Definitions
- the present invention relates to a refractory pipe wall cladding with a plurality of refractory plates arranged side by side and one above the other, as defined in the preamble of independent claim 1.
- Refractory pipe wall cladding is used, for example, to protect pipe walls in the fire rooms of Kehrncht incineration plants from corrosion by flue gases.
- the pipe walls and pipe wall cladding are often exposed to temperatures of over 1000 ° C in today's waste incineration plants and experience expansions and contractions due to the large temperature differences of the individual operating conditions even when the material is selected appropriately.
- the temperature differences are generally greater for the pipe wall claddings than for the pipe walls, which must be taken into account when choosing the material and / or the design of the pipe wall claddings, so that the pipe wall claddings are not destroyed by greater expansions and contractions than the pipe walls.
- the selection of a suitable material for the pipe wall cladding enables the pipe wall cladding to be matched to the pipe wall for every operating state.
- SiC pipe wall claddings have been preserved, although the SiC content can be very different.
- SiC materials or SiC plates with an SiC content of 30% - 90% are used.
- each plate is held on the one hand by a pin welded to the pipe wall and retained in the direction of the wall, and is also glued to the pipe wall using SiC mortar.
- each plate is hung on a pin-like plate holder that runs diagonally upwards from the tube wall.
- a problem that occurs with both plate systems is the susceptibility to damage of the pipe wall cladding when the waste incineration plant starts up too quickly, since the pipe wall cladding and the pipe wall are heated at different speeds. Because the freedom of movement of an individual plate is restricted by the plate holder and the neighboring plates, the faster expansion of the plate compared to the pipe wall cannot be compensated for if the plate is started too quickly, and the plate and / or neighboring plates are or are broken out or hung out.
- a refractory pipe wall cladding in which a multiplicity of refractory plates arranged next to and above one another with plate holders are held on a pipe wall with pipes connected by webs, whereby the plate holders have no supporting function.
- Several plates arranged one above the other are supported by brackets that are welded to the pipes. The plate brackets are attached to the pipe wall using the brackets.
- the plate brackets have no supporting function, they can be moved vertically on the pipe wall hold.
- welds on the pressure body must be checked by a recognized specialist or an authority. Subsequent changes are therefore relatively complex.
- the invention has for its object to provide a refractory pipe wall cladding of the type mentioned, in which different expansions and contractions of the refractory plates and the clad pipe wall in both the vertical and horizontal directions without damaging the Pipe wall cladding can be caught and can be installed without welding on the pipes.
- Claim 9 relates to a fire-resistant clad wall and claim 11 to a method according to the invention for fireproof cladding a pipe wall.
- Preferred embodiment variants result from the dependent patent claims.
- the essence of the invention is that in the case of a refractory pipe wall cladding with a multiplicity of refractory plates arranged next to and above one another, each with at least one plate holder, which is or are intended to hold the plate on a pipe wall with pipes connected by webs, the plate brackets none
- the plates are carried by at least one bracket independent of the plate holders, the plate holders and the bracket or brackets are designed to be attached to the webs of the tube wall.
- Another advantage is that the plate brackets and the brackets are cooled by their connection to the webs. Since the plates are not rigidly attached to the tube wall, expansion and contraction of the plates can also be absorbed by moving them in the vertical and horizontal directions if the plates are suitably spaced apart.
- a plurality of plates arranged one above the other are carried directly or via the plate or plates arranged below them by a single bracket which is fastened, in particular welded, to the pipe wall when the pipe wall cladding is mounted on a pipe wall.
- the panels carried by the console can then expand and move upwards.
- the increased plate mobility compared to the prior art in this way enables greater expansion and contraction of the pipe wall cladding to be absorbed without damage than the known pipe wall plate systems.
- FIG. 1 shows schematically a front view of a pipe wall cladding according to the invention with a large number of fire-resistant plates arranged next to and above one another;
- FIG. 2 is a sectional view of a refractory plate attached to a pipe wall by means of two plate holders according to the line AA in Fig. 1;
- Fig. 3 is a sectional view of the refractory plate attached to the pipe wall along the line B-B in Fig. 2;
- Fig. 5 - a side view of the tube wall cladding and tube wall part of Fig. 4 and
- Plate 1 has a uniform distance from the pipe wall over wide areas. The ideal distance is approx. 5 mm. It can be adjusted by adjusting the plate brackets 11 before inserting the plate 1. If necessary, the plate 1 must be removed again and the plate holders 11 readjusted.
- the upper edge 12 and the lower edge 13 can be provided with tongue and groove or the side edges 14 and 15 can be complementarily graded.
- Curved edge shapes are conceivable, provided that they prevent gas flowing straight through between two plates arranged side by side or one above the other for all mutual positions that occur in practice.
- a fire-resistant ceramic fiber strip is arranged, which seals the joints between the plates 1, so that no flue gas can pass through the pipe wall cladding to the pipe wall 2.
- Refractory ceramic fiber strips that are heat resistant up to 1350 ° C are available on the market.
- the space between the tube wall 2 and the plate 1 is filled with SiC flow mortar, not shown here, which additionally glues the plate 1 to the tube wall 2. If the plate 1 is moved, cracks form in the mortar or the mortar detaches from the pipe wall 2 or the plate 1. However, this has no negative effects on the tightness of the pipe wall cladding, since this is ensured by the plates 1 and the ceramic fiber strips.
- SiC mortar is let in from above between the plates 1 and the pipe wall 2 and also flows into the slots 16.
- the plate holders 11 are previously surrounded with a refractory foam that remains elastic.
- the SiC flow mortar preferably has an SiC content between 30% and 90%, in particular between 40% and 60%, and a porosity less than 20%, in particular between 13% and 17%.
- An SiC flow mortar which contains 58% SiC, 13% Si0 2 , 26% A1 2 0 3 , 0.2% Fe 2 0 3 and 1.5% CaO has proven to be particularly suitable.
- the plate holders 11 themselves are made of heat-resistant steel, e.g. Steel no.310 according to the AISI standard or material no.1.4845 according to DIN 17440.
- the pipe wall cladding is attached here to a pipe wall 2 ', in which a web 22' is arranged in each case next to two pipes 21 'and 23' lying against one another.
- the plates 1 advantageously have correspondingly adapted rear sides with partially cylindrical cutouts.
- brackets 3 are welded to the tube wall 2 '.
- the brackets 3 each consist of two vertically arranged support plates 31, which are each welded to a web 22 ', and a horizontally arranged support plate 32, which is welded to the two support plates 31.
- Support plates 31 and support plates 32 are made of heat-resistant steel, for example steel No. 310 according to the AISI standard or material No. 1.4845 according to DIN 17440.
- Each console 3 carries a plate 1 lying directly on the support plate 32 and indirectly the plates 1 arranged between this plate 1 and the next console 3 in the vertical direction, each with its lower edge 13 on the upper edge 12 of the plate 1 below lie on.
- the plate holders 11 are only indicated in FIGS. 4 to 6, but not completely drawn.
- the slots 16 do not necessarily have to be T-shaped. There are other forms, such as part of a cylinder, conceivable. It is only important that there is a narrower area between a wider area in the inside of the plate and the rear edge of the plate, so that the plates 1 can be held on the tube wall 2 by means of the plate holders 11. e
