Definitions

  • the present invention relates to a method for cleaning components of a burner.
  • Gas turbine combustors include a plurality of tubular fuel rail systems configured for different fuels. Each burner has a first end to which fuels can be supplied to the burner via different connections. The first end of the burner opposite the second end of the burner opens in the installed state in the combustion chamber of the gas turbine. The second end is usually provided with a plurality of nozzle systems from which the fuel or a fuel-air mixture can be injected into the combustion chamber. For fastening the burner to a combustion chamber wall, a burner flange encompassing the burner is provided between the first and the second end, which can be screwed to the combustion chamber wall.
  • US 4,995,915 discloses a system for cleaning dirty gas firing nozzles in gas turbines in which a chemical cleaning agent is added to the gas during operation of the gas turbine.
  • the DE 10 2005 009 274 B3 relates to a cleaning method for incinerators having at least one combustion chamber for post combustion of combustion gases, wherein at least one jet of air is injected into the combustion chamber, to improve the afterburning by a turbulence of the combustion gases.
  • the air jet of the DE 10 2005 009 724 If necessary, a twist is occasionally mediated. If the injected air jet already receives a twist for the purpose of better mixing imparted, the spin is thus additionally generated for cleaning purposes.
  • the US 20050000550A1 discloses a mobile cleaning device for cleaning injection needles. This has a housing with a closable lid. Within this Housing the needles are arranged. Also within the housing a tight intermediate plate is arranged; thus a gap is formed. Through this intermediate plate, the individual needles are pushed through. Subsequently, in this intermediate space, a rinsing liquid is introduced which, when the intermediate space is filled, then also penetrates through the needles and thus rinses them.
  • the EP 1 574 675 A2 discloses a mobile cleaning apparatus and method according to the preamble of claim 1.
  • the cleaning apparatus comprises hoses which are attached to the component to be cleaned.
  • the hoses are mounted at the beginning of the component and at the end of the component.
  • liquid is passed through the component with pressure to clean the component.
  • air is pumped through the component to remove the liquid.
  • water is pumped through the component. Then the hoses are removed.
  • the DE 19832767 A1 shows a turbine blade, which is completely immersed in a collecting container with cleaning liquid. This method is therefore particularly well suited for smaller high-temperature components. In one work step, a turbine blade can thus be cleaned. In order to clean all components, they would therefore have to be individually introduced manually in the collecting container, cleaned and then taken out again.
  • the blowing is carried out by means of a rinsing liquid under elevated pressure.
  • the blowing can be carried out by means of compressed air under increased pressure.
  • the pressure vessel may still have a vent and a connection piece for a pump. Other connections, in particular inflows and outflows of the burner are to be closed pressure-tight.
  • the Cleaning of the burner or the components is carried out by means of rinsing with a liquid under elevated pressure.
  • rinsing liquid is pumped from a reservoir for rinsing liquid by means of a pump into the pressure vessel until it is sufficiently filled.
  • the vents is closed.
  • the required rinsing pressure is built up by the pump, which is connected to a rinsing liquid reservoir. By this pressure, the liquid flows through the burner into the sump, thus dissolving deposits, and entrains the dissolved sediment particles.
  • the compressed air When flushing with compressed air, the compressed air is pumped through the inlet openings in the pressure vessel until it is sufficiently filled. If the pressure vessel filled sufficiently enough, the compressed air flows at high pressure through the component to be cleaned and thus dissolves deposits.
  • a particularly efficient cleaning results from the combination of the two possibilities.
  • the cleaning of the burner that is, in particular the individual fuel nozzles and the thus in flow communication inner fuel lines of the burner, by flushing the burner fuel lines with a rinsing liquid under elevated pressure, wherein the flow in the reverse direction - based on the fuel flow direction - he follows.
  • the deposits are dissolved in the interior of the burner and transported away (blow out with rinsing liquid).
  • the rinsing liquid can pulsate, since deposits are removed in the dead spaces of the flow.
  • a further increase in the cleaning effect is achieved by reversing the flow.
  • the air also flows in - in relation to the otherwise flowing fuel -inverted direction, so that the air-blown particles emerge from the burner through the first end. Also, the air flow can pulsate, to prevent the dissolved particles in a line bend deposit (blow out with compressed air).
  • the compressed air and / or the rinsing liquid on particles have a abrasive effect. This also makes it possible to mechanically remove the deposits from the component walls or "knock off" them.
  • the gas turbine 1 has a compressor 2 for combustion air, a combustion chamber 4 and a turbine 6 for driving the compressor 2 and a generator or a work machine, not shown, and an annulus 24 for transferring the hot gas M from the combustion chamber 4 to the turbine 6.

