Definitions
- the present invention relates to a burner for operation in a combustion chamber, preferably in combustion chambers of gas turbines / which essentially consists of a swirl generator for a combustion air flow and means for introducing fuel into the combustion air flow, the swirl generator having combustion air inlet openings for the combustion air flow entering the burner and the means for introducing fuel into the combustion air flow comprise one or more fuel feeds with a group of first fuel outlet openings, which is arranged distributed around the burner axis at an end of the burner on the combustion chamber side.
- a preferred area of use for such a burner is in gas and steam turbine technology.
- EP 0 321 809 B1 discloses a conical burner consisting of several shells, a so-called double-cone burner, according to the preamble of claim 1.
- the conical swirl generator which is composed of several shells, creates a closed swirl flow in a swirl chamber which • becomes unstable due to the swirl increasing in the direction of the combustion chamber • and changes into an annular swirl flow with backflow in the core.
- the shells of the swirl generator are of this type composed that tangential air inlet slots for combustion air are formed along the burner axis. At the leading edge of the conical shells at these air inlet slots, feeds for the premix gas, ie the gaseous fuel, are provided, which have outlet openings for the premix gas distributed along the direction of the burner axis.
- the gas is injected through the outlet openings or bores transversely to the air inlet gap.
- This injection in conjunction with the swirl of the combustion air / fuel gas flow generated in the swirl chamber, leads to a good mixing of the combustion or premix gas with the combustion air. With these premix burners, thorough mixing is a prerequisite for low NO x values during the combustion process.
- a burner for a heat generator is known from EP 0 780 629 A2, which has an additional mixing section for further mixing of fuel and combustion air after the swirl generator.
- This mixing section can be designed, for example, as a downstream pipe section into which the flow emerging from the swirl generator is transferred without any appreciable flow losses. The degree of mixing can be further increased by the additional mixing section and thus the pollutant emissions can be reduced.
- WO 93/17279 shows another known premix burner in which a cylindrical swirl generator with a conical inner body is used becomes.
- the premix gas is also injected into the swirl chamber via feeds with corresponding outlet openings, which are arranged along the axially extending air inlet slots.
- the burner also has a central supply for fuel gas in the conical inner body, which can be injected into the swirl chamber for piloting near the burner outlet.
- the additional pilot stage is used to start the burner and to expand the operating range.
- a premix burner is known from EP 1 070 915 A1, in which the fuel gas supply is mechanically decoupled from the swirl generator.
- the swirl generator is here provided with a series of openings through which fuel lines mechanically decoupled from the swirl generator for gas premixing operation protrude into the interior of the swirl generator and feed gaseous fuel to the swirled flow of the combustion air there.
- premix burners of the prior art are so-called spin-stabilized premix burners in which a fuel mass flow is distributed as homogeneously as possible prior to combustion in a combustion air mass flow. With these types of burners, the combustion air flows in through the tangential air inlet slots in the swirl generators.
- Fuel particularly natural gas
- natural gas and liquid fuel mostly diesel oil or Oil # 2
- synthetically produced gases so-called Mbtu and Lbtu gases
- Mbtu and Lbtu gases have recently been used for combustion.
- These synthesis gases are produced by the gasification of coal or oil residues. They are characterized by the fact that they largely consist of H 2 and CO.
- inerts such as N 2 or C0 2 .
- a backup fuel in addition to the synthesis gas from the burner, a so-called backup fuel, can also be burned safely.
- IGCC Integrated Gasification Combined Cycle
- the burner should also function safely and reliably in the mixed operation of synthesis gas and backup fuel, for example diesel oil, the fuel mixture spectrum usable for the burner operation in the mixed operation of a single burner being maximized.
- low emissions NO x ⁇ 25 vppm, CO ⁇ 5 vppm
- a double-cone burner is known from EP 0610 722 A1, in which a group of fuel outlet openings for a synthesis gas are arranged on the swirl generator at an end of the burner on the combustion chamber side around the burner axis. These outlet openings are supplied via a separate fuel line and enable the burner to be operated with undiluted synthesis gas.
- the object of the present invention is to provide a burner which ensures safe and stable combustion both for undiluted and for diluted synthesis gas and has a long service life.
- the burner should in particular meet the requirements mentioned above and, in preferred developments, enable operation with several types of fuel, also in mixed operation.
- the present burner consists of a swirl generator for a combustion air flow and means for introducing fuel into the combustion air flow.
