Definitions
- the present invention relates to the field of burner technology as it is is used in particular in gas turbines. It affects a fuel lance for injecting liquid and / or gaseous fuels into a combustion chamber, which fuel lance is part of a combustion air jet in a secondary or tertiary burner with a flow around it, and a liquid fuel channel within an outer lance jacket Supply of liquid fuel, a surrounding the liquid fuel channel Gas channel for the supply of gaseous fuel and one the gas channel surrounding air duct for supplying cooling or atomizing air, and first means for radially injecting the liquid fuel from the liquid fuel channel into the combustion chamber and second means for radial injection of the gaseous fuel from the gas channel into the combustion chamber.
- Such a fuel lance is e.g. from an earlier patent application DE-A1-43 26 802 known to the applicant.
- a fuel lance is known from the document DE-A1-43 26 802 mentioned at the beginning known by the applicant currently in their gas turbines (see also the publications US-A-5,341,018, US-A-5,626,017 and EP-A1-0 620 362) is used.
- the nozzles for gaseous fuel and liquid fuel (Oil etc.) are combined.
- the liquid fuel is injected according to the so-called air blast principle, i.e. that as a film on an atomizer lip Applied fuel is in the shear field of the surrounding air flow atomized and mixed with the combustion air as a fuel mist. Does that happen Injection transverse to the direction of flow of the combustion air, so is the depth of penetration determined exclusively by the air pulse.
- the momentum of the liquid Fuel is used only for film production, but not to support the Fuel jet used.
- the object is achieved by the entirety of the features of claim 1.
- the essence of the invention is the liquid fuel by means of a suitable Guide tube arrangement as a plain jet radially to the main flow direction.
- This type of injection means that the liquid fuel stays in the vehicle for a while is reduced in the premixing section and thus less water must be added to prevent a flashback.
- Another advantage is the improved fuel-air mixture due to this arrangement.
- the existing one that has already been optimized for gas injection can be used Air flow field of the main flow also for atomization and mixing of the liquid fuel can be used.
- the injection of the gaseous fuel and the surrounding air jacket turns out to be particularly favorable if according to a second preferred Embodiment the second guide tube in the region of the air duct in the outer diameter tapered towards the mouth, and the first guide tube in the area of the gas channel tapers conically in the outside diameter towards the mouth.
- a preferred embodiment is one in longitudinal section Fuel lance reproduced according to the invention.
- the fuel lance 10 which extends along a lance axis 24, which in turn essentially parallel to the main flow direction 25 of a combustion air flow flowing around the lance is shown in the figure only with its head area.
- a liquid fuel tube 16 In of the fuel lance 10 are located one inside the other concentrically to the lance axis 24 a liquid fuel tube 16, a gas tube 14 and a lance jacket 12 are arranged.
- the interior of the liquid fuel tube 16 forms a liquid fuel channel 17, through which liquid fuel, in particular oil or the like, for injection into Direction of the arrow shown is guided into the lance head 11.
- a gas duct 15 formed by which gaseous fuel in the direction of the drawn Arrow is injected into the lance head 11.
- an air duct 13 is formed through which Air is guided into the lance head 11 in the direction of the arrow shown becomes.
- the liquid fuel from the liquid fuel channel 17 radially injected into the combustion chamber in the form of a plain jet into which the Fuel lance 10 protrudes.
- a first guide tube 23 is provided for injection. which goes in the radial direction from the liquid fuel channel 17 and in Area of a (circular) jacket opening 22 in the lance jacket 12 ends.
- the gaseous fuel is also radially from the gas channel 15 to the lance axis 24 and thus injected into the main flow direction 25 into the combustion chamber.
- a second guide tube 21 is provided, which is in the radial direction starts from the gas channel 15 and also ends in the region of the jacket opening 22.
- Both guide tubes 21, 23 are arranged concentrically one inside the other at a distance, so that the gaseous fuel in the thus formed annular gap between the two Guide tubes 21, 23 is guided.
- the diameter of the jacket opening 22 is relative chosen for the outer diameter of the second guide tube 21 so that a annular gap for generating a protective surrounding the gas jet Air jacket remains free.
- the flow conditions are particularly favorable for the Air jacket flow when the two guide tubes 21, 23 - as shown in the figure - end flush with the inner contour of the lance jacket 12.
- the deflection of the flows out of the gas duct 15 and the air duct 13 the axial direction in the radial direction and the formation of the desired Sheath flows can be further facilitated if the second guide tube 21 in the area of the air duct 14 in the outer diameter towards the mouth tapers, and the first guide tube 23 in the area of the gas duct 15 in the outer diameter tapered towards the mouth.
- air from the air duct can be made in a manner known per se 13 for cooling the head part 18 and for generating an axial air curtain be led into the lance head. Do this on a concentric ring arranged around the lance axis 24 around axial bores 20, through the air in can emerge in the axial direction. The air required for this comes from the air duct 13 brought up via a head channel 19 which in the edge region through the lance head 11 runs. This ensures that the lance head 11 through the air flowing through it is cooled.
