Definitions
- the invention relates to a premix burner, in particular for a gas turbine, with a main burner and a den Main burner stabilizing pilot burner. It continues to affect a method of operating a premix burner.
- a burner for a gas turbine is known from US 6202401.
- This burner designed as a hybrid burner, works optionally as a diffusion or premix burner. While at the diffusion combustion fuel and combustion air in the flame is mixed in the premix combustion first the combustion air with the fuel intensive mixed and this mixture then fed to the combustion. This is particularly advantageous in terms of Nitrogen oxide emissions, because in the premix flame due to the homogeneous mixture a uniform flame temperature prevails. The nitrogen oxide formation increases exponentially with the Flame temperature.
- a fuel delivery system a main burner and one pilot burner igniting the main burner.
- the pilot burner flame is monitored by means of a piston in which a Porous material is arranged to absorb a analyzing gas is used.
- EP 1062461 A1 shows a combustion chamber with a lining from heat shield elements.
- a heat shield element is as run a burner heat shield element, the combustion air and fuel is supplied.
- the heat shield element is designed as a pore burner. The combustion reaction takes place here at least partly in a porous material. This will cause the combustion stabilized and the tendency to form combustion vibrations reduced.
- EP 0576697 B1 describes a gas turbine in which in addition to classic burner types, also catalytic ones Burners are used.
- the classic burner types are Premix burners with which the main combustion is carried out becomes.
- catalytic burners a simpler regulation with changing load conditions the gas turbine.
- the invention has for its object a premix burner to be specified in which combustion is particularly low in nitrogen oxides with a low tendency to instability in combustion is possible. Furthermore, a corresponding Method for operating a premix burner and a gas turbine with low nitrogen oxide emissions and low inclination to Burn instabilities can be specified.
- the above-mentioned object is achieved by the features of claim 1. These are for mixing from combustion air with fuel to a fuel gas mixture and for the subsequent combustion of the fuel gas mixture a main burner for most of the combustion air and a pilot burner to stabilize a lean Combustion is provided in the main burner, the pilot burner designed as a pore burner with a burner material which has a fine-pored structure.
- the invention is based on the consideration of the pilot burner a premix burner as a pore burner.
- the pilot burner is the unstable premix combustion of the main burner should be stabilized. Indeed but it could be shown through tests that sufficient by heating the burner material Stabilization through the pilot burner designed as a pore burner is possible.
- the pore burner is then successful can be used if the mass flow rate of the fuel / Air mixture is set correctly.
- the pressure conditions are set so that not by a too high mass flow rate the combustion reaction from the Pore body is expelled.
- the mass throughput but also not be so low that the danger a flashback occurs.
- the nitrogen oxide emissions are caused by a strong heating and thus reduces heat radiation from the burner material, because the flame temperature drops as a result. Furthermore, also the reaction density in the entire burner flame consistent performance is reduced as part of the response in the porous burner material. Furthermore, the combustion due to the particularly low susceptibility of the pore burner stabilized against air or gas fluctuations, whereby especially low susceptibility to Combustion vibrations result.
- the fine-pored structure is expedient by foaming of a basic material. Foaming and subsequent hardening of the base material results in easier Way to a fine-pored structure.
- the burner material is preferably ceramic.
- a ceramic Burner material is particularly characterized by a high Temperature resistance.
- the burner material shows expediently on zirconium oxide or silicon carbide.
- the burner material is a nickel or cobalt based superalloy or a high-temperature steel.
- Even such metallic ones Materials can be used as metal foams, for example Execute fine pores and have a high temperature resistance good processability. Is possible also a metal mesh version.
- the main burner encloses the pilot burner with an annular duct for the combustion air.
- the premix burner is in an appropriate further training in one Gas turbine, in particular a stationary gas turbine, used.
- a stationary gas turbine like this is used to generate electrical energy, there is a reduction in environmental pollution and compliance statutory emissions regulations to a low Nitrogen oxide emission.
- combustion vibrations are in such gas turbines due to high power releases the risk of mechanical damage.
- the gas turbine preferably has an annular combustion chamber.
- an annular combustion chamber it can be done by coupling all Burners for combustion vibrations of particularly high amplitude come. Because of the complex geometry, these are vibrations also practically not to be calculated in advance.
- Figure 1 shows a premix burner 1 with a main burner 3 and with a pilot burner 5.
- the main burner 3 has one Ring channel 7, which surrounds the pilot burner 5 concentrically.
- Swirl blades 9 are arranged in the ring channel 7.
- Combustion air 11 is guided through ring channel 7.
- the combustion air 11 is about not shown hollow Swirl blades mixed with fuel 13 from the swirl blades the fuel 13 is skipped.
- the fuel 13 mixes intensively with the combustion air 11 before it is burned in a main flame 15.
- the main burner is used to reduce nitrogen oxide emissions 3 operated with an excess air of combustion air 11, so that a lean mixture is created.
- the premixing ensures that the mixture is largely homogeneous and thus there is a uniform flame temperature.
- This skinny Premix combustion is difficult to regulate and goes out easily. It is accordingly susceptible to combustion instabilities, through acoustic coupling with the Environment, such as a combustion chamber wall, to create a stable combustion vibration can lead. Such combustion vibrations lead to high noise pollution or even damage to the combustion system.
- the pilot burner is used to stabilize the main flame 15 5. It has a pilot air duct 21 through which combustion air 11 is supplied. Furthermore, the pilot burner points 5 a pilot fuel channel 23 through which the fuel 13 is fed. The combustion air 11 and the fuel 13 are passed through a fine-pored burner material 41.
- the Pilot burner 5 is thereby designed as a pore burner. Before entering the burner material 41, one finds Mixing of the combustion air 11 and the fuel 13 instead of. A combustion reaction is already taking place in the burner material 41. By a pilot flame 25 at the outlet of the Pilot burner 5, the main flame 15 is stabilized.
- the Burner material 41 reduced by equalization and Flame temperature lowering the nitrogen oxide emissions. Farther results in particular from the heating of the burner material 41 a stable, against air or gas fluctuations very insensitive combustion and thus a reduced Tendency to develop combustion vibrations.
- the pilot fuel channel is in the pilot burner 5 shown in FIG 23 from a gas lance 23 and an additional channel 35 composed, which corresponds to the pilot fuel demand more adaptable supply of fuel 13 results.
- the burner material 41 is arranged following an opening 39 of the gas lance 23, one Mouth 39 of the additional duct 37 and the pilot air duct 21 . It is made of a ceramic Foamed material and has a corresponding fine-pored structure. The burner material would also be conceivable 41 to form from a material mixture, one or then removed several components of this mixture that the fine-pored structure of the burner material 41 remains.
- the gas turbine 51 shown in FIG. 3 has one Compressor 53, an annular combustion chamber 55 and a turbine part 57 on.
- the combustion air 11 is in the compressor 53 highly compressed and fed to the ring combustion chamber 55.
- Premix burner 1 of the type described above will be there burned with fuel 13 to a hot gas 59 which is the turbine part 57 drives.
