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 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 prior art mentioned, the invention has for its object to provide a steam power plant, which is characterized by a very high maintenance and repair friendliness. In addition, a steam power plant is to be created that achieves extensive standardization and can be built at a large number of possible locations.
  • the invention is thus based on a free-standing steam power plant, essentially consisting of a steam generator, a turbo group with a condensation steam turbine and generator, a water-cooled condenser, a preheater system heated by tap steam and a gantry crane, and is characterized in that all components of the steam power plant, including the fuel storage area , are arranged close to the ground and at least approximately at the same level and the gantry crane covers an area in which the turbo group together with the condenser, the preheater system with associated pumps and the transformers are arranged.
  • 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.
  • turbo group together with the condenser, the preheater with associated pumps and at least the own-use transformers are arranged so that they can be painted over by a gantry crane also a rectangular cross section for these components.
  • This can the system parts are arranged directly next to each other in a very small space without affecting operation and maintenance. For maintenance and repair work can be used on the crane.
  • This arrangement enables also the shortest possible connections between the various parts of the system, which in turn has an advantageous effect on assembly and maintenance.
  • the sensible measure, the coal dump behind the turbo group and Arranging the steam generator affects the need for one rectangular cross section of the system in no way and is independent of the Wind direction feasible. Coal dust emissions in the area of technical Systems and administrative operations can be avoided in this way.
  • the desired rectangular cross section can also be achieved in any case in relation to the location of the water required for cooling purposes. The The respective situation plan naturally takes this water position into account Here too, the shortest connection paths are important.
  • a flat-bed transducer set up 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-scale, deep, concrete, 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, which causes the steam condenser located in the axial extension of the steam turbine.
  • a plant module which 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. In the present case it is an open coal store with a rectangular plan. In the example shown adjoins the coal dump directly on a river 20, which means that the Coal could be delivered by ship. Of course this can also by rail or by truck via access roads 36. Transport via conveyor belts would also be possible if the system is in located near a coal mine.
  • the coal is first removed from the heap 6 by means of a shovel loader 49 - which during the creation phase can also be used for excavation work - on one Flatbed transducer 10 poured (Fig. 4). From there comes the accumulated Conveyed goods 41 on the bias belt 11 leading to the coal crusher 20 already mentioned at the beginning, can be concreted by the transducer 10 Pit in which the coal is fed via a hopper to a conveyor belt is dispensed with become. 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 tape 11, which on the usually about 15 - 20 m high inlet of the crusher building 12 must promote.
  • the material to be conveyed initially arrives via a horizontal conveyor 14 and then via a vertical conveyor 15 to a 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 is at a height of 50 m, it is necessary for the inclined belt conveyor with usual 14 ° - 15 ° inclination of a length of almost 200 m. With the present new measure, this length can be reduced drastically, 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 in the case of bias belt conveying, which also require a large crane capacity during assembly, can be dispensed with. It goes without saying that access to one is at ground level horizontal conveyor belt due to the elimination of operating and walkways is made easier.
  • 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. there 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 Collecting 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 protrude. This foundation plate is used as a catch basin for the Pump area trained.
  • 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 the Burners 45 of the 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 consists essentially 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 are the turbo group 2, 3 and the capacitor 4 and the Transformers 7 and preferably the outdoor switchgear 34 are arranged. You can see the deviation from conventional systems in which the turbo group is usually located on the front side of the steam generator 1.
  • the road system 36 which opens up the system, can also be seen in module 200, 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 cooling tower system should be as close as possible aimed at capacitor 4.
  • For these pipelines is an unearthly one Arrangement chosen to complete the construction work on the occasion of the plant construction not to interfere.
  • the alignment of the lined-up cold rooms happens both as a function of the prevailing wind direction and the distance to the turbine and the boiler;
  • the cooling towers must be ventilated not to interfere.
  • the make-up water takes place without the usual extensive so far Inlet works.
  • the make-up water is very simple promoted 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 stacked concrete rings, at least one of which is provided with inlet openings 44.
  • the tube 21 and the pump 22 stand on a thin concrete slab embedded in the river bottom.
  • the water is accessible via a catwalk 37.
  • the 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 ducts is not hindered. In length they are dimensioned so that they the In-house transformer 7 and the feed pump block 26, both in the machine axis 33 are arranged, include.
  • the crane width is chosen that the crane (8) also the preheater 5 and the container design executed switchgear building 32 can operate with. This expresses brought that this crane (8) also used for the initial creation of the system , which means that mobile lifting systems can be dispensed with. Accordingly the load capacity of the crane is designed for the heaviest turbine parts, which are to be moved on the occasion of assembly. This does not apply to the generator 3, which is preferably brought into its operating position via slide rails.
  • the actual machine here consisting of a steam turbine with a high pressure part 2A, a medium pressure part 2B and a low pressure part 2C and the generator 3 preferably arranged so that the steam the low pressure turbine 2C is axially aligned and that the condenser neck of the condenser 4 lying on the same level is flanged to the exhaust steam.
  • This design allows the machine axis 33 to be only about 5.5 m comes to lie on the floor. This makes the usual operating platform superfluous around the machine and any intermediate floors. Platforms with corresponding Stairways are only provided where there is access for operating personnel and is absolutely necessary for maintenance purposes.
  • the generator switch not shown and to place effector 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 series, which leads to the shortest cable lengths. This solution avoids complex Supporting structures, such as those from the lateral outlet of the derivatives above of the generator are known.
  • 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 above-mentioned required Platforms are approximately 4.5 m above the ground. On them the oil lines are laid.
  • the turbine housings have weatherproof casing equipped with appropriate designed ventilation openings. These formworks are also supported on the platforms mentioned.
  • All turbine housings are provided with a horizontal parting plane, and at least all steam taps (110 in Fig. 5) are on the lower housing half arranged.
  • All turbine housings are provided with a horizontal parting plane, and at least all steam taps (110 in Fig. 5) are on the lower housing half arranged.
  • the resulting deep line routing also has above the floor 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.
  • the chosen arrangement next to the turbine 2 causes short bleed steam lines.
  • the fact that they're not on the boiler side, but lying on the opposite side has the advantage of unbundling the tap steam lines and the one leading to the steam generator Steam lines.
  • the preheater can also be installed close to the floor simple supports in the form of concrete bases, which also serve the feed water pipes and carry the bleed steam lines.
  • All preheaters 5 have and are essentially the same dimensions 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 per se, is usually Arranged at a height of approx. 15 m and therefore requires expensive 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 circuit 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 becomes 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. In it, the steam relaxes while releasing power to a pressure of approx. 40 bar.
  • 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 a common one Provide drive 29.
  • the feed water is heated up in the preheaters the boiler inlet temperature is heated by means of bleed 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 water side can be designed for the same low pressure 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 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.

  • their cooling elements mostly made of copper Stainless steel is used. Nevertheless, the cooling water system becomes cheaper because of the use of main cooling water for cooling the generator for others Intermediate cooling system required for the purpose, which works with treated water, can be made smaller and therefore cheaper.
  • 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 with 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.
