Abstract
The present application provides a fuel nozzle for use in a gas turbine. The fuel nozzle may include a mounting flange, a number of premixers attached to each other, and a number of gas pathways extending from the mounting flange to the number of premixers.
Description
- The present application relates generally to gas turbine engines and more particularly relates to the use of fuel nozzles with one fuel supply and mounting column and multiple premixers for premixing prior to combustion.
- Current fuel nozzle designs for gas turbine combustion systems generally include one central mounting and fuel supply center body per fuel nozzle or a separate fuel supply. Several fuel and air circuits may be contained within the center body. When the fuel nozzle counts is in the range of about four to six nozzles, current combustion chambers with the center bodies generally present no problem from the standpoint of distributing airflow to the more central nozzles.
- As the fuel nozzle count increases, however, the center bodies begin to restrict airflow to the more central nozzles. This restriction may cause unacceptable variations in the airflow uniformity between the center and outer fuel nozzles and between adjacent nozzles. This variation may cause uneven fuel air mixing and may result in decreased flame holding margins and non-uniform flame temperatures within the within the combustion chamber. Further, these uneven temperatures may lead to increased emissions and durability concerns.
- There is thus a desire therefore for a gas turbine combustion system with more even airflow distribution about the center and the outer nozzles, regardless of the nozzle count. Such a combustion system should maintain reduced emissions while providing flame holding margins and low combustion dynamics response over a variety of operating conditions.
- The present application thus provides a fuel nozzle for use in a gas turbine. The fuel nozzle may include a mounting flange, a number of premixers attached to each other, and a number of gas pathways extending from the mounting flange to the number of premixers.
- The present application further provides a combustion chamber. The combustion chamber may include a center nozzle with a fuel passage and a premixer and a number of outer nozzles. Each of the outer nozzles may include a number of fuel passages and a number of premixers.
- The present application further provides a fuel nozzle for use in a gas turbine. The fuel nozzle may include a mounting flange, a number of premixers attached to each other, a number of gas tubes extending from the mounting flange to the premixers, and an outer shell surrounding the fuel tubes.
- These and other features of the present application will become apparent to one of ordinary skill in the art upon review of the following detailed description when taken in conjunction with the several drawings and the appended claims.

FIG. 6 is side cross-section view of an alternative embodiment of a multiple premixer fuel nozzle as is described herein. - Referring now to the drawings, in which like numbers refer to like elements throughout the several views,
FIG. 1 shows a schematic view of agas turbine engine 10. As is known, thegas turbine engine 10 may include acompressor 20 to compress an incoming flow of air. Thecompressor 20 delivers the compressed flow of air to acombustor 30. Thecombustor 30 mixes the compressed flow of air with a compressed flow of fuel and ignites the mixture. (Although only asingle combustor 30 is shown, thegas turbine engine 10 may include any number ofcombustors 30.) The hot combustion gases are in turn delivered to aturbine 40. The hot combustion gases drive theturbine 40 so as to produce mechanical work. The mechanical work produced in theturbine 40 drives thecompressor 20 and anexternal load 50 such as an electrical generator and the like. The gas turbine engine may use natural gas, various types of syngas, and other types of fuels. - Other types of
gas turbine engines 10 may be used herein. Thegas turbine engine 10 may have other configurations and may use other types of components. Multiplegas turbine engines 10, other types of turbines, and other types of power generation equipment may be used herein together. -
FIG. 2 shows a knownfuel nozzle 100. Generally described, thefuel nozzle 100 may include aflange 110 on one end that leads to apremixer 115. Thenozzle 100 may include acenter body tube 120 that extends from theflange 110 and through thepremixer 115. Positioned within thecenter body tube 120 may be apurge air pathway 130 extending therethrough. A number offuel pathways 140 may encircle thepurge air pathway 130 and may extend from theflange 110 through thecenter body tube 120. Thefuel nozzle 100 also may include aswirler 150 positioned with thecenter body tube 120 of thepremixer 115. Theswirler 150 may extend from thecenter body tube 120 to aburner tube 160. Theswirler 150 may include a number ofvanes 170. Thefuel pathways 140 may extend from theflange 110 through thecenter body tube 120 in-part and may exit via thevanes 170 of theswirler 150. Thepremixer 115 of thefuel nozzle 100 also may include aninlet section 190 for the admission of air through theswirler 150. Other configurations of thefuel nozzle 100 and the components thereof may be used herein. - In use, gas may enter the
