Definitions
- the invention relates to a steam generator tube with a swirl-generating inner profile. It also relates to a once-through steam generator with such steam generator pipes. The invention further relates to a method for producing a steam generator tube provided with a swirl-generating inner profile.
- a once-through steam generator In the combustion chamber walls of a once-through steam generator are usually employed with one another via webs welded gas-tight steam generator tubes to form a combustion chamber surrounding the gas flue, which are connected in parallel for the flow of a flow ⁇ medium.
- tubes with ⁇ instead of tubes with ⁇ as intermediate, separate flat bar webs may also pipes are used, which are factory equipped with angeform- th fins.
- the steam generator tubes can be arranged vertically or at an angle.
- the steam generator tubes are typically designed so that even at low mass flow density of the steam generator tubes by the flowing medium a sufficient cooling of the steam generator tubes is ensured for a si ⁇ cheres performance of the once-through steam generator.
- the heat transfer ⁇ properties of a steam generator tube An important design criterion, the heat transfer ⁇ properties of a steam generator tube.
- a high heat transfer enables a particularly effective heating of the medium flowing through the steam generator tube with reliable cooling of the steam generator tube itself.
- the heat transfer behavior of a steam generator tube can be impaired in conventional steam generators that are operated at subcritical pressures by the occurrence of so-called boiling crises.
- the pipe wall is no longer wetted by the liquid flow medium - usually water - and is therefore only insufficiently cooled. As a result of Drying out early could then reduce the strength values of the pipe wall.
- steam generator tubes which, as a result of a deformation process (eg cold drawing), have a surface structure on the inside or an inner profile in the manner of helically wound ribs.
- the shape of the ribs which is the steam generator tube Menden throughflow medium is to swirl, so that the pivoting ⁇ eral liquid phase due to the centrifugal forces acting on the tube inner wall collects and forms there a wetting flues ⁇ stechniksfilm. This ensures reliable heat transfer from the inner pipe wall to the flow medium even with comparatively high heat flow densities and low mass flow densities.
- a disadvantage of the known steam generator tubes is that they are comparatively complex to produce due to the limited deformability of the tube material.
- the formability is severely restricted, particularly in the case of high-temperature steels with a high chromium content.
- Such materials play an increasingly important role in steam generator tubes nowadays, since - at least in principle - they allow a steam generator to be designed for particularly high steam parameters, in particular for high fresh steam temperatures, and the associated high efficiency. Due to the material-related restrictions in processing, it is not possible in practice, or only with considerable effort, to produce internally finned tubes with the desired, aerodynamically advantageous finned profiles as part of a deformation process from smooth tubes.
- Steam generator tubes with internals in the manner of twisted tapes are therefore not equally suitable for all the operating conditions that usually occur with steam generators.
- the invention is therefore based on the object of specifying a steam ⁇ generator tube of the type mentioned, which has a particularly favorable heat transfer behavior with simple and inexpensive manufacturing and with a wide range of different operating conditions. Furthermore, a production method suitable for the production of such a steam generator tube and a continuous steam generator are to be specified which have a particularly simple structure with high operational safety and with high efficiency.
- the aforementioned object is achieved according to the invention by an insert disposed in the tube interior to form a drallerzeu ⁇ constricting the inner profile at least, the insert holds a plurality of wires environmentally along writhe in the manner of a multiple thread helically on the tube inner wall .
- the invention proceeds from the consideration that the multiphase flow is to have a swirl within a steam generator tube to improve the heat transfer ⁇ te, so that the liquid phase due to the rotation of the inner pipe wall is guided and wets uniformly as possible. Suitable flow-guiding elements should therefore be arranged in the interior of the tube for the targeted production and maintenance of such a swirl flow.
- the flow guidance is particularly bene- ficial if one hand does not "over-twisting" still too much pressure drops along the flow path occurring defects th ⁇ , on the other hand, the swirl effect is still intense enough to the liquid phase of the flow medium on the ge ⁇ to lead the entire pipe circumference to the inner pipe wall.
- the flow-guiding elements are substantially in the manner of a home should be nenprofils arranged on the inner tube wall and the tube ⁇ cross-section not in the center, or only block slightly.
