Definitions
- the invention relates to a fossil-fired once-through steam generator with a throttle cable, the surrounding wall of interconnected gas-tight tubes is formed, which in arranged essentially vertically and parallel on the medium side can flow from bottom to top.
- the surrounding wall is often from heating surface element to heating surface element exposed to different levels of heating. So is usually in the lower part, in which a number of Burners for the fossil fuel are arranged, the heating much stronger than in the upper part. The reason this is also due to the fact that in this upper part often additional heat exchanger surfaces are arranged, which the Surrounding wall against excessive heating, in particular shield by heat radiation.
- the invention is therefore based on the object Steam generator of the type mentioned above to further develop that, on the one hand, adequate cooling the pipes of the surrounding wall are ensured, and that, on the other hand, more individual heating Pipes not too impermissible temperature differences leads between the individual pipes. This is said to be with little Costs can be achieved.
- this object is achieved by that the pipes in a downstairs first Part of the throttle cable has a larger inner diameter have than the pipes in an overlying second part of the throttle cable.
- the first part of the throttle cable below which is in the following as the first section of the perimeter wall is characterized by very high Heat flow densities and good internal heat transfer in the pipes and lies e.g. in the burner area.
- the second part of the throttle cable in the following also as a second section of the surrounding wall is also noted due to high heat flow densities, but a worsened one internal heat transfer in the pipes and lies e.g. in the so-called gas jet room of the steam generator, which is located at the burner area connects.
- the first section of the surrounding wall expediently comprises internally finned, vertically arranged tubes to improve the internal heat transfer. These are preferably dimensioned such that the average mass flow density in the tubes at full load is preferably less than 1000 kg / m 2 s.
- the steam has an average steam content at the outlet of the first section, which is between 0.8 and 0.95 at a partial load of about 40%. Under these conditions, the flow conditions are so favorable that additional heating of individual tubes leads to increased throughput through these tubes, so that only small temperature differences occur at the outlet of the tubes.
- the mass flow density is preferably increased to more than 1000 kg / m 2 s. Therefore, the inside diameter of the pipes at the transition from the first to the second section is reduced while maintaining the same number of parallel pipes or pipe divisions. By reducing the inside diameter, safe pipe cooling is guaranteed even with a high heat flow density in the second section.
- the tubes with the smaller inside diameter of the second section are advantageously directly to the Larger inner diameter tubes of the first section connected so that the pipes of the two Merge sections directly into one another.
- the pipes of the second section can flow at least in the first Part also have internal ribbing.
- a pressure compensation pipe is connected to each pipe.
- the pressure compensation tubes are expedient to one or more outside the vertical Accelerator cable provided pressure compensation tanks guided.
- a steam generator with a high throttle cable e.g. a draw-in type steam generator
- This third part of the throttle cable which is also referred to as the third Section of the surrounding wall is drawn is characterized by a low heat flow density and a moderate internal heat transfer in the pipes and lies in the so-called convection train of the Steam generator.
- the surrounding wall reduces the mass flow density the low heat flux density prevailing there opposite to that in the second section to keep the friction pressure loss in the pipes low.
- the pipes can be made without internal fins be trained.
- the vertical throttle cable of the steam generator 1 according to Figure 1 with a rectangular cross-section is through a Surrounding wall 2 formed at the lower end of the Throttle cable passes into a funnel-shaped base 3.
- the tubes 4 of the surrounding wall 2 are on their Long sides - e.g. over fins 9 ( Figure 2) - gastight interconnected, e.g. welded.
- the floor 3 includes a discharge opening, not shown 3a for ashes.
- a lower or first part 5 of the throttle cable i.e. in a first section of the surrounding wall 2
- tubes 4 the surrounding wall 2 curved; they run on the Outside of the vertical throttle cable. Similar openings can also e.g. for air nozzles or flue gas nozzles be educated.
