Description
Technical field
The present invention relates to a kind of for combustion chamber, the burner apparatus of especially gas-turbine combustion chamber, the burner dress
Put and be used for burning fluid fuels.
Background technology
The availability of gas turbine is restricted mainly due to problem present in combustion system.Described problem is particularly
Showed more than emission limit value (NOx and CO) and boom, the boom performance is caused by the thermoacoustic vibration in combustion chamber regions.
In order to which discharge is maintained under limits and showed to suppress the boom of machine, it is necessary to extremely well set
(adjustment) variable combustion parameter.
In the burner with for example main premix burner and igniting premix burner, these parameters are main first
Premix burner and igniting premix burner fuel mass flow.Here, according to setting, about 90%-95%'s
Fuel mass flow passes through main premix burner, and remainder passes through igniting premix burner.It is known that：Igniter gas constitution
The change (being represented with percentage range) of amount stream has shows significant impact for discharge and boom.However, this tune
Save due to unique fuel-grade in igniting premix burner and be restricted.
Therefore, up to now, must be carried out with being expended in the stage of putting into operation before gas turbine is run without friction
Adjustment.Therefore, because few to the setting possibility of main burner and start-up burner, it is necessary to it is empty through narrow passageway to expend ground
Between, the aisle space is limited by discharge and stability.Generally, herein must be between the stable method of operation and small discharge
Make compromise.
In order to realize remedial measure, the fuel-grade of the second premixing can be integrated into start-up burner.The level in
It is that must also be supplied via the fuel conveyor of itself and the fuel channel of itself.
By the embodiment, the two levels can be controlled independently of one another.For example, the two igniter fuel levels can collect
Into into start-up burner blade, to realize the good mixing of fuel and air for the two grades.Therefore, by ingenious
The fuel that ground selection drilling pattern can effectively influence radial direction in operation is distributed and influences discharge and combustion stability.By
This expansible aisle space that must try to pass through in machine starts and stopping, and the row especially in partial load region
Putting performance and stability can be improved.
WO 2014/114533A1 for example disclose a kind of diffusion gas having on the axis of burner apparatus and led to
The burner apparatus on road.The fuel for the second level that the path can be for example used in start-up burner due to tube-in-tube structure is defeated
Send.However, then, due to the expected different heat expansion of component, it is necessary to by consuming and then also relatively expensive balance
Device removes load to tube-in-tube structure.

At least one first gun drilling and at least one second gun drilling of the longitudinal axis extension of burner carrier pipe, for first and the
Two fuel-grades supply fuel.
Thus, the discharge performance and stability of burner apparatus are improved, and can be abandoned with the relative of balancer
Consuming and the tube-in-tube structure of costliness.
Suitably, the first gun drilling and the second gun drilling are set relative to the longitudinal axis of burner carrier pipe on different radii
Put in the pipe wall so that fuel directly can be conveyed to corresponding fuel-grade via the drilling of straight line.The manufacture of this drilling is
Relatively low cost.
In an advantageous embodiment, at least one first gun drilling and at least one second gun drilling are passed through fuel
In each fuel assignment channel of level.Therefore, the quantity of gun drilling can be less than the quantity of the fuel nozzle of each combustion stage.
It is furthermore possible to advantageously：Burner carrier pipe has diffusion gas path, the diffusion gas on its axis
Path is equally passed through in burner head so that can also realize diffusion operation.
In another advantageous embodiment, burner carrier pipe is on fuel flowing direction in burner head upstream with holding
Support plate connects, and wherein loading plate has fuel ring distributor, at least one first gun drilling and at least one second gun drilling
Separated from the fuel ring distributor.
Herein desirably：Loading plate has fuel interface, and the fuel interface is passed through in fuel ring distributor.
On limited spatial relationship advantageously：Fuel interface realizes that the screw-in connects via screw-in connector
Connecing utensil has the opening generally radially in external screw thread and the drilling of insertion, wherein in the state of screw-in, the radial direction
