Definitions
- the invention relates to a method for operating a stationary gas turbine, which is equipped with a filter for cleaning the intake air. Furthermore, the invention relates to an intake duct for intake air of a stationary gas turbine with at least one filter arranged in the intake duct for cleaning the intake air which can be flowed through the intake duct.
- Stationary gas turbines are usually equipped with filters arranged in the intake duct or in an intake chute in order to clean the ambient air sucked in by the compressor.
- filters are connected in series, which initially removes the sucked in ambient air, also called intake air, from coarser dirt particles and then from smaller dirt particles.
- intake air also called intake air
- the cleaning of the intake air is necessary in order to avoid deposits on the compressor blades and concomitant aging processes of the compressor, which would lead to a reduction of the compressor efficiency and thus to a reduction in the efficiency of the gas turbine.
- it is necessary for the hot gas components used in the turbine that particularly pure cooling air is made available to them, as otherwise there deposits could endanger a reliable cooling of the components.
- the object of the invention is to provide an alternatively ⁇ ven method, an increase in the ist ⁇ added power of the gas turbine, can be done for example for frequency support with the short term.
- Another object of the inven ⁇ tion is to provide an intake duct for a gas ⁇ turbine, with which such a method is feasible.
- the object relating to the method object is achieved with a drive Ver ⁇ solved according to the features of claim 1.
- the object directed to the device is achieved with an intake duct according to the features of claim 3.
- the invention is based on the finding that a pressure loss occurs during operation of the gas turbine due to the air filtering in the intake ⁇ channel. This pressure loss reduces the power provided by the gas turbine and reduces its efficiency. According to the invention, it is now intended to eliminate this pressure loss in the short term and for a short time, and thus an additional power of the gas turbine to the connected Generator can provide.
- a bypass for bypassing the filter or the filter and / or at least one closable opening arranged downstream of the filter or the filter in a wall of the intake duct, preferably in the form of flaps, is provided for the entry of Um ⁇ ambient air.
- This method will preferably be used in the case of frequency support. However, since the particles floating in the ambient air then flow into the gas turbine, it is advantageous to limit this operating phase of the gas turbine in a timely manner. Preferably, it is provided that the operation of the invention a maximum of a predetermined time ⁇ duration, for example, 15 minutes, is performed. Following this phase of operation, ie immediately thereafter or shortly thereafter-within the next hour-a washing of the compressor is preferably carried out. Be ⁇ can purportedly is to introduced upstream of the compressor, a larger amount of a drop-shaped cleaning fluid in the presence suction channel, which then flow into the compressor, where the blading of the compressor kla ⁇ bern can by itself sedimenting while the unfiltered air operation particles. As a result, the short-term aging phenomena in the compressor can be reversed.
- a predetermined time ⁇ duration for example, 15 minutes
- FIG. 1 shows a side view of an intake duct with flaps arranged in the duct wall
- FIG. 3 shows a flowchart of the method according to the invention.
- FIG. 1 schematically shows a stationary gas turbine 10 with its compressor 12, a combustion chamber 14 and a turbine unit 16.
- a rotor 18 of the gas turbine 10 is connected to egg ⁇ nen generator 20, which feeds the electrical energy generated by it into an electrical power distribution network 22.
- an intake passage 30 is provided, which openings 28 of the suction chamber 24 with the input 26 of the compressor 12 connec ⁇ det.
- the filters 32, 34 are used to clean the sucked ambient air A contained therein suspended particles and particles.
- Downstream of the filters 32, 34 are provided in a channel wall of the intake ⁇ channel 30 as closable openings a plurality of large-scale flaps 36 with which the intake port 30 can be connected immediacy bar with the environment and separated from it, see also FIG 2. These are the flaps 36 to one
- the flaps 36 are arranged so that the fürströ ⁇ tion is not disturbed by the still existing filter 32, 34.
- the exemplary embodiments illustrated in FIGS. 1 and 2 differ in that, on the one hand, the arrangement for an alignment (FIG. 1) and a lateral installation (FIG. 2) of the suction chamber 24 on the gas turbine 10 is possible.
- the flaps 36 are closed and the compressor 12 draws in through the openings 28 ambient air A in the intake passage 30 a.
- a request is made to deliver more power than before to the generator 20 to a gas turbine governor. This may be the case, for example, when the mains frequency drops from the power distribution network 22 and thus there is a frequency support event.
- the controller controls the drive unit to open the flaps 36.
- a third method step 44 the flaps 36 are closed again, as a result of which the ambient air A sucked in by the compressor 12 now has to flow through the filters 32, 34.
- the closure of the flaps 36 or the third method step 44 can on the one hand by the termination of the free triggering event or request.
- the flaps 36 can be closed even after a lapse of the maximum operating time of the unfiltered intake of ambient ⁇ air.
- a compressor wash is carried out immediately or shortly after closing the flaps 36.
- the Ver ⁇ dense wash can be performed as online laundry or as offline laundry.
- the invention is operating states for short-term loading such as the grid support mode, the on ⁇ suction losses of a stationary gas turbine 10 through a bypass to minimize and to increase the gas turbine power. Due to the simplicity of the measure according to the invention only small additional costs arise during installation and also in the maintenance of the flaps 36, whereas the economic benefits of the gas turbine 10 equipped with the invention is significantly increased. Of course, other organs such as sliding windows or the like may be provided instead of the flaps 36.
- the invention thus relates to an intake duct 30 for sucked ambient air of a stationary gas turbine 10, with at least one arranged in the intake passage 30 filter 32, 34 for cleaning the air flow through the intake passage 30 intake air A.
- the invention further relates to a method for operating a stationary gas turbine 10th , which is equipped with a filter 32, 34 for purifying the intake air A.
- a stationary gas turbine 10th which is equipped with a filter 32, 34 for purifying the intake air A.
