Definitions

  • the invention relates to a steam power plant, consisting essentially of a Steam generator, a turbo group with a condensation steam turbine and generator, a water-cooled condenser and a preheater system heated by tap steam.
  • Such power plants are usually built according to customer specifications and site requirements manufactured and therefore have long times for project development, planning and construction and the associated high costs. Especially the construction period in these power plants, which are oriented towards customer specifications, the fact influences that the most detailed preliminary engineering possible is not possible and essential work, such as the component that processes as early as possible should only be tackled with a delay.
  • the invention seeks to remedy this. Based on the knowledge that the Construction time of a power plant due to the lack of advance planning and adjustment is extremely long in terms of customer specifications today, the invention lies as it is characterized in the claims, the task is a far-reaching Achieve standardization and create a power plant that can be created at a variety of possible locations.
  • the invention is therefore based on a steam power plant, consisting essentially from a steam generator, a turbo group with a condensation steam turbine and generator, a water-cooled condenser and a steam-heated Preheater system and is characterized in that all Components of the steam power plant including the fuel storage area at ground level and are arranged in an open-air installation, the turbo group together the condenser, the preheater with associated pumps and the Transformers are arranged so that they can be painted over by a gantry crane would be.
  • the turbo group is arranged in close proximity and parallel to it aligned.
  • the fuel storage area is a coal dump, it is appropriate to use it - in the Main wind direction seen - downstream of the turbo group and the Arrange steam generator.
  • the advantage of all these measures is that standardization the plant engineering and the components the investment costs reduced to a remarkable extent.
  • the layout of the power plant forms a clearly defined rectangle. This allows the attachment to everyone at any time simply by stringing together such rectangles expand. In doing so, there can be a lot of the usual - in the case of system expansions extensive project engineering can be dispensed with.
  • the to be arranged side by side Power plant blocks are identical; are only the access roads minimally adapt. Another advantage can be seen in the outdoor installation. This can lead to the costly and time-consuming creation of buildings such as e.g. Boiler and machine house can be dispensed with.
  • the measure that the turbo group together with the condenser, the preheater system with associated Pumps and at least the own-use transformers are arranged so that they can be painted over by a gantry crane, also defined for these components a rectangular cross section.
  • This arrangement also enables the shortest possible Connections between the various parts of the system, which in turn is advantageous affects assembly and maintenance.
  • the aimed rectangular Cross-section can also be realized in any case with regard to the local location of the water required for cooling purposes. The respective situation plan is taken into account Of course, this water position, but here also on the shortest connection routes Value is placed.
  • a flat-bed transducer installed at ground level is the task of the unground one Coal provided on the bias belt to the coal crusher. This can help the previously common, large, deep, concreted, underground sensor pit be dispensed with, which considerably reduces civil engineering work.
  • the steam generator is preferably made from coal silos with coarsely ground coal provided. It makes sense if the coal silos assigned to the steam generator with the upstream coal crusher over an at least approximately horizontal running conveyor with connecting transmitter vertical conveyor are connected. Due to the level installation of the horizontal Conveyor equipment can avoid expensive steel structures.
  • the steam turbine has an axial outlet, causing the steam condenser is located in the axial extension of the steam turbine.
  • This Solution due to the quasi-level installation of the turbo group offers, as well as the fact of outdoor installation, allows the unrestricted Access to the condenser. When replacing condenser tubes facade elements are no longer required as before to remove a building. In addition, for such maintenance work gantry crane sweeping the capacitor can be used.
  • a plant module that contains all power plant components contains, designated 200.
  • Such a module could, for example, be a 150th MW plant and is advantageously created in a purely industrial zone, to protect residents from emissions such as dust, noise and truck traffic.
  • the fuel storage location is designated by 6.
  • it is an open coal store with a rectangular plan.