- the swirl-generating inner profile should be implemented by means of tube internals or inserts which can be produced in the desired shape independently of the steam generator tubes and are subsequently drawn into the tube.
- the new concept presented here provides for wires or strips which, after being introduced into the steam generator pipe, wind helically along the inside wall of the pipe, so that a substantial part of the pipe cross section (more than 50%) remains free and the steam in the thus ak ⁇ accumulate inside pipe and can flow. Furthermore, it was recognized that a simple, ie catchy coil spring generally only generates a weak swirl. The flow can shear over the wire lying against the inner wall of the pipe. Because of the lower rotation the boiling crisis then occurs earlier.
- be ⁇ carries the pitch angle of each wire with respect to a vertically oriented to the tube axis reference plane min ⁇ least 30 ° and preferably at most 70 °.
- a slope angle from the interval 40 ° to is very particularly advantageous
- the respective wire in a round or in sentlichen We ⁇ rectangular cross section.
- the edges may be beitet nachbear- so that comparatively steep Flankenwin ⁇ angle and sharp-edged transitions can be realized.
- the Dräh ⁇ te can depending on the diameter of the steam generator tube and, depending on the intended flow and temperature conditions vary in diameter. In general, a wire diameter or an average cross-sectional dimension of 5% to 15% of the inner diameter of the smooth tube is advantageous.
- the wire material and the internal stress are so matched to the geometric behaves ⁇ nit that a creep or slippage of the individual coils relative to one another prevented.
- ⁇ to additionally or alternatively may be provided by extending in the direction of the tube axis support wires, each of which is fixed to the side facing the pipe interior of the helically wound wires at these a number. In this way, the effect is similar to that of the tion with the radial stiffening struts.
- the support core comprising the stiffening struts and / or the holding wires and / or the center wire can be made of a lower quality material than the twist-producing wires lying against the inner tube wall, since it is only against
- Corrosion or scaling must be protected, but is not directly exposed to the very high temperatures of the inner tube wall.
- the tube insert relatively firmly and securely seated already due to the residual stress of its wires in the steam generator tube is preferably an additional fixing vorgese ⁇ hen, wherein the respective profile forming wire at least at one point, preferably in the vicinity of its two ends fixedly connected to the inner tube wall is.
- the fixed connection is advantageously a high-temperature Schistver ⁇ connection.
- a variant which is somewhat more complex to manufacture, but which ensures particularly secure fixation comprises a plurality of spot welds distributed over the longitudinal extent of the respective wire. The welding fixation can be produced particularly well suited when at least the signals present at the tube inner wall of the insert wires similar Caribbeanset ⁇ Zung are made of a material with a the tube material.
- the Dampferzeu ⁇ gerrohre described herein are used in a fossil-fired-through steam generator.
- By swirl-producing internal profile of the tubes and the associated improvements in the heat transfer behavior also at a boiler constructions with a vertical tube assembly ( "vertical Tubing") ensures a sufficient Wär ⁇ meübertragung to the flow medium or a cooling of the tube walls.
- a Senkrechtberohrung with a higher number of tubes, and with a comparatively short lengths of pipe made possible due to the over obliquely or spirally arranged tubes lower flow rates and lower mass flux operation of the steam generator gers least throughput with reduced pressure loss and reduced min ⁇ .
- In order for the steam generator comprehensive power plant can be designed for a lower minimum load.
- Pipe fittings mentioned may lead ⁇ handy cost savings continue even with convective heating tive as it exists about plants in the heat recovery of gas and steam power, due to the improved heat transfer in a reduction of the heat exchanger surface and to interpret it.
- the above object is solved by a plurality introduced from under tension wires in a plain tube, the wires are arranged in the manner of a multiple thread, and wherein the wires after introducing the extent ent ⁇ be spanned until their turns on the tube inner wall anlie ⁇ gen in other words.
- the more common coil spring formed by the pre-aligned wires is biased by being drills for example, pulled apart or comparable in itself. In this state with a reduced diameter, the insert is drawn into the pipe.
- the wires After his partial relaxation, he presses himself against the inner pipe wall.
- the remaining internal stress of the wires is chosen so that no creep can take place at the intended operating temperature of the evaporator tube.
- the wires are advantageously welded to the inner tube wall at least at one end.
