Definitions

  • the invention relates to a forced once-through steam generator with a combustion chamber with a surrounding at least partially made of gas-tight welded steam generator tubes Um Publishedswand, wherein within the combustion chamber at least two at least partially formed of further steam generator tubes inner walls are arranged, which are connected in series flow medium side via an intermediate collector.
  • Steam generators with steam generator tubes are for example from the EP 0 320 403 A1 .
  • CN 1 061 653 A US Pat. No. 6,675,747 B1 and EP 0 064 092 A1 known.
  • a steam generator is a closed, heated vessel or piping system designed to produce high pressure, high temperature steam for heating and service purposes (eg, for operation of a steam turbine).
  • water tube boilers are used, in which the flow medium - usually water - is located in steam generator tubes.
  • solid combustion water tube boilers are used, since the combustion chamber, in which the heat is generated by combustion of the respective raw material, can be arbitrarily designed by the arrangement of pipe walls.
  • Such a steam generator in the design of a water tube boiler thus comprises a combustion chamber, the surrounding wall is at least partially formed of tube walls, ie gas-tight welded steam generator tubes.
  • these steam generator tubes initially form an evaporator, into which the unevaporated medium is introduced and evaporated.
  • the evaporator is usually arranged in the hottest region of the combustion chamber. He is downstream of the flow medium, if necessary, a device for separating water and steam and a superheater, in the steam is further heated above its evaporation temperature to be used in a following heat engine such.
  • the evaporator can be preceded by a preheating device (so-called economizer) on the flow medium side, which preheats the feed water by utilizing waste or residual heat and thus likewise increases the efficiency of the overall system.
  • a preheating device so-called economizer
  • steam generator tubes can be arranged within the combustion chamber. These can be summarized or welded to an inner wall, for example. Depending on the desired arrangement of steam generator tubes or inner walls within the combustion chamber, it may be necessary to interconnect interior walls on the flow medium side in succession and to connect their steam generator tubes via an intermediate collector. In the intermediate collector, the medium flow from the upstream inner wall combines and it serves as an inlet header for the downstream inner wall.
  • the object of the invention is therefore to provide a forced flow steam generator, which allow a particularly long service life and a particularly low repair requirements of the steam generator.
  • the invention is based on the consideration that a particularly long service life and a particularly low repair susceptibility of a steam generator could be achieved by avoiding overheating of the steam generator tubes by excessively high vapor contents or enthalpies.
  • these high levels of steam occur in particular by the fact that in intermediate collectors already teilverdampftes flow medium is distributed unevenly to the downstream steam generator tubes.
  • This unequal distribution should therefore be prevented by avoiding a two-phase mixture of water and steam in the intermediate collector.
  • this solution has constructive disadvantages. Therefore, rather, the temperature of the flow medium should be reduced at the entrance to the steam generator.
  • the combustion chamber of the steam generator advantageously has a fluidized-bed firing device.
  • the firing takes place in a fluidized bed of crushed, solid fuel and hot combustion air.
  • the fuel will suspended above the nozzle bed and fluidized.
  • the shredded fuel particles have a large surface area, so that a good burnout can take place.
  • the strong turbulent flow results in a very good momentum and heat exchange, so that a uniform temperature prevails in the fluidized bed. In fluidized bed combustion very low nitrogen oxide emissions can be maintained.
  • the intermediate collector in a further advantageous embodiment, two upstream in the combustion chamber symmetrically arranged, at least partially formed from further steam generator tubes inner walls upstream of the flow medium side.
  • an intermediate collector is required at the transition to the upper combustion zone, so that in particular here the described problems of uneven redistribution occur particularly strongly.
  • Lower temperatures at the entrances of the intermediate collector upstream inner walls are therefore of particular advantage here.
  • fluidized bed boiler with pant leg design have been often performed as a drum boiler, ie the heated medium is separated at the outlet of the evaporator in a water-steam drum in water and vapor content.
  • the problem mentioned at the outset takes a back seat due to the higher medium flow.
  • the embodiment described above also allows a design as a forced flow boiler, which brings several advantages: forced flow steam generators can be used for both subcritical and supercritical pressure without changing the process technology. Only the wall thicknesses The pipes and collectors must be dimensioned according to the intended pressure. Thus, the continuous flow principle meets the globally recognizable trend towards increasing efficiencies by increasing the steam conditions. Furthermore, an operation of the entire system in sliding pressure is possible.
  • the steam generator is therefore designed as a forced flow boiler.