- the swirl generator has combustion air inlet openings for the combustion air flow that preferably enters the burner tangentially.
- the means for introducing fuel into the combustion air flow comprise one or more first fuel supplies with a group of first fuel outlet openings, which is arranged around the burner axis at an end of the burner on the combustion chamber side, ie at the burner outlet.
- the present burner is characterized in that the one or more first fuel feeds with the group of first fuel outlet openings are mechanically decoupled from the swirl generator.
- the geometry of the swirl generator as well as any swirl space that may be present can be selected in various ways in the present burner and in particular have the geometries known from the prior art.
- the distribution of the first fuel outlet openings exclusively at the end of the burner or swirl chamber on the combustion chamber side around the burner axis reliably prevents the synthetic gas from reigniting. Mixing with the combustion air emerging from the burner is nevertheless guaranteed.
- the burner thus enables safe and stable combustion of both undiluted and diluted synthesis gas. This guarantees a high degree of flexibility when using a gas turbine equipped with burners according to the invention in an IGCC process.
- a correspondingly cross-sectional configuration of the first fuel supply means that high volume flows, up to a factor of 7 compared to the supply of natural gas in known burners of the prior art, can be safely conducted to the injection point at the burner outlet.
- the one or more first fuel feeds with the associated first fuel outlet openings are mechanically and thermally decoupled from the swirl generator or the burner shells which form the swirl generator and are significantly warmer during operation.
- the thermal stresses between the comparatively cold first fuel feeds, hereinafter also referred to as gas channels, and the warmer burner shells are avoided or at least significantly reduced.
- the injection region for the synthesis gas in the burner trays is completely cut out.
- the first gas channel is anchored directly in this section of the burner bowls.
- Earlier constructions such as that of EP 0610 722 AI showed problems, for example cracks due to the high stress concentration at these connection points, particularly when connecting a relatively cold gas duct to a hot burner bowl.
- the burner preferably also has one or more second fuel feeds with a group of second fuel outlet openings arranged essentially along the direction of the burner axis on the swirl body.
- a fuel lance can also be provided on the burner axis for the injection of liquid fuel, which projects into the swirl chamber in the axial direction.
- the arrangement and configuration of these additional fuel feeds can be based, for example, on the known premix burner technology according to EP 321 809 or also other types, such as according to EP 780 629 or WO 93/17279.
- Such burner geometries can be designed with the features according to the invention for the combustion of synthesis gases, in particular for the combustion of Mbtu and Lbtu fuels.
- the preferred embodiment of the present burner with one or more further fuel supplies results in a multifunctional burner which is able to store a wide variety of fuels safely and safely - in ⁇
- the burner ensures in particular the stable and safe combustion of Mbtu synthesis gases with heating values (lower heating value Hu or Lower Heating Value LHV) of 3500 - 18000 kJ / kg, in particular 6000 to 15000 kJ / kg, preferably from 6500 to 14500 kJ / kg or from 7000 to 14000 kg / kJ.
- heating values lower heating value Hu or Lower Heating Value LHV
- liquid fuel e.g. diesel oil
- Natural gas can be injected in the burner head either through the burner lance and / or via the second fuel feeds, which are usually formed by the gas channels which are longitudinally attached to the air inlet slots on the swirl generator or swirl body and are known to the person skilled in the art, for example, from EP 321 809 are common. In this way, the burner can be operated with three different fuels.
- the synthesis gas ie the Lbtu / Mbtu fuel
- the synthesis gas is injected radially through the first outlet openings at the burner outlet.
- These outlet openings are small outlet channels, the channel axis of which determines the axial injection angle ⁇ .
- Diameter D and injection angle ⁇ of these outlet openings or channels are special parameters which, depending on the edge Conditions, for example the special gas composition, the emissions, etc., can be appropriately selected by a person skilled in the art.
- the injection angle can be selected so that the channel axes of all outlet openings intersect at a point on the burner axis downstream of the burner or swirl space.
- the injection angle can also be selected so that the channel axes of subgroups of the outlet openings intersect at different points. In this way, any distribution of the injected fuel at the burner outlet can be achieved.
- An injection angle can also be varied in relation to the burner radius.
- the design of the fuel feeds for the combustion of the synthesis gas is adapted to the fuel volume flow, which is up to 7 times greater, and in particular provides the necessary flow cross-sections. They have a multiple cross-section compared to the natural gas feeds.
- Figure 1 in a highly schematic representation of a premix burner, as is known from the prior art.