flange 110, pass into thepremixer 115, and exit from thevanes 170 of theswirler 150. The gas flow may mix with an incoming airflow from theinlet section 190. The gas and air flows thus may mix within thepremixer 115 and then may be ignited downstream of thefuel nozzle 100. - As is shown in
FIG. 3 ,multiple fuel nozzles 100 may be mounted within anend cover assembly 200 of acombustion chamber 205. As is shown, each of the nozzles has a singlefuel supply tube 210. The use of themultiple nozzles 100, however, may create acircuitous path 220 for the airflow, at least with respect to one ormore center nozzles 230. This restricted airflow between thecenter nozzles 230 and a number ofouter fuel nozzles 240, however, may cause unacceptable variations in the airflow. These variations may cause uneven temperatures within thecombustion chamber 205 as a whole. As described above, these uneven temperatures may lead to increase emissions and durability concerns. -
FIG. 4 shows a multiplepremixer fuel nozzle 250 as is described herein. The multiplepremixer fuel nozzle 250 also may include aflange 260 leading to acenter body tube 270. Likewise, apurge pathway 280 may extend from theflange 260 and through thecenter body tube 270. Similarly, a number offuel pathways 290 may extend from theflange 260 and through thecenter body tube 270. Other configurations may be used herein. - The multiple
premixer fuel nozzle 250 may include a number ofpremixers 300. Although three (3) premixers 300 are shown, any number ofpremixers 300 may be used. Eachpremixer 300 may include aswirler 310 positioned therein. As described above, eachswirler 310 may include a number ofvanes 320. Thefuel pathways 290 may pass through theflange 260, through thecenter body tube 270 in part, into eachpremixer 300, and exit about thevanes 320 of theswirler 310. Eachpremixer 300 also may include aburner tube 335 positioned about theswirler 310 and anair inlet section 340 in a manner similar to that described above - In use, gas flows through the
fuel pathways 290 and then into thevanes 320 of theswirler 310 of eachpremixer 300. Likewise, air passes through theinlet sections 340 and theswirlers 310 so as to mix with the gas within theburner tube 335. The mixed pathways are then ignited downstream of the multiplepremixer fuel nozzle 250. -
FIG. 5 shows the use of the multiplepremixer fuel nozzles 250 within acombustion chamber 350. As is shown, asingle fuel nozzle 100 is used as acenter nozzle 360 while a number of the multiplepremixer fuel nozzles 250 are used as a number ofouter fuel nozzles 370. As is shown, thecombustor chamber 350 has a simplifiedairflow path 380 to thecenter nozzle 360 in particular. Specifically, theairflow path 380 may have fewer restrictions as compared to the design ofFIG. 3 . Further, less restricted air access also is available to theair inlet sections 340 of eachpremixer 300 of theouter fuel nozzles 370. - The use of the multiple
premixer fuel nozzles 250 thus not only provides an even airflow distribution among thenozzles gas turbine engine 10, but use of the multiplepremixer fuel nozzles 250 also should provide a cost reduction relative to the single center body designs of thefuel nozzles 100. Moreover, the overall design of thecombustion chamber 350 also may be simplified. -
FIG. 6 shows a cross-sectional view of an alternative embodiment of a multiplepremixer fuel nozzle 400. Instead of use of thecenter body tube 270, the multiplepremixer fuel nozzle 400 may include a number offuel tubes 410 that extend from aflange 420 to a number ofpremixers 430. The space between theflange 420 and thepremixers 430 may be encased in anouter shell 440. Theouter shell 440 provides structure in the absence of thecenter body tube 270. Thefuel tubes 410 thus may be made out of flexible tubing as opposed to a structural member. Eachfuel tube 410 may be in communication with one of thepremixers 430. Theflange 420 may include a number of apertures therein including a number of fuel apertures 450 andair apertures 460. The fuel apertures 450 may be in communication with thefuel tubes 410 while theair apertures 460 may direct a flow of air towards each of thepremixers 430. Other configurations may be used herein. - The use of the
multiple fuel tubes 410 thus allows a variable flow of fuel to each of thepremixers 430. Depending upon the nature of the load, steady state conditions, and transient conditions, varying the flow of fuel may be desired to each of thepremixers 430. - It should be apparent that the foregoing relates only to certain embodiments of the present application and that numerous changes and modifications may be made herein by one of ordinary skill in the art without departing from the general spirit and scope of the invention as defined by the following claims and the equivalents thereof.