  • the preheating device is designed such that for the entry of the intermediate collector upstream inner wall certain flow medium undergoes a lower heat input than the specific for the entrance of the enclosure wall flow medium.
  • the preheating may comprise a plurality of preheaters, which are connected accordingly.
  • a bypass line branches off before the flow medium-side inlet of a preheater, which leads into the inlet of an intermediate collector upstream inner wall or the intermediate collector upstream inner walls opens.
  • the bypass line comprises a flow control valve.
  • the amount of the branched flow medium is particularly easy to adjust during operation and it is a simple temperature control allows.
  • the inlet of the inner wall or the inner walls flow medium side, a first preheater upstream and upstream of the entrance of Um chargedswand flow medium side, a second preheater, wherein the first preheater has a lower heat input than the second preheater.
  • the inlets of the inner wall or the inner walls and the inlet of Um chargedswand flow medium side, a first preheater upstream and the entrance of Um chargedswand flow medium side is connected in series to the first preheater, a second preheater.
  • the entire flow medium first flows through a first preheater before dividing the flow medium to produce the different temperatures. While a part of the flow medium is supplied to the inlet of the inner walls, is another part fed to another preheater and then the Um intrinsicswand.
  • the advantages achieved by the invention are in particular that the problem of water-steam segregation in the intermediate collector is reliably avoided by the use of two media with different degrees of supercooling for feeding the various evaporator parts (enclosing walls and inner walls).
  • the evaporator does not have to be increased or only slightly enlarged in order to ensure a sufficiently high outlet enthalpy at the evaporator.
  • the special design of the preheater shows structurally particularly simple ways to provide feedwater with different degrees of subcooling available. Overall, a particularly high life of the steam generator is achieved at the same time high efficiency.
  • the steam generator 1 in a schematic representation according to the FIG. 1 is designed according to the invention as forced circulation steam generator. He includes several, formed from steam generator tubes and from bottom to top flowed through tube walls, Namely a perimeter wall 2 and symmetrically arranged, inclined aligned inner walls 4, which is connected via an intermediate collector 6 flow medium side, a further inner wall 8.
  • the continuous steam generator 1 is thus designed in the so-called "pant-leg" design.
  • the flow medium fed to the intermediate collector 6 has a lower temperature than that supplied to the surrounding wall 2.
  • a preheating device 16 is provided, which ensures different heat inputs into the different medium flows.
  • the preheating device 16 after the FIG. 1 includes a preheater 18, the flow medium side, a branch point 20 is connected upstream. A portion of the flow medium is thus passed around the preheater 18 in a bypass line 22.
  • the preheater 18 is initially followed by a further branching point 24, from which a line is led to the inlets 10 of the surrounding wall 2. A part of the preheated flow medium is thus supplied to the enclosure wall 2.
  • One another part of the preheated flow medium is guided in a line which meets in a mixing point 26 with the bypass line 22.
  • a medium slightly lower temperature is achieved by the mixing of the medium streams, which then the inlets 12 of the inner walls 4 is supplied.
  • a flow control valve 28 in the bypass line 22 while the amount of bridged flow medium and thus the temperature of the inner walls 4 supplied flow medium can be easily controlled.
  • FIG. 2 An alternative embodiment of the invention shows FIG. 2 ,
  • the steam generator 1 is here except for the preheater 16 for FIG. 1 identical.
  • the preheating device 16 comprises at its flow-medium-side inlet a branch point 30 from which two lines lead into two preheaters 18, 32.
  • the outlet of the preheater 18 is connected to the inlets 10 of the enclosure wall 2, while the preheater 32 is connected to the inlets 12 of the inner walls 4.
  • the preheater 32 is now configured such that it has a lower heat input into the flow medium than the preheater 18.
  • a lower temperature is achieved at the entrances 12 of the inner walls 4 than at the entrances 10 of the enclosure wall 2.
  • the preheater 18th , 32 the temperature is adaptable to the desired boundary conditions.
  • FIG. 3 A further embodiment of the invention is in FIG. 3 shown.
  • the steam generator 1 is up to the preheater 16 for FIG. 1 identical.
  • the preheating device 16 comprises after its flow-medium-side inlet first a preheater 18, in which the entire flow medium is heated. Then branches off a bridging line 22, which opens into the inlets 12 of the inner walls 4. Another part of the flow medium is fed into a further, downstream preheater 32. Here it is further heated and then the Um chargedswand 4 performed. Due to the additional heating in the preheater 32, this medium has a higher temperature than that guided in the inner walls 4.
