Definitions

  • the invention relates to a premix burner arrangement with catalytic Combustion for operating a combustion chamber of a gas turbine arrangement and a method aimed at this, with a premix burner, in which at least a fuel addition unit and supply air openings are provided such that gaseous and / or liquid fuel with combustion air within the Premix burner are miscible and form a fuel-air mixture the premix burner downstream towards the combustion chamber, which the Pre-mix burner assembly is downstream, exits and within the Combustion chamber can be brought to ignition.
  • a generic premix burner arrangement is known from EP 0 833 105 A2 remove.
  • the premix burner described in this publication has one central fuel nozzle axially to the swirl generator, on which there is a downstream Mixing section connects within which the atomized fuel is completely with Air mixed into a fuel-air mixture.
  • the combustion chamber is provided, within which during operation of the Premix burner forms a spatially stable flame zone.
  • combustion chamber vibrations also occur during the operation of known premix burner arrangements, as a result of which the flame stability is severely affected.
  • Such combustion chamber vibrations or pulsations have a particularly disadvantageous effect in operating states in which work is carried out with lean fuel-air mixtures. The result is high, lean extinguishing limits, that is to say an extinguishing of the flame despite a relatively high proportion of fuel, as a result of which the operating range of the premix burners is severely limited, particularly with regard to lean operating mode.
  • the invention is based on the object of developing a premix burner arrangement with catalytic combustion for operating a combustion chamber of a gas turbine arrangement in accordance with the preamble of claim 1 in such a way that, on the one hand, measures are taken by which the NO x emission values are to be considerably reduced. Furthermore, the measures are intended to stabilize the flame within the combustion chamber, so that the operating ranges of the premix burner arrangement are to be enlarged, in particular with regard to an improved lean extinguishing limit.
  • the object underlying the invention is achieved in claim 1 specified.
  • the subject of claim 9 is a method for operating a Premix burner assembly with catalytic combustion.
  • the idea of the invention Advantageously further developing features are the subject of the subclaims as well the description with reference to the embodiments.
  • a premix burner arrangement according to the preamble of Claim 1 further developed such that before the fuel-air mixture enters the combustion chamber a catalyst unit is provided, through which a part of the Fuel-air mixture can be introduced and passes before this part together with the rest of the fuel-air mixture in the Combustion chamber flows in.
  • the premix burner moves in the direction Combustion chamber spreading fuel-air mixture through the catalyst unit through, especially since the catalyst unit is preferably concentric at the outlet of the Premix burner or the mixing section shortly before entering the combustion chamber is arranged so that only peripheral partial flows of the in the direction of Combustion chamber spreading fuel-air mixture through the catalyst unit flow through.
  • Fuel-air mixture from the catalyst unit at least partially catalytically implemented material flow in marginal areas, which is within the Combustion chamber forming flame front, which makes the flame itself clear can be stabilized.
  • the effects of through the peripheral material flows Conditional flame stabilization is particularly evident in operating conditions who work with lean mixtures. A particularly important indicator of positive effect of the peripheral flows entering the combustion chamber is noticeable in the lowering of the lean extinguishing limit, whereby the Operating ranges of the premix burner can be increased significantly. Also combustion chamber pulsations form to a much lesser extent.
  • Fig. 1 is a longitudinal section through a premix burner arrangement with a mixing section shown, which in a conventional manner from the following components is composed.
  • an injection nozzle 2 is provided axially preferably atomized liquid fuel to the premix burner arrangement.
  • air inlet slots 3 is inside the premix burner assembly generates a fuel-air mixture that is downstream, i.e. in the drawing plane 1 from left to right.
  • One of the conical Swirl generator 4 connected downstream of the premix burner shapes the fuel-air mixture a critical number of swirls by which within the combustion chamber 6 can form a stable flame front 7.
  • Subordinate to the swirl generator is a Mixing tube 5, within which the fuel-air mixture completely can mix well before it enters the combustion chamber 6.
  • the catalytic converter unit 8 is arranged upstream in the flow direction Mixing tube 5 completely circular branch duct 9 is provided, through which the peripheral portion of the fuel-air mixture within the Mixing tube 5 is derived in the direction of the catalyst unit 8.
  • the main part of the fuel-air mixture passes axially freely through the mixing tube 5 and arrives within the combustion chamber 6 for ignition.
  • the forcibly removed peripheral fuel-air mixture flows which pass through the catalyst unit 8, are at least partially thermally and / or chemically catalytic implemented and get out of the catalyst unit 8 immediately in the Combustion chamber 6, in which it faces the peripheral areas of the flame front 7 hit and are able to stabilize them.
  • the inner contour of the mixing tube 5 is preferably at the inlet areas of the Discharge channels 9 tapered so that the branch of the peripheral Fuel-air mixture proportions are forced.
  • FIG. 2 Another alternative embodiment is shown in FIG. 2. Also in this Case shows the embodiment of the basic arrangement of a known Premix burner arrangement with central fuel injection 2, one conical trained premix burner, this one in the flow direction downstream swirl generator 4 and one to complete the Mixing of the fuel-air mixture downstream of the mixing tube 5.
  • the combustion chamber 6, which is the mixing tube 5, is not shown in detail is connected downstream.
  • a catalyst unit 8 is provided at the downstream end of the mixing tube 5 such that catalyst material projects into the peripheral edge regions into the interior of the mixing tube 5 and reduces the flow cross section through the mixing tube 5.
  • the catalyst unit 8 is formed from a porous material coated with catalyst material, so that peripheral flow components of the fuel-air mixture which is spreading inside the premix burner unit are forced to flow through the catalyst unit 8, in which they are at least partially converted catalytically.
  • the catalytic conversion takes place either thermally and / or chemically and, in addition to a decisive reduction in the NO x emission values, contributes to the stabilization of the flame front which forms within the combustion chamber.
