Definitions
- the invention relates to a method for operating an annular combustion chamber as well as an annular combustion chamber with a large number of circularly arranged premix burners, in which a fuel-air mixture is generated before it is used Ignition brought and as a hot gas stream to drive at least one turbine stage a gas turbine plant is used.
- a related ring burner with premix burners for a gas turbine is known for example from EP-B1-597 138.
- the one at the head of the ring combustion chamber Premix burners provided are, for example, from EP-A1-387 532 known.
- Such premix burners are so-called double-cone burners.
- This type of premix burner essentially consists of two hollow, conical partial bodies, which are nested in the direction of flow are. The respective central axes of the two partial bodies are against each other added. The adjacent walls of the two partial bodies form in their longitudinal extent tangential slots for the combustion air, which in this way in the Burner inside.
- a fuel nozzle for liquid fuel is arranged there. The fuel is injected into the hollow cone at an acute angle.
- the emerging conical liquid fuel profile is from the tangentially flowing Combustion air enclosed. In the axial direction, the concentration of the Fuel continuously degraded as a result of mixing with the combustion air.
- the premix burner can also be operated with gaseous fuel.
- gaseous fuel in the area of the tangential slots in the walls of the two partial bodies longitudinally distributed gas inflow openings, the so-called premix holes, intended.
- the premix holes In gas operation, the mixture formation begins with the combustion air thus already in the zone of the entry slots. It is understood that on mixed operation with both types of fuel is possible in this way.
- the fuel concentration is as homogeneous as possible above the applied circular cross-section. It arises at the burner outlet a defined dome-shaped backflow zone, at the top of which the ignition takes place.
- the carbon dioxide emissions as well as the emissions regarding unsaturated hydrocarbons (UHC) and especially the extinguishing limits the respective premix burner is strongly influenced by the size of the backflow zone.
- the individual premix burner also plays the fuel distribution, i.e.
- the mixture profile of the fuel / air mixture in the area of flame stabilization a major role.
- the mixture profile between fuel and air inside the premix burner through the premix perforation pattern determined, i.e. the spatial arrangement of the typically along the air inlet slots distributed openings through which premix fuel, preferably Premix gas is injected into the interior of the premix burner.
- the invention has for its object a method for operating an annular combustion chamber and a related annular combustion chamber with a plurality of circularly arranged premix burners, in each of which a fuel-air mixture is generated before it is ignited and as a hot gas stream for driving at least one turbine stage of a gas turbine system is used to develop in such a way that the disadvantages mentioned above are to be avoided.
- measures are to be taken which decisively counteract the combustion chamber pulsations that occur.
- the burnout should be completed and the CO, UHC, NO X emissions that occur should be reduced.
- the invention is a method for operating a combustion chamber with a plurality circularly arranged premix burner according to the preamble of the claim 1 designed such that at least one premix burner is operated in such a way that the at least one premix burner is one of all other premix burners deviating spatial mixture profile within the fuel-air mixture having.
- the object is also achieved by an annular combustion chamber the preamble of claim 5, solved in that at least one premix burner one of all other premix burners at least one area in the Has premix gas perforation in which neighboring premix gas holes have a different one Have a distance from each other than in the rest of the premix gas perforation.
- the idea on which the invention is based is based on the targeted refraction of the symmetry from the circular arrangement of a large number of identically trained Premix burners around the rotating components of a gas turbine system is structurally predetermined. Since the premix burner is usually identical in construction are arranged in a ring around the rotating components of the gas turbine system, which, due to their identical training, each have identical mixing profiles within of the individual fuel-air mixtures - this is the result of identical ones Premix perforation patterns - form in certain load ranges of the Annular combustion chamber circularly circulating, pulsating waves that need to be targeted suppress.
- Fig. 1 is a longitudinal section along the line I-I in Figure 2 through two adjacent Premix burners 1, 2 are shown, which are arranged side by side on an annular circumferential Front plate 3 of an annular combustion chamber 13 are arranged.
- a schematic View according to line II-II in FIG. 1 on the ring combustion chamber 13 is in of Figure 2 visible.
- the conical premix burners 1, 2 have an outlet opening 4, 5, which open downstream into the combustion chamber 6.
- the premix burner 1, 2 have a premix fuel perforation along their air inlet slots 7, 8 9, which consists of individual openings through which preferably gaseous fuel 10 into the interior of the conical premix burner 1, 2 flows.
- the spatial distribution of the premix gas perforation 9 of the premix burner 1 is shown in conventionally distributed homogeneously, i.e. the premix gas holes are equidistant spaced from each other. With such a premix perforation pattern usually becomes a spatially uniformly distributed, homogeneous mixture profile 11 achieved over the entire cross section of the outlet opening 4.
- the premix burner 2 has two areas along the premix perforation pattern in which the individual premix gas holes 9 different distances to each other.
- a mixture profile 12 is obtained which is designed in the manner of a Gaussian distribution is.
- premix perforation pattern to the premix burner 2 invert, i.e. the mutual distances upstream within the premix burner larger than the premix openings downstream of the premix burner 2, whereby a correspondingly inverted mixture profile with respect to that in FIG Reference to the premix burner 2 shown mixing profile can be generated can.