- FIG. 2 shows a sectional view of the area of a burner on the combustion chamber side according to an exemplary embodiment of the present invention
- FIG. 3 shows a three-dimensional sectional view of a burner which is designed in accordance with the exemplary embodiment in FIG. 2;
- FIGS. 2 and 3 shows an example of the assembly of a burner according to FIGS. 2 and 3;
- FIG. 5 is a highly schematic top view of several different injection nozzles. Geometries for synthesis gas in the burner according to the invention.
- Figure 1 shows a highly schematic of a premix burner, as is known for example from EP 321 809 AI.
- the burner is composed of a burner head 10 and an adjoining swirl generator 1, which forms a swirl chamber 11.
- the conical swirl generator 1 consists of several burner shells, between which tangential inlet slots for combustion air 9 are formed.
- the incoming combustion air 9 is indicated in the figure by the long arrows.
- gas inlets 24 for the supply of a fuel, in particular natural gas 26 can be provided along the tangential inlet slots via the tangential air inlet slots into the swirl chamber 11. This is indicated in the figure with the short arrows.
- a burner lance 14 extends from the burner head 10 into the drain chamber 11, at the end of which a nozzle 16 for injecting liquid fuel 13, e.g. B. oil and / or water 12 is provided.
- the burner is ignited via the burner lance 14.
- the combustion air 9 entering the swirl generator 1 via the tangential air inlet slots mixes with the injected fuel in the swirl chamber 11.
- the resulting closed swirl flow becomes unstable due to the increasing swirl at the end of the swirl chamber 11 due to the sudden cross-sectional widening when transitioning into the combustion chamber and changes into an annular swirl flow with backflow in the core. This area forms the beginning of the reaction zone 17 in the combustion chamber.
- FIG. 2 shows, in a first exemplary embodiment, in a sectional view the region of a burner according to the invention for operation with synthesis gas on the combustion chamber side.
- the Lbtu / Mbtu fuel is injected radially at the burner outlet by means of a gas perforation 18 which is expediently to be selected with regard to diameter D and injection angle, i. H. at the end of the swirl chamber 11.
- This radial injection at the burner outlet enables the hydrogen-rich synthesis gas to be burned undiluted.
- Diameter D and the injection angle of the radial gas injection are special parameters which are appropriately selected by the person skilled in the art depending on the boundary conditions (special gas composition, emissions, ).
- the figure shows the burner shells of the swirl body 1, which enclose the swirl chamber 11. Outside of this swirl body, a gas supply element 2 is arranged, which radially surrounds the swirl body 1 and forms the first fuel supply channel or channels 19 for the supply of the synthesis gas. At the combustion chamber end of this gas supply element 2 are first Outlet openings 18 are formed for the synthesis gas. These outlet openings 18 form outlet channels which specify the injection direction of the synthesis gas. The injection angle ⁇ and the diameter D of these channels or openings 18 are selected appropriately by the person skilled in the art depending on the requirements. In the present example, the outlet openings 18 are arranged in a row around the burner axis 25, so that a homogeneous circumferential injection of the synthesis gas is achieved.
- the comparatively cold fuel supply channels 19 for injection of the synthesis gas and the burner shells of the swirl generator 1, which in principle are significantly warmer, are thermally and mechanically decoupled from one another. This significantly reduces the thermal stresses.
- the connection between the gas supply element 2 and the swirl generator 1 takes place via tabs 3 and 4 provided on both components, which are connected to one another. In this way, minimal thermal stresses are achieved.
- An air flow 8, which is also shown in the figure, tends to stabilize the flames and produces a swirl cooling effect on the burner front before it emerges.
- the opening or the circumferential gap 7 of the swirl generator 1 can also be seen, which is necessary in order to enable a connection between the outlet openings 18 of the gas supply element 2 and the swirl chamber 11.
- Figure 3 shows a trained according to Figure 2
- the swirl generator 1 and also formed from a plurality of burner shells is shown to recognize the gas supply element 2 surrounding it.
- This gas supply element 2 can form an annular supply slot as the fuel supply channel 19 or can also be divided into separate fuel supply channels 19.
- the fuel supply channels 19 for the synthesis gas are adapted for the combustion of the synthesis gas to the up to 7 times larger fuel volume flow in design, and in particular provide the necessary large flow cross sections, as can be seen from FIG. 3.
