Definitions
- the invention relates to a premix burner for a combustion chamber of a gas turbine, in particular in a power plant, at least comprising a mixing space limiting housing, an oxidator for feeding a gaseous oxidizer in the mixing chamber, a Gasbrennstoff- supply means for supplying a gaseous fuel into the mixing chamber and a diessigbrennstoffzutax founded for supplying a liquid fuel into the mixing space.
- a premix burner of the aforementioned type is known from EP 0 433 790.
- the generic burner has a housing made up of a plurality of nested trays, which surrounds a mixing chamber.
- the staggered arrangement of the half-shells slots for tangentially supplying an oxidizer, in particular combustion air, formed in the mixing chamber.
- a swirling flow is formed in the mixing space, which becomes unstable at the burner outlet as a result of a jump in the cross section and into an annular swirling flow a backflow in the core passes. This backflow allows the stabilization of a flame front downstream of the burner outlet.
- the burner is equipped with a central lance for supplying a liquid fuel which extends from the burner head into the mixing chamber.
- the lance has at its free-standing, axial end an injection port through which the liquid fuel in the mixing chamber and in the combustion chamber arranged downstream of the combustion chamber of a combustion chamber can be injected. In the generic burner, the injection of liquid takes place
- the characteristic of the injection with respect to penetration depth and mixing of the fuel jets and the fuel distribution along the combustion air inlet slots and the burner axis are given.
- the arrangement of the outlet openings determines the quality of mixing of fuel and combustion air as well as the fuel distribution at the burner outlet. But these variables have a significant influence on the NO ⁇ emissions and extinguishing limit of the burner as well as its stability with regard to combustion pulsations.
- One way to reduce these adverse effects is to deliver all of the required fuel through the central lance.
- the burner is then operated at very high air ratios as a diffusion burner. This results in high flame stability on the one hand, but also very high NO ⁇ emissions on the other.
- This premix burner comprises a housing composed of a plurality of shells, a mixing space into which combustion air introduced via tangentially arranged slots, which passes into a swirling flow in the mixing space, means for introducing fuel into the combustion air flow, these means being a first group substantially Fuel outlet openings aligned parallel to the burner axis for a first fuel and comprising at least a second group substantially parallel to the burner axis aligned fuel outlet openings for a second fuel, wherein the first and the second group are acted upon independently, and these means preferably in the region of the combustion air inlet slots are arranged.
- pilot fuel can also be introduced via a lance.
- the burner can be operated exclusively with liquid fuel, there is the possibility to maintain or repair the gas fuel supply without the operation of the burner or the combustion chamber must be completely interrupted. This is advantageous for the efficiency of the gas turbine equipped therewith.
- the injection of liquid fuel into the mixing chamber of the burner or in the combustion chamber of the combustion chamber usually to significantly increased flame temperatures, which is due for example to insufficient atomization, mixing and evaporation of the liquid fuel before its fertilization. Increased flame temperatures, however, are associated with a disproportionately increased production of NO ⁇ emissions and soot.
- the object of the invention is to provide an improved embodiment for a generic burner, which is in particular comparatively inexpensive to implement and thereby enables a reduction of NO x emissions and soot formation. According to the invention, this object is achieved by the subject matter of the independent claim. Advantageous embodiments are the subject of the dependent claims.

- which has a radial component extending radially to the main outflow direction, wherein the main outflow direction of the burner is to be understood as meaning a direction which comprises the oxidant / fuel mixture flowing out of the mixing chamber at the outlet opening of the mixing chamber.

- several or all fuel injection holes are arranged along the at least one tangential inlet opening for the oxidizer.
- the admixture of the liquid fuel in this embodiment takes place within the tangential inlet opening of the mixing chamber or immediately upstream thereof.
- This injection in conjunction with the turbulent swirl flow within the mixing space, leads to an intensive mixing of fuel and oxidizer. At the same time, this prolongs the residence time of the injected liquid fuel, which likewise improves the mixing and, above all, the evaporation of the liquid fuel.
- the liquid fuel supply device has at least one liquid fuel channel which is connected to the main supply line for liquid fuel which leads to several or all injection holes and which is formed in a tube extending along the at least one tangential inlet opening which is located upstream of the respective inlet opening with respect to the oxidizer flow.

- the said pipe can additionally be used for the operation of the burner with gas fuel the same e- b administrat over the pipe upstream of the respective inlet opening of the Oxida- supply torstrom.
- the tube contains at least one gas fuel channel in addition to the liquid fuel channel.
- the gas fuel imbedded at this point therefore likewise has a particularly long residence time in the burner, which intensifies the mixing with the oxidizer stream.
- the integration of the liquid fuel channel and the at least one gas fuel channel into a common tube thereby reduces the manufacturing cost of the burner.