  • the rotor blades 6 serve to drive the turbine shaft 8 by momentum transfer from the hot medium flowing through the turbine 6, the working medium, for example the hot gas M.
  • the guide blades 14 with the end 22 serve to guide the flow of the turbine Working medium, for example, the hot gas M.
  • Each vane 14 has a designated also as a blade root platform 18, which is arranged for fixing the respective vane 14 on the inner casing of the turbine 6 as a wall element.
  • Each blade 12 is attached to the turbine shaft 8 in an analogous manner via a platform, also referred to as a blade root 20.
  • a guide ring 21 is disposed on the inner housing 16 of the turbine 6 respectively.
  • the guide rings 21 arranged between adjacent rows of guide blades serve, in particular, as cover elements which protect the inner wall 16 or other housings against thermal overstress by the hot working medium M flowing through the turbine 6.
  • the combustion chamber 4 is designed as a so-called annular combustion chamber, in which a plurality of burners 10 arranged around the turbine shaft 8 in the circumferential direction open in a common combustion chamber space.
  • the combustion chamber 4 is configured in its entirety as an annular structure which is positioned around the turbine shaft 8 around.

  • the sump 42 may be in fluid communication with the fuel lines stand ( Fig. 3 ).
  • the attachment of the burner 10 via its burner flange 58 ( Fig. 4 ), which can be pressure-tightly connected to the mobile cleaning device by means of a quick-release device.
  • the pressure vessel 32 further comprises a worm gear 36, which has a self-closing closure. This is connected to the movable base 40, which contributes significantly to the mobility of the cleaning device and substantially simplifies positioning of the cleaning device.
  • a mobile device contaminated burner 10 can be achieved directly on the site, on the system or in various cleaning equipment.
  • Fig. 1 further shows the mobile cleaning device with a burner 10 during the blow-out.
  • the mobile cleaning device furthermore has a replaceable cover 34.
  • a replaceable cover 34 About this change cover 34 pilot and diffusion burners can be cleaned with the same mobile cleaning device.

  • the pilot or diffusion burner of a burner 10 is in this case with the aid of the removable cover 34 in the mobile unit. assembled. About the quick-release device of the burner flange 58 is sealed. Thus, burners 10 of different gas turbines can be operated, so that only one cleaning base body is needed.
  • Fig. 3 schematically shows the cleaning of the diagonal grid 52 and the premix 48 by means of the mobile cleaning device.
  • the components of the burner 10 ( Fig. 2 ) are nozzle side into a pressure vessel 32 ( Fig.2 ), wherein the pressure vessel 32 ( Fig.2 ) is closed with a lid 46.

  • the vent opening is opened during filling of the pressure vessel 32 with rinsing liquid and closed during rinsing.
  • the pump By means of the pump, the required pressure is built up in the rinsing liquid, so that the liquid flows against the flow direction of the fuel through the burner 10 and thus entrains deposits with it.

  • Both steps can be carried out in a single cleaning device or in two different cleaning devices.
  • backward blowing with rinsing liquid or compressed air can also be performed separately.
  • the invention provides a highly efficient method for cleaning components of a burner, which can comprise two steps.
  • the first step is mainly for the dissolution of the particles from the base material of the burner and their removal and the second step is mainly used for drying and removal of the remaining particles.
  • the mobility of the cleaning device results in rapid availability of the device at different locations. It can be cleaned by changing the cover with a body different burners of different types of machines. Also, different types of burners such as pilot and diffusion burners can be cleaned. In particular, the cleaning of a pilot burner, in particular a premixed pilot burner, which has even smaller mixing nozzles than the already clogged diffusion burner, can be blown out with the mobile unit. This is particularly advantageous because for pilot burners (diffused and premixed) there is currently no satisfactory solution, deposits efficiently remove from the component.
  • the inventive method can now be dispensed with the disassembly of the burner into individual modules. Furthermore, new component components or manual cleaning are no longer necessary.