  • the coal is first of all from the stockpile 6 by means of a shovel loader 49 - which during the creation phase can also be used for excavation work poured a flatbed transducer 10 (Fig. 4). From there it gets Conveyed material 41 on the inclined belt 11 leading to the coal crusher 20. As already mentioned at the beginning, the transducer 10 can be used for concreting Pit into which the coal is fed via funnels onto a conveyor belt, to be dispensed with. Since the transducer 10 is at ground level on a foundation plate is reduced compared to the pit solution by the new measure also the length of the bias binding 11, which is usually on the about 15-20 m high inlet of the crusher building 12 must promote.
  • the material to be conveyed first arrives via a horizontal one Conveyor 14 and then via a vertical conveyor 15 to one Horizontal conveyor 43, from which the coal silos 13 are filled.
  • This solution has some of the previously used bias belt conveying to the silos Benefits. Since the loading of conventional boiler silos usually at a height of 50 m, it is necessary for the inclined belt conveyor usual 14 ° - 15 ° inclination of a length of almost 200 m. With the present new measure, this length can be drastically reduced, so that the coal breaker 20 can be arranged in the immediate vicinity of the boiler. Furthermore can the horizontal conveyor 14 at ground level on simple concrete sleepers be erected. On extensive steel structures such as bias belt conveying, which also require a large crane capacity during assembly, can be dispensed with. It goes without saying that access to one in Floor level horizontal conveyor belt due to the elimination of Operating and walkways is facilitated.
  • This type of construction - first horizontal, then vertical - also allows the basic Standardization of the subsequent vertical conveyor 15.
  • This is a jacketed bucket elevator with a simple one Support structure, which is also set up at ground level and to accommodate horizontal loads are preferably connected to the boiler structure. From all of that it follows that only the length of the horizontal conveyor 14 each to different situations, i.e. Distance from the coal pile to the boiler, is to be adjusted.
  • the steam generator 1 works with atmospheric fluidized bed combustion. Here Coarse broken coal with a size of approx. 6 mm can be burned. The advantage can be seen in the fact that apart from the coal crusher 20 no additional Coal mill is needed.
  • the steam generator is in a steel frame held; an outer cladding and a roof can be dispensed with.
  • the steam generator is a tank 24 for liquid Fuel immediately upstream.
  • This liquid fuel is used to start up of the steam generator and for the support fire.
  • the location of this tank is chosen with regard to short funding routes.
  • the tank itself is in a concrete Collection basin housed.
  • the pumps 25 for the starting fuel are located right next to the tank 24 on bases made of a concrete foundation slab stick out. This foundation plate is used as a catch basin for the pump area.
  • the tank can be loaded from road 36 using tank trucks.
  • the pumps 25 for the starting fuel to use both to feed the burners and to charge the tank.
  • Fig. 7 shows how this can be achieved. Sucks to fill the tank the pump 25 via a suitably adjusted three-way member 47 fuel out of the tank truck and conveys it via another appropriately set Three-way organ 46 via filling line 48 into the container. For starting up the steam generator and in case of support fire, the pump 25 conveys this in turn accordingly set three-way organs 47 and 46 the fuel from the tank 24 to boiler 45 of boiler 1.
  • the steam generator 1 works with atmospheric fluidized bed combustion Desulphurization of the flue gases is not necessary. As a result, it closes to the boiler immediately the flue gas cleaning 16, which essentially consists of an electrostatic precipitator or a fabric filter. The cleaned ones Exhaust gases are released into the atmosphere via the chimney 17.
  • Fig. 1 can be seen that the steam generator 1, the flue gas cleaning 16 and Chimney 17 in the longitudinal axis of the boiler in a so-called flue gas axis 18 are arranged.
  • the machine axis 33 now runs parallel to this flue gas axis 18 this axis is the turbo group 2, 3 and the capacitor 4 and the transformers 7 and preferably the outdoor switchgear 34 is arranged.
  • this axis is the turbo group 2, 3 and the capacitor 4 and the transformers 7 and preferably the outdoor switchgear 34 is arranged.
  • Man recognizes the deviation from conventional systems where the turbo group is located is usually located on the front side of the steam generator 1.
