst body part 30 form anannular space 54 between them, which annular space connects theaxial openings 50 in thefirst body part 30 to thesecond outlet 20 of thenozzle 10 and forms the fuel conduit formed between the first and the second part. - As can be seen in the
figure 1 and2 the dispersingelement 24 is supported from the nozzle by means of axially oriented bars or a like 28. There are three rotationally symmetrically arranged bars 28 arranged in the first body part which are fixed to the dispersingelement 24. Naturally the number ofbars 28 can vary depending on the case. It is also conceivable that the dispersingelement 24 can be supported by the bars from thesecond body part 46. However, is more advantageous to support the dispersing element from thefirst body part 30. That is because thebars 28 disturb less the formation of the fuel film, when it is only the gas, and not the liquid fuel, which need to flow passing thebars 28. The dispersingelement 24, when being in a form of a cone has advantageously a circular base. However, the benefits of the invention, at least to some extent, can be obtained by using cone-like dispersing element having a polygon having more than 5 regular sides (pentagon). In the figures, the dispersingelement 24 is depicted as a hollow cone.
