Definitions
- the invention relates to a Steam generator combustion chamber, the vertical walls of which are parallel, Pipes that rise flatly to the horizontal have gas-tight over webs or fins are welded, being distributed over the wall width several vertical straps attached to the tubes are provided, which via connecting elements with the Pipe wall are welded. Furthermore, the Invention on a method for producing such Steam generator combustion chamber.
- each carrier tape is enlarged, i.e. in primarily the width of each strap increased will. Problems can then arise by when starting and stopping the steam generator large differences in elongation between the tubes on the one hand and the bandwidth on the other hand occur. This Differences can lead to high voltages at the Lead joints and lead to breakage.
- This Document shows a carrier tape with a U-shaped cross section, which welded to the tubes of the tube wall by connecting elements is.
- the connecting elements with the flanges of the strap welded.
- the disadvantage of this solution is in that if there is a temperature difference between the pipe wall and carrier tape impeded thermal expansion in the direction of the carrier tape width occur which the weld connections between Connection element and flange of the carrier tape on the one hand and web on the other hand strain. To overuse these welds To avoid, the permitted temperature difference must go up be limited, which is tantamount to limiting the Speed when changing loads.
- the invention has for its object a Steam generator combustion chamber of the type mentioned at the beginning to improve that with constructively simple Average permissible temperature gradient greater than can be chosen so far.
- each carrier tape has a U-shaped cross section
- the Web of the U-profile rests on the pipe wall
- the support band in the middle several elongated holes distributed over its length has, in each of which a connecting element in the form of a comb-like cut sheet metal strip is arranged, both with the carrier tape as well as with the neighboring tubes and fins or fins are welded.
- a method according to the invention for producing the combustion chamber is characterized in that on the outside of the from tubes and webs or from fin tubes welded pipe wall with the elongated holes provided straps that are placed in each slot a sheet metal strip provided with comb-like cutouts is inserted by tack welding to the pipe wall is connected that the straps are then removed and the metal strips are welded to the pipe wall, that the carrier tapes are then applied a second time to the Pipe wall are placed, the metal strips the Penetrate elongated holes, and finally under Press the straps against the pipe wall Welded connection between the metal strips and the Carrying tapes is produced.
- the straps in an intermediate step as a template for positioning the metal strips on the pipe wall.
- the combustion chamber 1 shows a not shown Forced-flow steam generator on a combustion chamber 1, the one rectangular or square in plan Surrounds the combustion chamber.
- the combustion chamber 1 has tubes 2 which slightly rising to the horizontal and spiral around the firebox.
- the Pipes 2 form the evaporator surface of the steam generator.
- Fig. 2 and 3 are between the tubes 2 webs 7 arranged and gas-tight with the tubes welded, so that there are tube walls that the Enclose the combustion chamber gas-tight.
- a funnel at the lower end of the combustion chamber 1 according to FIG.
- Support tapes 3 are provided, which have a U-shaped cross section, each of which Web of the U-profile abuts the pipe wall, and the straps 3 extend vertically and even across the width of a combustion chamber wall are distributed.
- the carrying tapes 3 have one Width of at least 200 mm. You are in below described way with the helical extending pipes 2 of the combustion chamber connected and on their upper ends in a known, not shown Way on the vertical pipe sections 2 ' attached so that the load of the combustion chamber 1 including the funnel evenly on the Transfer pipe sections 2 '.
- elongated holes 4 are provided which have been introduced by punching or milling.
- the Elongated holes 4 extend sheet metal strips 5, each comb-like on its edge facing the tubes 2 are cut out, so that the limitation of the Cutouts around the circumference of the neighboring pipe follows and the cutouts lie against the pipes.
- the next to the cutouts remaining sections of the Sheet metal strips 5 lie on the webs 7 of the combustion chamber wall on.
- the straps 3 are also on the Tubes 2 on the entire width of the band, and are on the outside with the metal strips 5 welded (weld seams 9 in Fig. 3 and 4). To do that The straps 3 do not rest against the tubes 2 hinder, the welds 8 along the Cutouts only close to the straps executed.
- the elongated holes 4 are dimensioned somewhat longer than the length of the metal strips 5 to be assembled facilitate.
- the described combustion chamber is manufactured as follows: First, the tubes 2 and intermediate webs 7 on a welding machine Pipe wall sections made from which then pipe walls the desired dimensions can be manufactured. On the The outside of the tube walls created in this way are then the already with the elongated holes 4 carrying straps 3 placed. Then there is a 4 in each slot Sheet metal strips 5 inserted and by means of stitching, which e.g. through the slightly longer elongated holes on the two The ends of the sheet metal strip are made to the pipe wall welded on. The previously used as a template Carrying tapes are then lifted off the pipe wall, whereupon the welding of the metal strips to the Pipe wall by means of the weld seams 8.
- Deviating from the described embodiment can the elongated holes 4 and the metal strips 5 something be dimensioned longer so that the metal strip is three or captured four adjacent tubes.
- the tube walls can also there are gas-tight welded fin tubes.