  • the road system 36 which is the system, can also be seen in module 200 opens up a workshop 31 and a switchgear building 32, as well as the cooling tower system 35, the leading make-up water 19 and the water treatment 30.
  • the closest possible proximity to the Cooling tower system aimed at condenser 4.
  • the alignment of the cold rooms lined up happens both as a function of the prevailing wind direction and Distance to the turbine and the boiler;
  • the ventilation towers must be ventilated not to interfere.
  • the make-up water withdrawal takes place without the extensive usual so far Infeed drives.
  • the make-up water is in the simplest Funded via a dirty water pump 22.
  • This pump is in the present Example arranged in a concrete tube 21 sunk in the water 20
  • the concrete tube preferably consists of individual ones stacked on top of one another Concrete rings, at least one of which is provided with inlet openings 44.
  • the Tube 21 and pump 22 stand on a thin one embedded in the river bottom Concrete slab.
  • the water is accessible via a catwalk 37 Water pipes 19 run close to the ground and are supported on sleepers 38.
  • Fig. 2 shows one with the same wind direction and the same river course as in Fig. 1 Triple arrangement of modules 200.
  • the only difference to the system according to Fig. 1 can be seen in the continuous streets 36. It can thus be seen that a system can be expanded at any time without impairment the operation of the existing modules. Is already before creation a power plant clearly that it will consist of several modules, so you will of course considerations regarding a common coal dump and make a joint cooling water withdrawal.
  • the crane rails 39 of the gantry crane 8 are supported on both sides on concrete columns 40, whereby the implementation of steam pipes, water pipes and Cable channels are not hindered. In length they are dimensioned so that they the own-use transformer 7 and the feed pump block 26, both in the Machine axis 33 are arranged to include.
  • the crane width is chosen that the crane also the preheater 5 and the container design Switchgear building 32 can also be used. This expresses brought that this crane is also used for the initial construction of the system, which means that there is no need for mobile lifting systems. Is accordingly the lifting capacity of the crane is designed for the heaviest turbine parts, on the occasion assembly must be moved. This does not apply to generator 3, which is preferred is brought into its operating position via slide rails.
  • the term must be relativized at ground level.
  • Tat is a quasi-level lineup, what is meant by it is that it is not a construction where the machine is on a foundation table is parked, which in turn is made of steel or concrete columns will be carried.
  • This creates a quasi-level installation of the machine allows the exhaust steam of the low pressure turbine 2C to be axially aligned and that the condenser neck of the condenser 4 lying on the same level the flue gas is flanged on.
  • This design allows the machine axis 33 is only about 5.5 m above the ground. So there is no need the usual operating platform around the machine and any intermediate floors. Platforms with appropriate stairways are only provided there, where access for operating personnel and for maintenance purposes is absolute is required.
  • the turbo group 2, 3 together with the condenser 4 rests on a simple monolytic one Concrete foundation slab, with protruding from the foundation Pillar plates support the bearings and housings.
  • the necessary ones mentioned above Platforms are approximately 4.5 m above the ground. On them the oil lines are laid.
  • the turbine housings are weatherproof Formwork equipped with appropriately designed ventilation openings. These formworks are also supported on the platforms mentioned.
  • All turbine housings are provided with a horizontal parting line, and at least all steam taps (110 in Fig. 5) are at the bottom Half of the housing arranged. For the maintenance work on the blades or cover of the upper housing halves required on the rotor these lines are therefore not removed. Also has the resulting depth Laying cables above the floor has the advantage that the supports of the pipes can be carried out easily and already on the occasion of the initial assembly undemanding scaffolding can be provided. Access is also at welding, testing and insulation to be carried out.
  • All preheaters 5 have essentially the same dimensions and are designed for the same pressure on the water side. This already indicates that the water-steam cycle is designed so that it does not have a feed water tank / degasser gets along. This large and heavy apparatus, which is usual in itself, is in usually arranged at a height of approx. 15 m and therefore requires more costly Supports. The elimination of this tank and the corresponding piping leads to a significant reduction in investment costs and assembly time.
