Definitions

  • the invention relates to a hot gas cooler according to the preamble of the claim.
  • a hot gas cooler is known from FIG. 1 of the subsequently published EP application 0 024 281.
  • the insert and the shirt are arranged concentrically in this cooler, so that there is an annular space between them.
  • the size of the annulus width results from the thermodynamic conditions to which the cooling surfaces in the hot gas cooler are exposed.
  • the annular space between the insert and the shirt is relatively narrow.
  • the invention has for its object to improve the hot gas cooler of the type mentioned so that it is much easier to drive into the annular space between the insert and the shirt.
  • this object is achieved by the features of the characterizing claim. If one assumes that the insert and the shirt are arranged with parallel n-corner sides for the thermodynamic calculations for the purpose of designing the hot gas cooler, there is a certain constant width for the annular space between the insert and the shirt. In the hot gas cooler according to the invention with the cooling surfaces calculated in this way, the shirt is rotated or displaced relative to the insert, so that one corner of the shirt lies opposite the center of the adjacent side of the insert, so that the distance between the corner and the adjacent side increases than the previously calculated distance for parallel n corner sides.
  • the annular space can be used more easily than for the known hot gas cooler for maintenance and repair purposes, because more space is available in the area of the increased distance, so that the person performing the maintenance and repair work has more freedom of movement.
  • Another advantage can be seen in the fact that the insert and the shirt form a tube sheet on each n corner side, and these tube sheets can easily be produced in the workshop, transported to the assembly site and welded together there.
  • DE-A-1 596 323 discloses a synthesis gas generator with a gas cooler, both of which are arranged in a common pressure vessel.
  • a combustion chamber In the lower part of the pressure vessel there is a combustion chamber, which is followed by an afterburner or reaction chamber, which is surrounded by cooling pipes.
  • an afterburner or reaction chamber At the top of this reaction chamber is a central gas flue with a rectangular cross-section, this gas flue being followed on two sides by two parallel gas flues in which the gas coming from the central gas flue first flows downwards and then upwards.
  • the walls that delimit the throttle cables consist of pipes with webs welded between them. Since the known synthesis gas generator differs from the invention in essential points with regard to the object of the invention and also with regard to the overall construction, it cannot provide a model for the invention.
  • an insert 3 in the form of an elongated prism with a polygonal cross section is suspended on an inner beam ring 2 and a shirt 5 in the form of an elongated prism with a polygonal cross section is suspended on an outer beam ring 4.
  • the tubes 6 of the insert 3 as well as the shirt 5 are bent inwards in an upper region, a part of the tubes 6 of the insert 3, again welded tightly together, one Neck 7 with a hexagonal cross section forms.
  • the remaining tubes of the insert and the shirt, designated 6 ', run in the annular space 11' between the two necks 7 and 9, and finally the ends of all tubes 6 are welded into a hexagonal ring collector 12.
  • the tubes 6 of the insert 3 as well as the shirt 5 are connected at their lower end to a common distributor 14, which also has a hexagonal outline.
  • the tubes of the insert 3 are alternately bent out in the lower end region in such a way that an open tuft of tubes is formed, through which the gas to be cooled can pass from the central drop chamber 10 into the annular space 11.
  • the neck 25 of this funnel penetrates the bottom 26 of the pressure vessel 1.
  • the space between the two Walls of this funnel 23 is filled with water, which is supplied from below (arrow 27) and through holes 28 in the interior of the funnel reaches where it forms a level 24.
  • the neck 7 is connected via a flexible element (not shown) to an inwardly projecting edge 30 of a tube 31 which is lined with insulating stones 32 and which represents the outlet channel of a reaction chamber (not shown) of the coal gasification plant.
  • the tube 31 is surrounded by a connector 34 with a flange 35 attached to the pressure vessel 1. This flange 35 is connected to said reaction chamber in a pressure-tight manner.
  • An opening 40 is provided on the shirt 5, in the area of which part of the tubes is bent out of the plane of the shirt surface and there are no sealing connecting ribs between the tubes.
  • the edge of the opening 40 is connected by a bellows 42 to an outlet line 43, which leaves the pressure vessel 1 through a flexible sleeve 44.
  • distributors 14 and collectors 12 are connected to the other system particles of the steam generator via pipes (not shown) which penetrate the pressure vessel 1.
  • gases from approximately 1,400 ° C. which contain soot and slag particles, flow from the reaction chamber (not shown) of the coal gasification plant through the pipe 31 and the neck 7 into the insert 3, in which - mainly by gas radiation the cooled pipes of the insert - cooling to around 1,000 ° C takes place.
  • the gas flow bends upward into the annular space 11, while the vast majority of the soot and slag particles fall into the funnel 23 and are discharged therefrom with the water flowing continuously through the holes 28.
  • the gases flowing upward in the annular space 11 are further cooled to approximately 400 ° C., whereupon they leave the annular space via the outlet line 43.
  • the further, more problematic cooling takes place in downstream heat exchangers, which preferably also form components of the steam generator system on the secondary side.
  • Insert 3 and shirt 5 are suspended from tie bars 16 and 17 on beam rings 2 and 4, respectively.
  • the drawstrings expediently start from the web plates between the tubes 6.
  • the drawstrings 16 can be connected gas-tight in the region of the upper outer edge of the insert 3 up to the approximately horizontal, tightly interconnected tubes 6 of the shirt 5, so that the fall space 10 and the annular space 11 are completely separated from the space outside the shirt 5 .
  • It can also be expedient, in particular in the upper region of the annular space 11, to have a connection opening. to the room outside the shirt 5 so that there is always a certain pressure equalization over the wall of the shirt and this can not be burdened by greater pressure forces.
  • Similar extensions 53 result between the shirt 5 and the circular cylindrical wall of the pressure vessel 1.
  • the extensions 52 and 53 can be reached via manholes (not shown) in the pressure vessel 1 and in the shirt 5 and / or via the existing pressure vessel openings at 34 and 43.
  • n can be any integer greater than 2.
