Description
- This application is the US National Stage of International Application No. PCT/EP2007/051141, filed Feb. 7, 2007 and claims the benefit thereof. The International Application claims the benefits of European application No. 06005106.7 filed Mar. 13, 2006, both of the applications are incorporated by reference herein in their entirety.
- The present invention relates to a combustor comprising in flow series a burner, a transition piece and a combustion chamber being of larger diameter than the transition piece, the combustion chamber being connected to the transition piece via a dome portion. In addition, the invention relates to a method of operating a combustor, especially a combustor of a gas turbine.
- Modern gas turbine engines use the concept of premixing air and fuel in lean stoichiometry before the combustion of the fuel/air mixture. Usually, the pre-mixing takes place by injecting fuel into an air stream in a swirling zone of a combustor which is located upstream from the combustion zone. The swirling leads to a mixing of fuel and air before the mixture enters the combustion zone.
- U.S. Pat. No. 6,532,726 B2 describes a gas turbine engine system having a combustor with a burner head having injection arrangements for gas- and liquid-fuel operations. During both gas- and liquid-fuel operations the flame front face is located close to the burner head and, during liquid-fuel operations, air is forced across the downstream face to cool the head.
- The aerodynamics in the combustor dome comprise of a annular recirculation bubble that has a helical flow pattern in the circumferential sense. This recirculation bubble is driven by the swirling flow emerging from the pre-chamber. Currently, it is known that at low machine loads the highest combustion efficiency can be achieved if the flame front is fully stabilised in the dome recirculation bubble. Poor efficiency is associated with a flame front stabilised in the central recirculation bubble, which is predominantly located in the pre-chamber area. At high machine loads, the central recirculation bubble has sufficient swirl and intensity for the flame front to be fully held.
- However, the combustion system has relatively poor combustion efficiency at low loads and at starting conditions. This problem exists for liquid and gas operation, although it is most noticeable on liquid.
- With respect to the mentioned state of the art it is an objective of the invention to provide a combustor, in particular a gas turbine combustor, and a method of operating a combustor, especially a gas turbine combustor which is advantageous in providing a combustion efficiency at low loads and starting.
- This objective is solved by a combustor according to the claims and a method according to the claims. The dependent claims describe advantageous developments of the invention.
- The inventive combustor comprises in flow series a burner, a transition piece and a combustion chamber being of larger diameter than the transition piece. The combustion chamber is connected to the transition piece via a dome portion. Air injection openings are located in the dome portion. In particular, the transition piece may also be referred to as a pre-chamber in regard to the combustion chamber.
- It is believed that the state of the art dome recirculation bubble strength is only marginally insufficient and that limited additional air directed the appropriate way will improve the efficiency of the combustion system. To improve the dome recirculation efficiency where a machine would be operating predominantly in the low load regime, it is therefore proposed that air is introduced across the dome to supplement the existing aerodynamics and enhance stability.
- In an advantageous embodiment of the present invention the openings comprise a first row of openings being positioned at a circle of a first radius of the dome portion and at least one further row of openings being positioned at least one further circle of a second radius of the dome portion being different to the first radius. Advantageously, the openings have an elongated shape with a long direction and a short direction. Especially, the openings have a shape of an ellipse. However, the openings can be of any other shape.
- The openings of the first and the at least one further row can have a defined orientation e.g. such as the openings being positioned at an innermost circle of the dome portion are oriented tangentially with their elongated direction and the openings being positioned at the outermost circle of the dome portion have no tangential component in their elongated direction. The orientation of openings being arranged in further rows lying between the rows being positioned at the innermost and the outermost radius may be then dependent on the radius at which they are positioned. Especially, the tangential component proportion of an openings long direction increases as nearer the opening is positioned at the innermost radius of the dome portion and decreases as nearer the opening is positioned at the outermost radius of the dome portion. In addition duct portions of ducts for feeding the air to the opening adjoining the air injection openings are designed so that they have angles of inclination to the surface normal of the dome surface greater than 45 degrees and less than 80 degrees. When angled jets have angles of inclination to the surface front to which they emerge of less than 11 degrees (i.e. of more than 80 degrees relative to the surface normal) it will be difficult to attach them to the surface of the surface.