- a second part 7 of the throttle cable i.e. a second Section of the surrounding wall 2 over which a third or upper part 8 of the throttle cable, i.e. a third section the surrounding wall 2 is provided.
- the first section 5 draws in the burner area is characterized by a very high heat flow density and a good internal heat transfer in the tubes 4.
- the second section 7 is located in the gas jet chamber and is also characterized by a high heat flow density, but also by a smaller, worse one internal heat transfer in the pipes 4 out.
- the third section 8 is located in the convection train and is characterized by a low heat flow density and a moderate internal heat transfer in the tubes 4. This third section 8 is especially with a steam generator in a pull-in construction available.
- the medium side, i.e. of water or one Water-steam mixture, parallel from bottom to top flowed through tubes 4 of the surrounding wall 2 are with their entry ends to an entry collector 11 and with their outlet ends to an outlet collector 12 connected.
- the entry collector 11 and the exit collector 12 are outside the throttle cable and are e.g. each formed by an annular tube.
- the inlet header 11 is via a line 13 and a collector 14 with the output of a high pressure preheater or economizers 15 connected.
- the heating surface the economizer 15 is in the third section 8 of the surrounding wall 2 included space.
- Of the Economizer 15 is during the operation of the steam generator 1 on the input side via a collector 16 connected to the water-steam cycle of a steam turbine.
- the outlet header 12 is via a water-steam separation vessel 17 and a line 18 with a High pressure superheater 19 connected.
- the high pressure superheater 19 is in the area of the second section 7 the surrounding wall 2 arranged. He is during the Operation on the output side via a collector 20 with a High pressure part of the steam turbine connected.
- a collector 20 with a High pressure part of the steam turbine connected.
- the collector 22, 23 between the high pressure part and a medium pressure part of the steam turbine is switched.
- water-steam separation vessel 17 water is discharged via a line 24.
- a pressure compensation vessel outside the throttle cable 26 provided, which is formed by an annular tube is.
- each is in the sections 5 and 7 extending pipe 4 via a pressure compensation pipe 27 with the pressure compensation vessel 26 connected.
- the inside width of the tubes 4 tapers.
- the tubes 4 have a larger inner diameter d 1 in the lower part 5 of the throttle cable the pipes 4 in the overlying second part 7 of the throttle cable, the inside diameter of which is denoted by d 2 .
- the tubes 4 with the smaller inner diameter d 2 are directly connected to the tubes 4 with the larger inner diameter d 1 , ie the tubes 4 merge into one another in the region 25.
- the tubes 4 in section 5 have a thread-like internal ribbing in a manner not shown.
- the tubes 4 are dimensioned in section 5 such that the mean mass flow density there is less than or equal to 1000 kg / m 2 s at full load. The average mass flow density in the tubes 4 is then greater than 1000 kg / m 2 s in the second or middle section 7.
- the tubes 4 again have a larger inner diameter on than in the section below 7. While the tubes 4 also in the second section 7 preferably one over its entire length have thread-shaped inner ribs, are Pipes 4 of the third section 8 only over part of it Provide length with a thread-like internal ribbing. However, it is expedient to use internal ribbing waived.
- the number of tubes 4 in the upper section 8 of the Boundary wall 2 is only half the size of the second Section 7. Therefore, two pipes 4 of the second open Section 7 in an area 30 in a common to them assigned tube 4 of the third section 8 (FIG 1).
- the outer diameter of the tubes 4 in sections 5 and 7 is different and adapted to the respective inner diameter d 1 , d 2 such that the wall thickness of the tubes 4 is approximately the same in all sections 5, 7, 8 is. But it can also be the outer diameter of the tubes 4 in all sections 5, 7, 8 of the same size, so that the wall thickness of the tubes 4 in the middle or second section 7 is greater than in the first section 5 and / or in the third section 8.
- the tubes 4 are provided on their long sides with fins 9 which are used for the gas-tight connection of the tubes 4.
