Abstract

A tower structure of a pre-heating tower of a plant for thermally processing minerals may include a plurality of support beams that extend vertically and parallel to one another and are connected to one another via cross beams. The tower structure may further include a plurality of mounting positions, each mounting position for fitting a platform to the tower structure. A cross-sectional profile of at least two of the support beams changes over a height of the tower structure. Further, at least two adjacent support beams may be configured such that there is a greater amount of space between the beams at a bottom end region of the adjacent support beams than at a region above the bottom end region.

First claim

1 .- 13 . (canceled)

14 . A tower structure of a pre-heating tower of a plant for thermally processing minerals, the tower structure comprising:
support beams that extend vertically and parallel to one another, the support beams being connected to one another via cross beams; and mounting positions, each for fitting a platform to the tower structure, wherein a cross-sectional profile of at least two of the support beams changes over a height of the tower structure, wherein at least two adjacent support beams of the support beams each have a first cross-sectional profile and a second cross-sectional profile, with the first cross-sectional profiles being configured at a bottom end region of the at least two adjacent support beams, wherein the first cross-sectional profiles are configured such that an amount of space between the at least two adjacent support beams is greater below a first or second mounting position of the mounting positions than above the first or second mounting position.

15 . The tower structure of claim 14 wherein the first cross-sectional profiles are disposed below the first mounting position.

16 . The tower structure of claim 14 wherein the first cross-sectional profiles are disposed below the second mounting position.

17 . The tower structure of claim 14 wherein a dismountable cross beam of the cross beams is fitted below the second mounting position between the at least two of the support beams with the cross-sectional profile that changes over the height of the tower structure.

18 . The tower structure of claim 14 wherein none of the cross beams is fitted below the second mounting position between the at least two of the support beams with the cross-sectional profile that changes over the height of the tower structure.

19 . A pre-heating tower of a plant for thermally processing minerals, the pre-heating tower comprising:
a tower structure including:
support beams that extend vertically and parallel to one another, the support beams being connected to one another via cross beams, and
mounting positions, each for fitting a platform to the tower structure,
wherein a cross-sectional profile of at least two of the support beams changes over a height of the tower structure,
wherein at least two adjacent support beams of the support beams each have a first cross-sectional profile and a second cross-sectional profile, with the first cross-sectional profiles being configured at a bottom end region of the at least two adjacent support beams, wherein the first cross-sectional profiles are configured such that an amount of space between the at least two adjacent support beams is greater below a first or second mounting position of the mounting positions than above the first or second mounting position; and
platforms, wherein each platform includes a base plate and a cyclone fitted thereon, wherein in each case one of the platforms is fitted at each of the mounting positions of the tower structure.

20 . The pre-heating tower of claim 19 wherein a height of each of the platforms exceeds a vertical spacing between two adjacent of the mounting positions of the tower structure.

21 . The pre-heating tower of claim 20 wherein at least one of the platforms includes one of the cross beams, which cross beam is fitted between the at least two of the support beams with the cross-sectional profile that changes over the height of the tower structure.

22 . A method for erecting the pre-heating tower of claim 19 of a plant for thermally processing minerals, the method comprising:
erecting or providing the tower structure of claim 19 having the mounting positions for fastening the platforms, with each of the platforms partially or completely configuring a floor of the pre-heating tower;
assembling a first platform of the platforms below a corresponding one of the mounting positions;
raising the first platform that has been assembled up to an upper mounting position;
mounting the first platform at the upper mounting position so that the first platform configures an upper floor of the pre-heating tower;
raising a second platform of the platforms up to a corresponding one of the mounting positions below the first platform; and
mounting the second platform at the corresponding one of the mounting positions for the second platform so that the second platform configures a second floor of the pre-heating tower.

23 . The method of claim 22 wherein the assembly of the first platform occurs at a level below a lowermost mounting position.

24 . The method of claim 22 wherein the assembly of the first platform occurs at a base level within the tower structure.

25 . The method of claim 22 comprising pushing the first platform, once assembled, laterally into the tower structure below the mounting position for the second platform.

26 . The method of claim 22 wherein the raising of the first platform occurs within the tower structure.

27 . The method of claim 22 wherein assembling the first or second platform comprises mounting a cyclone on a base plate.

28 . The method of claim 22 wherein the tower structure is realized by an assembly of profiles composed of steel or concrete so that the tower structure has a wider lateral push-in opening below the mounting position for the second platform than above the mounting position for the second platform.

29 . The method of claim 22 wherein the tower structure is realized by an assembly of profiles composed of steel or concrete so that the tower structure has a wider lateral push-in opening below the mounting position for the first platform than above the mounting position for the first platform.