  • the water-steam cycle is shown in simplified form in the heat diagram of FIG. 5 and briefly explained below.
  • the feed water occurs under normal conditions (170 bar, approx. 250 ° C.) into the economizer 101 of the steam generator 1 and from there it gets into the steam drum 103.
  • the water through the evaporator 102 and fed back into the drum as saturated steam.
  • the multi-part (not shown) superheater 104 it will reach its final temperature heated from 540 ° C and via the live steam line 105 into the high pressure part 2A the steam turbine initiated. Inside the steam relaxes with the release of Performance at a pressure of approx. 40 bar.
  • the steam gets back into the boiler and is there in the reheater heated again to approx. 540 ° and via the hot reheater line 108 introduced into the medium pressure part 2B of the steam turbine. After another partial relaxation The steam passes from the medium pressure part into the low pressure part 2C, in which it is released to condenser pressure. In the water-cooled condenser 4 the steam is deposited, the condensate collects in the not shown Hotwell, from where it goes into the preheater system by means of the condensate pump 111 is promoted. As far as plants are well known.
  • the feed pump 26 is designed in two stages. There is a backing pump on the water side 27 upstream of the preheater 5 and a main pump 28 downstream the preheater arranged.
  • the two-stage feed pump has one common drive 29 provided.
  • the feed water is in the preheaters heated to the boiler inlet temperature by means of tapping steam, which Tapping lines 110 taken from corresponding stages of turbines 2A-2C becomes.
  • the two-stage version of the feed pump has the advantage that all preheaters can be designed for the same low pressure on the water side and are therefore inexpensive to manufacture.
  • the final pressure of the backing pump 27 becomes selected as a function of the pressure loss within the preheater line and the permissible inlet pressure of the main pump 29.
  • a special feature is in the preheater line between condensate pump 111 and Feed pump 27 a compensation tank 23 is provided for cold condensate.
  • This Tank can work with a vapor or inert gas pressure cushion and serves as a template for the feed pump 27. This tank particularly functions in non-stationary operating conditions.
  • the generator 3 is also shown in the thermal circuit diagram in FIG. 5.
  • This generator 3 is air-cooled, with the cooler box 112 flanged directly to the generator is.
  • a special feature is that for recooling those circulating in a closed circuit Cooling air is taken from the main cooling circuit 51, not desalinated cooling water becomes. In contrast to previous air / water coolers, their cooling elements mostly made of copper resp. Stainless steel is used. Nevertheless, the cooling water system becomes cheaper because because of the use of main cooling water for cooling the generator for others Intermediate cooling system required, which with treated water works, can be dimensioned smaller and therefore cheaper.
  • the generator axis is also at a height of approx. 5.5 m Ground is given the possibility of the generator switch, not shown and to place excitation equipment below the generator. You can be placed on a simple concrete slab.
  • the generator leads are therefore arranged on the underside of the generator and run in Row, which leads to the shortest cable lengths. This solution avoids complex Support structures such as those from the lateral outlet of the derivatives above of the generator are known.
  • the own-use transformer and the block transformers are by a Fire protection wall separated.
  • the system is designed so that at least the own-use transformer can be operated from the gantry crane.
  • Switchgear 34 can be designed as a gas-insulated high-voltage module, which significantly reduces land requirements on the one hand and on the other the switchgear can be installed very close to the transformer system.
  • the switchgear and the control room are also designed as containers.
  • the modules are prefabricated using a portal crane on a ground-level foundation plate with all-round base. The space thus created serves as a cable basement.
  • Figures 8 and 9 show the selected principle layout on the one hand in another Wind direction, on the other hand with a different course of the water. Corresponding the default is the coal pile 6 in both arrangements downstream arranged. These figures show the great advantage of the coal mining concept. Only the length and the course of the horizontal conveyor 14 are to adapt to the new conditions. The system in Fig. 9 differs from that in Fig. 8 by the differently running river 20. This leads to the differently designed water withdrawal only to a different Geometry of the module 200.