- With the described configuration of the openings, an air jet streaming through an opening of a row being positioned at the outermost radius of the dome portion has no tangential component. Air jets flowing through openings of the other rows have tangential components that increase with decreasing radial position.
- Advantageously, the first row of openings is arranged close to a dome edge, where the dome portion is adjacent the transition piece.
- The number of openings of the first row may be greater than the number of openings of the at least one further row. The higher number of openings ensures a sufficient introduction of air near the transition piece due to provision of greater air penetration.
- Further, the openings of the first row are advantageously each smaller than openings of the at least one further row. Due to the greater number and the smaller diameter of these openings, an even introduction of air to the partially premixed gases leaving the transition piece is achieved.
- The inventive combustor is particularly adapted to perform the inventive method.
- The inventive method of operating a combustor which comprises in flow series a burner, a transition piece and a combustion chamber being of larger diameter than the transition piece and being connected to it via a dome portion comprises the step of introducing air from the dome portion of the combustor.
- In an advantageous embodiment of the present invention, the air is introduced by an inclination angle to the surface normal of the dome surface greater than 45 degrees and less than 80 degrees.
- Further features, properties and advantages of the present invention will become clear from the following description of embodiments of the invention in conjunction with the accompanying drawings.
-
FIG. 1 shows a combustor according to the invention; -
FIG. 2 shows a dome plate according to the present invention; and -
FIG. 3 shows another dome plate according to the present invention. -
FIG. 1 shows a combustor according to the invention. The combustor comprises in flow direction series aburner 10 withswirler portion 12 and a burner-head portion 11 attached to theswirler portion 12, a transition piece being referred as combustion pre-chamber 13 and amain combustion chamber 4. Themain combustion chamber 4 has a diameter being larger than the diameter of the pre-chamber 13. Themain combustion chamber 4 is connected to the pre-chamber 13 via adome portion 30 comprising adome plate 38. In general, thetransition piece 13 may be implemented as a one part continuation of theburner 10 towards thecombustion chamber 4, as a one part continuation of thecombustion chamber 4 towards theburner 10, or as a separate part between theburner 10 and thecombustion chamber 4. - The combustor is adapted to be operated with either liquid or gaseous fuel and comprises a gas-fuel injection system, a liquid-fuel injection system and an air injection system.
- The gas-fuel injection system comprises main gas-
fuel openings 23 and a pilot gas system. The main gas-fuel openings 23 are located at an air-inlet region of aburner head face 16, i.e. of theswirler portion 12, i.e. adjacent a radially outer part ofpassages 14 which are defined between a number of vanes of theswirler portion 12 and are fed fromconnectors 24. The pilot gas system comprises in flowing direction of pilot gas aconnector 18 at theburner head 11, anannular gallery 19,gas outlets 32, alip 20 extending radially inwards towards thelongitudinal axis 21 of the combustor, and a central part 22 being arranged on aburner head face 16. - The liquid-fuel injection system comprises liquid-
fuel pilot openings 25 and main liquid-fuel openings 27. The liquid-fuel pilot openings 25 can inject liquid fuel fed fromconnections 26 through appropriate ducts extending through theburner head 11 into the pre-chamber 13. Thepilot openings 25 are positioned in the central part 22 of theburner head face 16 outside the outer circumference of the combustion flames front FF. The main liquid-fuel openings 27 are fed fromfuel connectors 28 through appropriate passageways extending through theburner head 11. The main liquid-fuel openings 27 are situated in theburner head face 16 at or near the air-exit region of theswirler 12, i.e., near a radially inner portion of theswirler passages 14. - The air injection system comprises
air ducts 36 leading toopenings dome plate 38. The exit parts of the ducts, i.e. the parts adjoining the openings, are inclined with respect to the surface normal of thedome pate 38 by an inclination angle α. - In operation,
compressed air 15 is supplied to theburner 10 and streams through theswirler passages 14. The in streaming air mixes with fuel injected into the compressed air streams through the passages from injection openings located in a peripheral section of theburner head face 16. On arriving in the pre-chamber 13, the mixture is ignited by an igniter unit 17. Once lit, the flame continuous to burn so that a further ignition is not required. - When the engine is started in gas-fuel mode of operation, the pilot gas supplied through the