- the injection area for the fuel i. H. the synthesis gas
- the gas supply element 2 is anchored directly in this section of the burner shells of the swirl generator 1. This solves the voltage problem at the junctures of the cold gas supply element 2 and the warm burner bowl.
- the decoupled solution shown in this example achieves the required burner life.
- the injection of the synthesis gas is indicated in the figure by the reference number 20.
- additional gas injection channels 24 can also be provided along the swirl generator 1, in the same way as can be seen in FIG. 1, for example, with which natural gas 26 can be introduced into the swirl chamber 11 upstream of the injection point of the synthesis gas.
- the injection Oil or an oil-water emulsion is indicated schematically at the end of the swirl chamber 11 on the combustion head side, as is the inflow of combustion air 9 via the tangential inlet slots.
- FIG. 4 shows an example of the assembly of a burner according to FIGS. 2 and 3 from the two subcomponents, the gas supply element 2 and the swirl generator 1.
- the gas supply element 2 with the integrated one or more fuel supply channels 19 for synthesis gas and the combustion chamber side is arranged around the burner axis 25 Outlet openings 18 are preferably produced together with the swirl generator 1 as a cast part and then separated.
- Assembly takes place by the swirl generator 1 being inserted axially into the gas supply element 2, so that the outlet openings 18 of the gas supply element 2 come to lie in corresponding openings 7 of the swirl generator 1.
- an element 6 of the swirl generator 1 is held in the sliding seat in a counterpart 5 of the gas supply element 2, so that thermal expansion differences between swirl generator 1 in the gas supply element 2 in the area of the burner head can be freely compensated.
- the connecting straps 3 of the gas supply element 2 and the connecting straps 4 of the swirl generator 1 are connected to one another in a suitable manner, for example welded, and form the only fixed bearing of the swirl generator 1 in the gas supply element 2.
- the outlet opening area of the gas supply element 2 is free in the Openings 7 of the swirl generator 1 are movable.
- the production of both elements from a single cast enables low manufacturing tolerances, so that a circumferential gap dimension s shown in FIG. 2 between swirl generator 1 and gas supply element 2 can be minimized.
- a correspondingly high accuracy of fit with a small gap dimension s in the area of the gas outlet openings 18 or the openings 7 of the swirl generator 1 minimizes an untwisted combustion air emerging through this gap, which could have potentially negative effects on the combustion stability.
- FIG. 5 shows various examples of differently selected injection directions of the first outlet openings 18 at the end of the swirl chamber 11 for the synthesis gas.
- FIG. 5a shows in a highly simplified representation a top view of the burner outlet and the injection axes of the synthesis gas injection 20 of the individual outlet openings 18, which intersect at an intersection point 21 on the burner axis.
- FIG. 5b shows another embodiment in the same view, in which the outlet axes of the synthesis gas injection 20 of different groups of outlet openings 18 intersect at different intersection points 21, which are distributed over the outlet cross section of the burner.
- the distribution of these intersection points 21 can be chosen arbitrarily in order to adapt the injection to the respective conditions. On the one hand, this affects the position of the intersection points 21 and on the other hand, of course, their number. In the same way, it is possible to select the intersection points 21 at a different distance from the burner exit plane or at the same distance, as is shown schematically in FIGS. 5c and 5d.
- FIG. 6 shows an example of a swirl generator 1 with a purely cylindrical swirl body 23 in which a conical inner body 22 is inserted.
- the pilot fuel can be supplied directly to the tip of the conical inner body 22.
- the outlet openings 18 for the synthesis gas are distributed around the burner axis 25 at the end of the swirl chamber 11 on the combustion chamber side.
- the fuel supply channels 19 are not shown in this illustration.
- additional gas outlet openings for natural gas, including the supply lines 24 required for this, can additionally be provided at the tangential air inlet slots (not shown).
- a mixing tube for generating an additional mixing section can be connected to the swirl generator 1, as is known from the prior art.
- FIG. 7 finally shows an example of a burner in which the swirl generator 1 is designed as a swirl grille, by means of which the combustion air 9 entering is swirled.
- An additional fuel for premix loading can be introduced into the combustion air 9 via the supply lines 24 leading to outlet openings in the area of the swirl generator 1.
- the supply of the pilot fuel 15 is via a central in the Internal volume 11 projecting nozzle 16 realized.
- the outlet openings 18 for the synthesis gas are distributed around the burner axis 25 at the end of the inner volume 11 on the combustion chamber side and are supplied with synthesis gas via the fuel supply channels 19.