connector 18 at theburner head 11 streams through passages in theburner head 11 arriving at theannular gallery 19. From there the pilot gas is directed via thegas outlets 32 to the underside of a directing means in the form of thelip 20 extending radially inwards towards thelongitudinal axis 21 of the combustor. Thelip 20 deflects the pilot gas across the central portion 22. However, as engine load and speed increase, the pilot gas supply is reduced and the main gas-fuel supply is increased. The main gas-fuel exits the main gas-fuel openings 23. The main gas-fuel and the air mix together as they pass theswirler passages 14 on their way to a combustion flame withinpre-chamber 13 and main-chamber 4. - Further,
air jets 34 are supplied by theair openings 36 intomain combustion chamber 4. Therein, they mix in dependence of engine load with either with the pilot gas, the fuel-air mixture and/or the combustion products of them so as to improve the dome recirculation efficiency by providing sufficient swirl and intensity for the flame front. The injectedair jets 34 have an inclination angle α in relation to the surface normal of the dome surface being shown as dashed line. - When the engine is started in the liquid-fuel mode of the combustor, pilot liquid-fuel is injected from
pilot openings 25 into the pre-chamber 13 in an axial direction which is at least approximately parallel to the centrallongitudinal axis 21, where it mixes withair 15 exiting theswirler passages 14. The obtained mixture of air and fuel is ignited by the igniter unit 17. And further mixtures of air and fuel are fed to the so obtained flame F. - Additionally, the
air jets 34 are supplied by theair openings 36 into themain combustion chamber 4. Therein, they mix with the mixture which leaves the pre-chamber 13. This mixture can comprise the pilot fuel, the air-fuel mixture being introduced into the combustor and/or their combustion products. Due to the orientation of the exit parts of theducts 36 theair jets 34 have an inclination angle α in relation to the surface normal of the dome surface being shown as dashed line to compliment the existing aerodynamics and enhance the stability, especially, when the gas turbine is operating in the low load regime. - As engine load increases from start-up to approximately 70% full load, the supply of liquid pilot fuel is reduced, and main liquid fuel is introduced from the main liquid-
fuel openings 27 which are located on the burner face in the air exit region of theswirler passages 14 and inject main liquid fuel in a direction approximately perpendicular to theair stream flow 15. The supply ofair jets 34 can either be continued or stopped. -
FIG. 2 shows a dome portion according to the present invention. The dome portion comprises aplate 200 having a first row ofopenings 202, a second row ofopenings 204 and a third row ofopenings 206. All openings have an elongated shape defining a long direction of the openings. - The
openings 202 are positioned at the innermost radius of theplate 200 and closest to thedome edge 208. They are oriented near tangential to thedome edge 208 with their long direction. Theopenings 204 are arranged at radius being greater than the previous radius. Their orientation is less tangential than that of theopenings 202 of the first row. Theopenings 206 are situated at the outermost radius and are oriented radially inwards with no tangential component of their long direction. - Through
openings openings FIG. 1 ). The inclination angle α lies in the range of 45°<α<80°. The jets streaming outopenings 206 do not have a tangential component in regard to thedome edge 208, while the others have a tangential component. The flow direction of the air jets is shown by arrows. -
FIG. 3 shows another dome portion according to the present invention. The dome portion comprises aplate 300 having a first row ofopenings 302, a second row ofopenings 304 and a third row ofopenings 306. - The
openings 302 are positioned at the innermost radius of theplate 300 and closest to thedome edge 308 and are oriented near tangential to thedome edge 308. Theopenings 304 are arranged at radius being greater than the previous radius and are oriented less tangential than theopenings 302. Theopenings 306 are situated at the outermost radius and are oriented radially inwards with no circumferential component. - The number of
openings 302 is greater as the number ofopenings 304 or the number ofopenings 306 Further, the diameters of theopenings 302 are smaller than the diameters of theopenings - Through
openings openings FIG. 1 ). The jets streaming outopenings 306 do not have a tangential component in regard to thedome edge 308.
